I . INTRODUCTION 

1 .1 Overview 

The field activities of the Physical Oceanographic Field Program Offshore 

North Carolina were initiated in February 1992 and completed in February 

1994 . During this period, twenty-three current meter moorings were 

maintained at fifteen different locations off the coast of North Carolina 

and a total of fifty-one (51) current meter levels were maintained and 

rotated on a quarterly or semi-annual basis . in addition, quarterly 

hydrographic surveys (CTD casts) were made along a standard grid within the 

study area and both drogued and undrogued ARGt)S-tracked drifters were 

deployed at five shelf locations during each survey . Meteorological data, 

water level data and satellite imagery data were also acquired in support 

of this program. Two nearshore studies were completes using Davis-type GPS 

drifters . This document summarizes the location, quality and quantity of 

all of these observations . An earlier annual report in 1993 presented the 

mooring designs, descriptions of the data logging instruments, and data 

processing procedures . These issues are not discussed again in the present 

document . 

1 .2 Operations Sununary 

The M/V SEAWARD EXPLORER was utilized for the initial mooring deployment 

cruise in February 1992, for all four cruises in 1993 and the final cruise 

in February 1994 . In April, August and November 1992 the R/V CAPE HENLOPEN 

served as a platform for field activities_ Special Event Surveys were 

conducted during the August and November 1992 cruises while aboard the R/V 

CAPE HENLOPEN . The M/V SEA DRAGON was used for Nearshore Drifter Studies 

in June and September 1993 . 

The NC State Ports Authority in Morehead City, NC served as a mobilization 

point for all current measurement and offshore hydrographic efforts . Two 

different sites in Rodanthe, NC served as shore support stations for the 

tracking of GPS drifters during the Nearshore Drifter Studies . Access to 

the ocean area off Rodanthe was through Oregon Inlet via Roanoke Sound .

II . LOCATION OF FIELD OBSERVATIONS 

2 .1 Introduction 

The figures and tables presented in this chapter document the locations and 

types of field measurements made or acquired during the program. The 

actual data acquisition associated with each cruise is summarized in Table 

2 .1-1 . Additional data were acquired from government agencies which 

routinely and continuously collect certain parameters as part of their 

public mission. These type data include coastal and offshore meteorological 

data and coastal water level data . 

2 .2 CTD Station Locations 

,~ The CTD stations occupied during the Quarterly Surveys are presented in 

Figures 2 .2-1 through 2 .2-8 . These locations are also presented in tabular 

form in Table 2 .2-1 through 2 .2-8 . The stations occupied during the 

Nearshore Studies are presented in Figures 2 .2-9 and 2 .2-10 and in the 

corresponding tables (Tables 2 .2-9 and 2 .2-10, respectively) . 

2 .3 Drifter Deployment Sites 

Aanderaa (Draper) ARGOS drifters (with holey sock drogues) were deployed 

during Quarterly cruises at five locations on the shelf (see Figure 2 .3-1 

and Table 2 .3-1) . Position 3 was used only once . In addition, a number of 

Aanderaa oil tracking drifters (without drogues) were deployed at these 

same sites . These latter drifters were provided by MMS and were deployed 

' but not tracked as part of this program. 

Brightwater GPS drifters and Technocean ARGOS drifters were deployed during 

the Nearshore Studies at the sites identified in Tables 2 .3-2 and 2 .3-3 . 

These locations are shown in Figures 2 .3-2 and 2 .3-3, respectively . Both 

are Davis-type drifters . 

2 .4 Current Meter Mooring Locations 

``J Figure 2 .4-1 shows the mooring locations and Table 2 .4-1a through 2 .4-1f 

tabularizes them . This table also presents the specific instrument type, 

serial number and measurement level for each quarterly deployment over the 

two year study . 

2 .5 Meteorological and Water Level Stations 

Figure 2 .5-1 shows the locations of the meteorological and water level 

stations utilized in this study. Table 2 .5-1 provides the locations of the 

NWS and NDBC meteorological stations, and Table 2 .5-2 provides locations 

for the National Ocean Survey (NOS) sea-level recording stations .

III . CTD AND CURRENT METER CALIBRATIONS 

3.1 CTD Calibrations 

Three different Neil Brown Mk IIIB CTDs and a SeaBird SBE-19 SeaCat CTD 

were used during the field program. SAIC's Neil Brown Mk IIIB was 

recalibrated at Neil Brown (EGG) prior to the beginning of the field 

program (on January 16, 1992) and a 1600 dbar unit belonging to the 

University of Delaware (used on the R/V CAPE HF-X:,QPEN) was recalibrated 

twice (on January 27, 1992 and again on October 27, 1992 .) Also, a second 

University of Delaware Mk IIIB CTD (a 3200 decibar unit) was recalibrated 

on February 10, 1992 . The SeaBird SeaCat CTD (used during the Nearshore 

Study) was recalibrated on October 28, 1992 . 

