SUBJECT: Update on DataBases Available from the Marine Sciences
Section (MSS)

The purpose of this memo is to update my memo of March 1, 1993, which
documents the current and historic data bases in the Marine Sciences
Section computers.  These databases include:

1. Harbor Survey data collected from 1968-1993.  Data from 1909-1967
are being computerized under a HEP grant and will be included by
fall, 1994.  
2. Metals Wasteload Allocation sediment, ambient water, CSO
   and WPCP effluent from 1991-1992.  
3. Long Island Sound Study (LISS)
   Ambient Nutrients for the East  River and entire LIS from October,
   1988 - December, 1993.  
4. TSS/VSS data collected daily (except weekends and holidays) 
   from the Hudson River from the North River WPCP since November, 1991.  
5. East River Tributary Sampling from 1992-1993.  
6. NY Bight Hypoxia cruises from 1991-1993.  
7. Jamaica Bay CSO Study Ambient Data from 1988.  
8. East River CSO Study Ambient and Point Source Data from 1988-1989.  
9. NYC WPCP flow and influent, effluent data for metals and
   nutrients  for January, 1985 through January, 1994 and July, 1982
   through January, 1994, respectively.  Sludge metal data are also
   included.  All the databases are available and ready to be used.  They are
   on either ASCII files or spreadsheets in the MSS Network under F:\MSSDATA.
   The data are 'raw', i.e. as measured, and not averaged.  Documentation of
   the expanded Plankton data-base for 1992 will follow.  cc:

METHODS
				   A.  Sampling - NYCDEP personnel sampled
				   surface and bottom waters at each of 52
				   stations (Attachment 2) approximately
				   once every other week (8-12 times, June
				   - September).  Additional year-round
				   sampling for most parameters has been
				   performed since October, 1990.  Unless
				   noted otherwise, all methods conformed
				   to Standard Methods for the Examination
				   of Water and Wastewater.  A historical
				   summary of analyses conducted by the
				   Harbor Survey since 1909, is presented
				   in Attachment 1.

Water samples were collected from onboard the HSV Osprey, an
aluminum-hulled 55 foot twin-engine diesel craft.  Stations are located in
the field by latitude-longitude and line-of-site from station descriptions
in Attachment 2.  Note that past typographical errors for some of these
descriptions and coordinates have recently been corrected.

Water samples were collected from surface waters (1 meter below the water
surface) and bottom waters (1 meter above the sediment surface) using a 3.2
liter Kemmerer sampler.  After July 1992, bottom samples were collected
using a 5.0 liter Teflon-lined Niskin sampler.

B.  Total and Fecal Coliform - The multiple tube fermentation technique for
total coliform bacteria was begun onboard by aseptically inoculating five
tubes of lauryl tryptose broth in three serial decimal dilution portions
for a total of 3 x 5 = 15 tubes per sample. The sample water dilutions used
depended on expected coliform concentrations for each station; greater
dilutions were used following rain events.  The tubes were immediately
incubated on board at 35C.  After docking, they were transported to the
Wards Island (WI) laboratory for continued incubation.  The presumptive
test was followed by the confirmed test using brilliant green bile media.
Data were reported as the most probable number of coliform per 100 ml
(MPN/100 ml).  Blank and duplicate analyses were performed daily as part of
the quality assurance/quality control (QA/QC) program, as per Standard
Methods.

The membrane filter (MF) technique has been used to determine fecal
coliform concentrations in Harbor waters since 1974.  Prior to 1985, daily
surface and bottom water samples at each site were composite; since 1985,
surface and bottom samples have been analyzed separately.  Samples were
aseptically filtered on-board through 0.45 micron membrane filters with the
aid of a vacuum pump.  The amount of sample filtered depended on expected
fecal coliform concentrations.  The membrane was aseptically removed from
the filter holder and placed into a 47 mm petri dish containing M-FC
media.  Petri dishes were immediately placed in portable incubators at
44.5oC for 24  2 hours of incubation.  The appropriate colonies were then
counted and reported as number of fecal coliform/100 ml.  Blank and
duplicate analyses were performed daily as part of the QA/QC program.