J During each quarterly cruise, salinity samples were collected at each 

station. During the Nearshore Studies salinity samples were collected at 

-, two or three stations along each line . After each cruise samples were 

shipped to Texas A&M University where they were run on a Guildline 

conductive salinometer . The raw CTD data were then compared with salinity 

samples collected in mixed layers . The results of these intercomparisons 

for the quarterly cruises are presented in Tables 3 .1-1 through 3 .1-8 and 

are summarized in Table 3.1-9 . Similar tables for the two Nearshore 

Studies were not generated due to the absence of mixed layers in the 

.~ shallow coastal zone . However, it is noted that the observed bottle 

salinity values did occur within gradients of the meter averaged CTD 

profiles within a meter of the depth at which the water samples were taken . 

' A pressure affect on the University of Delaware's shallow (1600 dbar) Neil 

Brown unit's conductivity head was detected in data for Cruise III (19 

August-5 September 1992) aboard the R/V CAPE HENLOPEN . Subsequently, a 

depth dependent equation was fit to the data and corrected CTD salinities 

were determined . The results of this fit are shown in Table 3 .1-2a . The 

standard deviation (0 .029) in the Cruise II (28 April-10 May 1992) salinity 

data is high but is not readily explainable . Otherwise, the CTD salinity 

l data, and by inference the temperature data, are of excellent quality for 

the entire field program. 

3 .2 Current Meter Calibrations 

All current meters used in the program were calibrated at the respective 

manufacturer's facilities prior to the initiation of the field work . In 

addition, a small number of instruments (mostly S9s) were periodically 

recalibrated during the program in conjunction with repairs by the 

manufacturer at the manufacturer's facilities . All instruments on hand at 

the conclusion of the field effort were recalibrated before being returned 

to MINIS or the SAIC Service Center . Tables 3 .2-1 through 3 .2-3 present the 

dates for these calibrations . The Aanderaa RCM-5/8s and RCM-8s were 

recalibrated at the Northwest Regional Calibration Center ; and the General 

-_ Oceanics Mkls and Mk2s, and the InterOcean S4s were recalibrated at their 

respective manufacturer's facilities . 

No calibration problems were detected with any of the Aanderaa current 

meters . One General Oceanics Mk2 current meter (serial number 459) 

produced questionable directional data during the field effort (at the 30m 

level at C2) . However, extensive testing of the instrument at General 

Oceanics following final recovery revealed no detectable problems . 

Instrument 291 had an intermittent problem with its tilt sensor causing it

to stick. The tilt sensor on this unit was replaced and the current data 

were discarded. The pressure sensor on instrument 331 was found to be 

slightly out of calibration but was not replaced and no correction was 

applied to the data . Finally, two of the InterOcean S4s (serial numbers 

08111746 and 08161753) produced large zero current offsets (>2 .00 cm/s) in 

their VN and VE components during near-zero current tub tests (at SAIC) and 

post-deployment calibration checks (at InterOcean) . These results are 

presented in Table 3 .2-4 . Dr . Peter Hamilton reviewed the last field data 

for these two instruments and noted that there appears to be no indication 

that these large offsets affected the data for the last three-month 

deployments at B2(5m) and A3(Sm), respectively . This suggests the 

possibility that the electrode surfaces of these instruments may have been 

damaged during the final instrument recoveries . Two electrodes on serial 

number 08111746 and all four electrodes on serial number 08161753 were 

replaced before final recalibration .

IV . INSTRUMENT PERFORMANCE AND DATA RETURN 

J 

4 .1 Introduction 

Generally, the instrument performances for the data acquisition systems 

used in this program were quite good . The one exception was the early 

performance of the S4 current meters . Here, a surprising number of 

interrelated and unrelated problems were encountered requiring a 

substantial and cooperative effort on the part of the manufacturer in order 

to be resolved . Details are presented in Section 8 .4 .2 . CTD and drifter 

performances are discussed in Sections 4 .2 and 4 .3, respectively . All 

available and useful meteorological and water level data are identified in 

time in Section 4 .5 and the number of available satellite images are 

identified in Section 4 .6 . 

4 .2 CTD Data 

All of the CTD stations occupied have produced useful data though the total 

number of stations varied from cruise to cruise, primarily due to weather 

conditions . No CTD data were collected in February 1992, only 16 stations 

were sampled in February 1993 and only 4 stations were occupied in February 

1994 . This was due primarily to the need to rotate the current meter 

moorings in what good weather was available . Table 4 .2-1 summarizes the 

number of CTD stations sampled during each cruise . 

4 .3 Drifter Data 

4 .3 .1 Aanderaa ARGOS Drifters 

Thirty-six Aanderaa (Draper) ARGOS drifters (LCDs) with 2 .5 m long holey 

sock drogues and one meter tethers were deployed at six locations on the 

shelf. These were considered expendable and no attempt was made to recover 

them, though three units were returned following recovery in England (1), 

and France (2) . A fourth unit was reported recovered in the Canary Islands 

but was never returned . One unit was destroyed in the ship's screw during 

deployment and two others produced no data after deployment . One unit was 

confirmed to have been picked up after about six days and three others 

ceased operation while still in the study area 12 to 20 days into their 50, 

40 or 30 day transmission schedules . It is unknown whether these latter 

three drifters were picked up, were run over by other offshore traffic, or 

simply stopped working . No effort was made to evaluate the drifters' 

performances once they left the study area . The useful data return in days 

is summarized in Table 4 .3-1 . 

As noted above, four drifters were recovered many months after they left 

the study area . The recoveries in England and France were after 14 to 17 

months . The recovery in the Canary Islands was after 23 months . The three 

returned drifters had been recovered without their holey sock drogues 

attached and with most paint worn away (See Figure 4 .3-1) . 

A small number of drifters (<5) turned on again many months after they had 

turned off . This was not supposed to happen and resulted in the receipt 

of some interesting but unnecessary data . The manufacturer interacted with 

ARGOS to pick up some but not all of the additional ARGOS costs . One 

example of this on/off/on phenomena is presented in Figure 4 .3-2 for the 

66 
Table 4 .2-1 CTD data acquisition summary for the NC Field Program .

4 .3 .2 Brightwaters Davis-Type GPS Drifters 

The Brightwaters Davis-type GPS drifters performed well and produced clean 

records . Two units, however, had defective GPS mastheads (serial numbers 

06 and 07) which failed early in the study . A third unit had reduced 

telemetry range due to a damaged VHF antenna (serial number 08) . This VHF 

antenna damage occurred during a beaching in heavy surf . In addition, one 

of the drifter night lights flooded early during the initial Nearshore 

Study and subsequent deployments of all drifters were made without the 

light . No instrument electronics compartments flooded and no drifters were 

lost . Several units took quite a beating, however, coming ashore in heavy 

surf . This resulted in breakage of some of the fiberglass sail support 

rods and tearing of some of the sails . These were replaced and the 

instruments were redeployed . A summary of the data return for these 

deployments is presented in Table 4 .3-2 . Drifter serial number 10 was used 

as a shore station and so is not listed in the table . Drifter serial 

number 12(13) was a composite assembled from two Brightwaters drifters 

belonging to Woods Hole . 

VHF tracking from shore stations with directional antenna heights on the 

order of 40-50 feet provided a maximum tracking range of approximately 10 

nautical miles . Offshore, with a somewhat lower (20-25 feet) omnidirectional antenna, on a 31 foot vessel, a maximum tracking range of three 

to four nautical miles was obtained . VHF contact with the drifters was 

supplemented by loosely attaching an 11" diameter Metocean ARGOS sphere (by 

an eighteen inch length of line) to permit tracking when out of VHF range. 

No GPS data were lost, however, as the GPS fixes were recorded internally 

in memory as well as being broadcast over the VHF link . Typical 

deployments were for less than 48 hours with GPS sampling intervals of 15 

minutes . One drifter was deployed for nearly four days . 

Under light wind and calm sea conditions the Brightwaters Davis-type GPS 

drifter tended to maintain a fairly constant separation from the Technocean 

Davis-type ARGOS drifter . Under higher wind and sea conditions the 

Brightwaters drifter (which was larger and had greater surface exposure 

(See Figure 4 .3-3)) tended to lead the Technocean drifter and increased 

separation over time . Two of the Brightwaters drifters which had been 

deployed 0 .5 nautical miles apart at 1.5 and 2 .0 nautical miles from shore 

were found beached together . 

4 .3 .3 Technocean Davis-Type ARGOS Drifters 

Five of these drifters were provided by NllMS and supplemented the Nearshore 

Study deployments of Brightwaters drifters along the same onshore-offshore 

section . All five (see Table 4 .3-3) produced useful data . One drifter 

(14702) came ashore in heavy surf causing breakage of a couple of its sail 

support rods (see Figure 4 .3-4) . Otherwise, the drifters performed well 

and were easy to deploy and recover . The use of an ARGOS Direction Finder, 

also provided by MMS, was helpful in tracking down these drifters while 

offshore . Only the damaged 14702 drifter was recovered at the conclusion 

of the Nearshore Study . No attempt was made to pursue and recover the 

others though they were frequently tracked down and sighted during offshore 

operations . These drifters had less windage than the Brightwaters drifters

4 .4 Current Meter Data 

The instrument performance and data return for the three different types 

of current meters used in this program are presented in this section . The 

results are also broken down by mooring type (surface or subsurface) and 

are summarized in Table 4 .4-1 . The overall useful current meter data 

return for instrumented levels was 87 .1 (756,223 of 868,703 possible 

hourly records) for the entire program . The data return for all 

'recovered' instruments was 91 .3 . A total of 304 instrument deployments 

were made on 23 moorings at 51 levels . The 87 .1 data return includes the 

influence of the loss of thirteen of sixteen lost instruments, seven during 

the last three months of the study (See Table 4 .4-2) . Three of the lost 

instruments were backups and so are not counted in the instrument level 

data return percentage . Eight instruments were lost from six different 

moorings (three from surface moorings and five from subsurface moorings) 

at the B3 site and four were lost from three different moorings (two from 

surface moorings and two from a subsurface mooring) at the C3 site . These 

two sites accounted for 75$ of all instrument losses . None of the lost 

instruments have been recovered. The causes of these loses are discussed 

in Section 5 .2 . The data return was also affected by four instrument 

floodings, a number of other instrument malfunctions, and two mooring 

flotation failures which caused the loss of 'useful' data from parts of 

four current meter records (See Figure 4 .4-1) . 

Specifically excluded from all data return calculations are those 

locations/levels which were purposely not instrumented during parts of the 

two year field program. For example, the lower current meter level on the 

C1 surface mooring (an S4) was not instrumented during the last six months 

(August 1993 through February 1994) in order to provide a spare current 

meter for rotation into the surface moorings . In addition, the C3 surface 

mooring (with an S4 at 5 meters depth) was not deployed during the last six 

months of the program in order to provide a surface mooring for the B3 

site . Finally, the A5 subsurface mooring (with six current meter levels) 

was recovered early and not deployed for the last three months (November 

1993 through February 1994) in anticipation of unfavorable weather 

conditions for a February 1994 recovery . This mooring was located under 

the Gulf Stream in the extreme NE corner of the study area on the 3000m 

isobath . 

4 .4 .1 Aanderaa RCM-5/8s and RCM-8s 

As noted in Table 4 .4-1 the overall useful data return for the Aanderaa 

current meters was 93 .9 . Five of these instruments were deployed at the 

1900m and 2900m levels on the 2000m and 3000m Gulf Stream moorings . 

Aanderaa software communication problems (data downloading) were 

responsible for a small amount of data loss following the initial recovery 

of the instruments . This problem was detected but not understood during 

the initial downloading process at sea . Each time the Data Storage Unit 

(DSU) was downloaded, the file size stored on disk was a different length . 

Subsequently, three or four copies of each file were made before the DSUs 

were erased in preparation for the next deployment . Later, it was 

discovered that extra carriage returns were present in the tabular data . 

This required extensive post cruise editing in order to restore the data 

to its proper format . Some data could not be recovered, but because of the 

day/date time stamps in the data and the fact that each file downloading 

was intermittently scrambled and then not scrambled at different points in 

the record, fairly complete records were reassembled . A change to a

different computer along with infield confirmation of the proper data 

format prevented recurrence of the problem . 

Some data were also lost due to shorter than expected battery lives . 

Battery life for the new RCM-8s (serial numbers 10527, 10533 and 10535) was 

found to average 16 days less than for the RCM-5/8s (serial numbers 7528 

and 7582) at the 30 minute setting using the standard Leclanche' 

carbon/zinc battery (See Table 4 .4-3) . No data were lost, however, at one 

hour settings . The RCM-5/8s were originally RCM-5 mechanical reel-to-reel 

tape units that had been upgraded to DSU units . Apparently the battery 

drain on the newer RCM-8 units is greater than for the older upgraded 

instruments . 

4 .4 .2 InterOcean S4s 

As noted in Table 4 .4-1, the overall useful data return for the S4 current 

, ., meters was 81 .5 . Fourteen of these units were deployed on surface 

moorings . None were deployed on subsurface moorings . The two major 

contributors to overall data loss were nearly equally divided between 

instrument malfunctions and battery related problems (9 .5$) and instrument 

loss and flooding (9 .0$) . Six instruments were lost and one was flooded . 

The flooded instrument had a sheared off I/O connector. Instrument loses 

due to mooring failures are discussed in Section 5 .2 . Summaries of 

instrument performances, following each quarterly rotation, are presented 

in Tables 4 .4-4a through 4 .4-4h . 

All of the instruments were new, shipped directly from the manufacturer in 

December 1991 or January 1992 . As such, each had the most recent upgrades 

of firmware and hardware that InterOcean was providing . One unit had a bad 

compass and produced 'bad' current data during its initial deployment . 

Another unit lost the ability to store data internally nearly halfway 

through its first deployment . A third unit produced good data for only the 

first 40% of its second deployment . All other shortened data records (22 

in all) were caused by a number of instrument power related issues (power 

_-, failures) . Three of these power failures, however, occurred so close to 

instrument recovery that they had no significant impact on the data return . 

During the initial instrument recoveries (in April-May 1992 and in AugustSeptember 1992) thirteen instruments were recovered with two Power Failure 

flags and subsequently shortened data records . The range in data return 

was from 0% to 97% on these instruments . Twelve other instruments obtained 

100 data return, thereby indicating that the expected battery life was 

adequate for the deployments . These results were followed by a sequence 

of modifications and some investigative work by InterOcean, the results of 

which were significant . Only one of the 31 instruments deployed and 

recovered during the last three rotations of the field effort got less than 

1008 data return . 

Instrument modifications included replacement of the battery pack rings in 

.~ all of the instruments and the insertion of a foam pad on the underside of 

the battery pack ring . The purpose was to reduce up-and-down movement of 

the battery pack on the two battery posts (thought to be causing the power 

failures) . This was followed with the discovery that all instruments which 

had experienced power failures had potentially reduced the life of their 

respective CPU batteries . Indeed, some data were lost as a number of CPU 

batteries began dying prematurely . The fix was a modification to the 

] instrument's circuitry to prevent the CPU battery from attempting to

provide power to operate the instrument and to collect data when power 

failures occurred . The CPU batteries were normally expected to be good for 

at least three years . Another discovery was that Eveready alkaline 

batteries themselves could cause intermittent power failures . Eveready was 

in the process of converting from a high mercury content battery to a low 

or no mercury content battery . Their intermediate battery had the power 

failure characteristic and was used in some of the early battery packs 

during the first few deployments . The last three deployments used Duracell 

batteries only . 

One additional problem was identified and resolved . It had to do with wear 

on the titanium tension rod stopper ring which allowed the instrument to 

rotate on the tension rod but not move more than a quarter inch or so up 

--i and down . This ridge became worn and in some instances had worn to the 

point that the instrument could slide many inches up the rod and impact the 

attachment hardware . This caused external damage to the I/O connector and 

in one instance caused loss of the thermistor shroud . Obviously, this 

also enhanced the upward and downward momentum of the instrument's internal 

power pack . The problem was resolved by replacing the worn tension rods 

and installing nylon washers in the quarter inch space under the stopper 

ring . 

9 .4 .3 General Oceanics Mkls and Mk2s 

The overall useful data return for the General Oceanics current meters was 

88 .48 . This is the composite data return from 183 of 186 deployments 

identified in Table 4 .4-1 . This percentage includes the influence of seven 

instruments that were lost and three that were flooded producing no data . 

Interestingly, this is the only type instrument that produced 100$ data 

return at any of the 51 instrumented levels . Twelve levels instrumented 

with General Oceanics current meters produced a 100$ useful data return for 

1 the entire two-year study period . 

Three instrument losses were clearly associated with mooring wire failure 

(1) and premature release activation (2) . Four loses are unexplained but 

are suspected to be due to premature release activation or interference 

from other offshore interests . One instrument was lost as its orange 

swivel attachment ring failed and two other standoffs with instruments 

either disintegrated in high currents (from strumming) or were struck and 

torn from their moorings by other offshore interests . Six of the ten loses 

were from four moorings at the B3 site and three were from two moorings at 

the C3 site (see Table 4 .4-2) . The three flooded instruments were all 

equipped with pressure sensors which apparently leaked . Two of the 

instruments were rebuilt at no charge by the manufacturer . The clock 

batteries on three of the older cassette drive instruments died during the 

.,, first year of the deep mooring deployments and two of 22 new RAM cartridge 

units failed to collect complete data records during their initial threemonth deployments . One of these RAM cartridge units also produced 

questionable directional data (off by about 45°) and an older cassette 

drive unit had an intermittent sticking problem with its tilt sensor . None 

of the instruments experienced 'main' battery problems .

V . MOORING PERFORMANCE AND DAMAGE 

5 .1 Introduction 

This section reviews the technical aspects of the current meter mooring 

effort with respect to surface and subsurface mooring survivability and 

surface buoy damage . In addition, since NlNiS required that the moorings be 

designed to implement mooring anchor recovery, the results of these efforts 

are also summarized . 

5 .2 Mooring Failure and Instrument Loses 

5 .2 .1 Wire Failure 

Six mooring wire failures were experienced over the course of the two year 

field program. Four of these were associated with surface moorings on the 

shelf and two were at or near the tops of 2000 m and 3000 m Gulf Stream 

moorings . Four instrument loses (one Mk2 and three S4s) were attributed 

to these failures . The initial wire failure occurred at the A3 surface 

mooring site when the wire parted under tension while relocating the 

mooring anchor during a quarterly servicing . This failure was clearly due 

to overloading the cable . The second and third failures occurred on 

surface moorings at the C3 and B3 sites . Both failures appear to be the 

result of sudden wire overloads . The next failure occurred near the top 

of the A5 3000 m subsurface Gulf Stream mooring . Crevice corrosion had 

occurred at a Vel Lock swivel attachment point . Crevice corrosion was also 

responsible for wire failure at the C2 surface mooring site . Here, over 

time, a cut or slice in the Nil Spin wire coating had become an active site 

for corrosion. Finally, wire failure occurred just below the Nicropress 

termination of the upper float on the C4 2000 m Gulf Stream subsurface 

mooring. Repeated bending under load just below the termination, and wire 

corrosion appear to be responsible . These wire failures are summarized 

in Table 5.2-1 . Further discussion of some of these failures is provided 

below from Paul Higley of Specialty Devices, Inc. He examined samples from 

four of the failures (C4, C2, A5 and B3) . 

C4 : C4 is 1/4" 3x19 wire with Quiet Cable jacket that had been terminated 

with an SDI cast-on zinc termination . The failure on this wire occurred 

at the termination . The wires show two contributing causes of the failure, 

sharp bending under load at the termination and corrosion of the outer 

strands of the wire construction . The strands on one side of the wire at 

the entrance to the termination failed at a slightly different length from 

the strands on the other side of the wire . Judging by the zinc mold 

imprint in the wire jacket, the wire was loaded heavily while the wire was 

bent at the termination . I suspect this occurred during deployment or 

retrieval as the wire was taut to the winch and the steel float was over 

the side . Neither cause was solely responsible for the failure . The 

corrosion was significant on the wire and would have caused a failure 

regardless of the bending . The fact that the bending can be seen is 

however reason to address it . The small wire is more subject to both 

bending stress and corrosion . Some form of limitation to the bend radius 

in the wire at the termination or procedural change to prevent this kinking 

would also help . I will look into changing the mold to provide a stress 

relief at the termination . In defense of the cast on terminations, the 

zinc probably slowed down the onset of the corrosion significantly and any 

other termination without the zinc addition may have failed earlier given 

95

during the NC Field Program.

the same conditions . We should probably not try 1/?" wire for mooring 

deployments beyond 18 months in deployments that have frequent servicing 

where we will likely damage the wire jacket . 1/9" wipe has been used for 

deployments for these long periods but the moorings were installed 

carefully once with care taken not to damage the jacket . Large wire or 

shorter replacement cycles and some way to prevent the sharp bend at the 

termination would help . 

C2 and A5 : C2 is 3/8" Nilspin and A5 is 5/16" Quiet Cable . Both of these 

wires appear to have failed during high stress loading at places where the 

wire jacket was pierced and the wire weakened due to corrosion . C2 appears 

to be a jacket that was cut either during handling or while deployed . The 

A5 jacket was probably melted through in the process of installing the 

swivel for the wire fairing. Since it is nearly impossible to prevent some 

abrasion or cuts in the wire jacket during a long field program with many 

redeployments, the cure for this type of failure is to replace the wire 

more often or use larger wire . In both cases I would lean towards more 

frequent wire replacement rather than larger wire diameter (personal 

preference) . 

B3 : B3 is 3/8" Nilspin from a Catamaran buoy mooring. This failure is 

more interesting than the others . In this case the strands of the wire are 

not significantly corroded as in the other three wires . The jacket is also 

distorted and appears to have experienced two different forms of damage . 

One jacket damage area is a nearly uniform wear to the jacket all the way 

around the wire . I suspect that this occurred during deployments or 

retrievals as the Catamaran buoy was towed and the wire was wearing on the 

deck . This did not contribute to the failure but in the future may have 

lead to a failure due to corrosion. 

At the failure point, the jacket is split in three places nearly along the 

axis of the wire . It appears that these wire splits are the result of an 

extreme sudden loading on the wire that caused the wires to explode outward 

as they failed . The ends of the wire strands support this failure as they 

are sharp angle shear failure consistent with exceeding the breaking 

strength of the wire . The wire jacket is also distorted along the length 

of the sample section . This would suggest that one or two of the three 

bundles failed first and the remaining bundle elongated as it tried to 

carry the load until it also failed . This loading of one bundle out of the 

three would cause it to try to be straight and the others to try to move 

out of the way . This is supported by the different failure point of some 

of the strands of one bundle versus the failure point of all strands in the 

other two bundles . To conclude, this failure looks like high sudden shock 

loading to the wire that exceeded the breaking strength . 

5 .2 .2 Shackle Failure 

Shackle failures occurred at the B3 and D1 surface mooring sites sometime 

after the November 1993 rotation cruise and prior to the February 1994 

recovery cruise . Two S4 current meters were lost from these sites . Both 

moorings had been serviced in August 1993 and observed on station in 

November 1993, but were not serviced at that time due to weather at the Dl 

site and weather and strong currents at the B3 site . A 5/8" shackle 

joining two lengths of 3/4" chain appears to have been responsible for the 

failure . One severely corroded safety anchor shackle with no nut (but with 

its cotter pin in place) was recovered . It had been attached to another 

shackle which was attached to more chain which ran to the surface buoy . 

97 
The severe corrosion is suggestive of an electrolysis problem. Efforts to 

duplicate the problem with spare shackles in the lab have been 

unsuccessful . 

J 5 .2 .3 Premature Release Activation 

one subsurface mooring at the B3 site was lost with two Mk2 current meters, 

apparently due to premature release activation . The Benthos acoustic 

release had been checked and tested on deck prior to deployment . Battery 

power was checked and more than adequate battery life was available for the 

deployment . The release was interrogated after deployment and responded 

without incident . It was also equipped with a rope canister to implement 

anchor recovery . 

The unit did not respond to interrogation or come to the surface during 

subsequent recovery efforts beginning three months after deployment . 

However, the anchor was later recovered complete with chain, the release 

link that went to the release, and all of the rope that had been in the 

rope canister . The end of the rope, which had been attached to the 

release, had chafed through. Clearly, this particular release had been 

activated either by an instrument malfunction or other acoustic activity 

in the area . Care had been taken, however, to avoid inadvertently 

activating releases by arranging the release codes throughout the study 

area in a way to prevent any possibility of activation while at adjacent 

mooring sites . 

5 .2 .4 Unexplained Disappearances 

Unexplained disappearances are attributed to the loss of five other 

instruments . Four GO Mk2 current meters were lost from two additional 

subsurface moorings at the B3 and C3 sites . Premature release activation 

' seems the most likely explanation but no anchors were recovered to verify 

that scenario . However, as for the verified release activation loss, both 

mooring releases were tested prior to and following deployment and had 

adequate battery life, but did not respond on interrogation three months 

after deployment . Grapnel efforts were unsuccessful but did strike 

'something' (possibly the anchor) on the bottom where the moorings were 

expected to be . Finally, the A2 surface mooring disappeared without a 

- ., trace in spite of an extensive grapnel effort and surface area search . No 

,-~ sign of this mooring was ever detected . One S4 current meter was lost from 

this site . 

5 .3 Surface Buoy Damage 

Most of the significant buoy damage on the surface moorings was related to 

damaged or destroyed lights . Four lights were damaged or destroyed early 

in the field program during can buoy mooring rotations (at the A2, B1 and 

B2 sites) aboard the R/V CAPE HENLOPEN (See Table 5 .3-1) . This was 

primarily due to lights impacting the stern of the vessel during 

recoveries . This problem was later eliminated with a specially designed 

lamp protector which was fitted over the lamp before recovery was 

attempted . Five other buoy lights (at A1, A2 twice, C3 and D1) were found 

damaged or destroyed over the course of the field effort and the A3 buoy 

had a large chunk of foam missing from its side and from its radar 

reflector in November 1993 . The light was undamaged .

99 
5 .4 Shelf Anchor Recoveries 

one aspect of mooring design that was required by 3-MS was a means of 

recovering the shelf mooring anchors . This was implemented by the use of 

rope canisters on the eight shelf subsurface moorings . A total of 57 

subsurface mooring anchors were recovered and five were lost for a 

' subsurface mooring anchor recovery rate of 91 .9 . In turn, sixty-nine 

surface mooring anchors were recovered and four were lost for a surface 

mooring anchor recovery rate of 94 .5 . Table 5 .4-1 summarizes the anchor 

loses . Eleven of the recovered anchors from the A1(1), A2(3), B1(2), B2(3) 

and C2(2) sites were found to have been totally buried . In addition, it 

is suspected that anchor burial contributed to the three anchor losses 

which occurred at the B1(2) and B2 (1) sites . Most anchor burials were 

observed during the February and May anchor recovery efforts .

VI . INSTRUMENT FOULING AND ANIMAL OBSERVATIONS 

6 .1 Introduction 

Fouling of each shelf instrument recovered during the two year field effort 

was documented . Photographs of most instruments were taken (prior to 

cleanup) beginning with the second recoveries in August and September 1992 . 

Two types of fouling are reported on : biological and non-biological . Nonbiological fouling consisted of longline, mooring fairing, fishing line and 

rope fouling about the affected instrument . Since no significant fouling 

was observed on any of the deep moorings (A4, A5, B4 and C4) except for 

mooring fairing having wrapped around the swivel area of one Mk2 current 

meter (which also flooded), no discussion is presented for the deep mooring 

instruments . 

6 .2 Biological Fouling of Instrumentation 

No significant biological fouling other than a thin green film was observed 

on any of the deep mooring instruments at the A4, A5, B4 and C4 sites . 

These incidences were restricted to the upper current meter at each site . 

Varying degrees and types of fouling, however, were observed on the shelf 

mooring instruments . No antifouling compounds were used . Tables 6 .2-1 and 

6 .2-2 summarize the observed fouling on the S4s and Mk2s, respectively . 

A few trends are discernable in the S4 fouling data presented in Table 6 .2-

1 . The heaviest fouling was observed during the November 1992 rotation and 

the least fouling was observed during the May 1993 rotation . Except for 

the February 1994 recovery, the instrument on the A3 surface mooring 

appears to have experienced the least amount of fouling over the study 

period . Gooseneck barnacles were not observed on instruments on the 20 

meter isobath at the A1, B1 and C1 sites . Figure 6 .2-1 shows examples of 

some of the observed fouling on the S4 current meters . 

The Mk2 current meters were only deployed in the 

where water depths were 35 meters and 60 meter 

barnacles were observed on any of the instrument 

A3 sites), and none were observed on any of th 

February and May 1993 . Barnacle deposits were 

November 1992, August 1993 and November 1993 

shows examples of some of the observed fouling 

6 .3 Non-Biological Fouling of Instrumentation 

mid to outer shelf region 

s depth, respectively . No 

s along Line A (the A2 and 

e instruments recovered in 

e most prolific during the 

recoveries . Figure 6 .2-2 

on the Mk2 current meters . 

Table 6 .3-1 summarizes the eleven incidences of non-biological fouling 

observed during the field effort . Except for fishing line fouling observed 

at the C2-surface mooring site (on the 35 meter isobath) in November 1992, 

all other incidences occurred at moorings along the 60 meter isobath . 

Longline fouling was found in both February 1993 and February 1994 at the 

A3 site and in February 1994 at the D2 mooring site . All other foulings 

but one were likely related to other fishing activities where small lengths 

of rope or snarls of fishing line were found wrapped about the tension rod 

of the S4 current meter . These were observed in May, August, September and 

November 1992 and in August 1993 .

6 .4 Animal observations at Mooring Sites 

Early on, it became obvious that the mooring anchors had become habitats 

for a number of types of marine life . Beginning with the February 1993 

mooring rotations, site specific observations were recorded for marine life 

when observed (See Table 6 .4-1) . Prior to that time, the same types of 

marine life (particularly octopi and black sea bass) had been observed 

during each cruise, but no effort had been made to document the locations . 

Octopi were observed only south of Cape Hatteras at the Line C mooring 

sites (C1, C2 and C3) and black sea bass, eels and crabs were observed only 

north of Cape Hatteras at the A3, D1 and D2 sites . Both octopi and black 

sea bass were observed, however, at the Hatteras Corner (B3) site . Over 

80 black sea bass were recovered from the A3 surface mooring anchor in May 

1993 . The anchor had been deployed for six months . 

Other site specific observations included, a shark tooth found embedded in 

a General Oceanics current meter wing at the B3 site in November 1993, a 

school of cobia swimming around the A1 surface buoy in August 1993 and a 

leather back turtle observed at the B3 site in November 1993 .

VII . DATA ARCHIVING 

7 .1 Introduction 

All of the CTD, ARGOS and GPS drifter, and current meter data have been 

processed and submitted to NODC . The assigned NODC Project Identification 

Number for all three types of data is 0208 . The particulars of each type 

of data submittal are presented below. 

7 .2 Data Submitted to NODC

7 .2 .3 Current Meter Data 

When the processing of each current meter data set was completed at the end 

of each mooring rotation, an interim submission was made to NODC using 

Format F-015 and the unique NODC project number 0208 . Due to the large 

number of instruments that were recovered later than the rest of their 

respective deployments and the data which required special processing, a 

final submission including data from the entire program and superseding all 

previous submissions was made on May 11, 1994 . Table 7 .2-1(a-f) presents 

a compilation of all of the current meter raw data files (by name) which 

were submitted .

The Department of the Interior Mission

As the Nation's principal conservation agency, the Department of the Interior has responsibility 

for most of our nationally owned public lands and natural resources. This includes fostering 

sound use of our land and water resources; protecting our fish, wildlife, and biological diversity; 

preserving the environmental and cultural values of our national parks and historical places; 

and providing for the enjoyment of life through outdoor recreation. The Department assesses 

our energy and mineral resources and works to ensure that their development is in the best 

interests of all our people by encouraging stewardship and citizen participation in their care. 

The Department also has a major responsibility for American Indian reservation communities 

and for people who live in island territories under U.S. administration. 

The Minerals Management Service Mission 

As a bureau of the Department of the Interior, the Minerals Management Service's (MMS) 

primary responsibilities are to manage the mineral resources located on the Nation's Outer 

Continental Shelf (OCS), collect revenue from the Federal OCS and onshore Federal and Indian 

lands, and distribute those revenues. 

Moreover, in working to meet its responsibilities, the Offshore Minerals Management Program 

administers the OCS competitive leasing program and oversees the safe and environmentally 

sound exploration and production of our Nation's offshore natural gas, oil and other mineral 

resources. The MMS Minerals Revenue Management meets its responsibilities by ensuring the 

efficient, timely and accurate collection and disbursement of revenue from mineral leasing and 

production due to Indian tribes and allottees, States and the U.S. Treasury. 

The MMS strives to fulfill its responsibilities through the general guiding principles of: (1) being 

responsive to the public's concerns and interests by maintaining a dialogue with all potentially 

affected parties and (2) carrying out its programs with an emphasis on working to enhance the 

quality of life for all Americans by lending MMS assistance and expertise to economic 

development and environmental protection.