C.  Temperature, Salinity, and Density - In 1991, temperature, salinity,
and density profiles of the water column at each station were obtained
using a Seabird Seacat (SBE 19) CTD. Starting in June 1992, these
measurements were typically performed using a Sea-Bird SBE 25-03 Sealogger
CTD.  This instrument is capable of taking two readings per second of
conductivity and temperature.  Software supplied by the manufacturer
enables the calculation of salinity from these values.  The instrument is
also configured with other sensors including a fluorometer, a 10cm
pathlength transmissometer, and a polarographic dissolved oxygen sensor,
all also capable of collecting data twice a second.  These data are then
used to generate a profile for each parameter down through the entire water
column (to within one meter of the bottom) at each sampling station.
Duplicate analyses were performed at one random station per day.  When the
CTD was unavailable, a Labcomp SCT meter was used for salinity and
temperature readings only.

D.  Dissolved Oxygen (DO) - From 1909 to 1984, DO was determined onboard
using the azide modification of the Winkler method.  From 1985 through
1987, YSI DO meters were often used.  These DO meters were calibrated and
rechecked two or three times each sampling day using the azide modification
of the Winkler method.  From 1988 through 1992, the Winkler method was once
again used almost exclusively.  Duplicates were analyzed at one random
station per day.  Reagents are changed at regular intervals.

E.  Biological Oxygen Demand (BOD) - Samples for BOD analysis were
collected in clean 1 liter polypropylene bottles, cooled to 4oC, and
delivered to the Oakwood Beach Process Control Lab for unseeded 5-Day BOD
analysis which included sample reaeration, and incubation at 20oC for five
days.

F.  Nutrients - Samples for nutrients (total phosphorus, and the dissolved
fractions of orthophosphate, ammonium, and nitrate-nitrite combined) were
determined from twice monthly surface samples.  Total phosphorus samples
were placed directly in sample-rinsed 125 ml polypropylene bottles,
refrigerated at 4oC, acidified with sulfuric acid to pH <2,  and then
placed in coolers for transport back to the Wards Island laboratory.  For
ammonium, nitrate-nitrite, and ortho- phosphate, 250 ml samples were
immediately filtered on-board through pre-rinsed 0.45 micron membrane
filters, placed in 250 ml bottles, refrigerated, preserved with sulfuric
acid, and put in  coolers for transport back to the lab.  Prior to 1989,
nutrient concentrations were measured using a Technicon Auto Analyzer II
according to Methods for Chemical Analysis of Water and Wastes.  Since
1989, a TRAACS 800 using the modified Industrial Method has been used.  For
a comparison of LISS/NYCDEP split-sampling results, see pages Q12-Q13 in
Harbor Survey Report 1991-1992.

G.  Chlorophyll 'a' and Plankton - Chlorophyll 'a' and plankton samples
were collected from surface waters  with the nutrient samples.  Chlorophyll
'a' was determined fluorometrically following on-board

			  Attach 3 (cont.2/7)

filtration of 250 ml through 0.45 micron membrane filters, and extraction
in aqueous acetone, as detailed in Standard Methods.  For plankton
analyses, 0.8 L of surface water was collected monthly from each station.
5.6 ml of Lugol's solution was added to each sample in one liter glass
beakers and samples were allowed to settle for 48 hours.  After settling,
the supernatant was siphoned off, concentrating the sample to a final
volume of 100 ml.  A portion of the concentrated sample was stored in a
clean glass screw cap vial for future plankton analysis by the Oakwood
Beach Lab.

A Sedgewick-Rafter cell was used for plankton counting.  This cell is 50 mm
long by 20 mm wide by 1 mm deep giving it a volume of 1 ml.  A calibrated
Zeiss Photomicroscope III equipped with a Whipple ocular micrometer was
used to identify and count all plankton cells contained in the 1 ml of
concentrated sample in the S-R counting cell.  Ten or twenty random Whipple
disc fields at magnifications of 125x,  200x and 320x were counted for the
more abundant forms.  Concentrations of rare forms were estimated by 'strip
counts' or by 'survey counts'.  Calculations and methods were performed
according to Standard Methods.

H.  Total Suspended Solids (TSS) - Samples for TSS analysis were collected
once at surface and bottom waters of each station in November and December
of 1990, and thereafter bi-monthly year-round through 1992. TSS was
determined from filtration of 250 ml samples through pre-weighed Whatman
GFF 934AH filters tared in crucibles, as per Standard Methods.

I.  Secchi Transparency - Transparency of surface waters was estimated
using a standard black and white quadrant Secchi disk, as per Standard
Methods.  Measurements were recorded to the nearest one-half foot.

J.  pH - pH measurements were performed on surface and bottom waters of
each site on the boat immediately after sample collection.  pH meters used
included a Cole-Parmer pH Vision 6009, and an Orion 250A, with integrated
temperature probe.  pH meters were calibrated daily with fresh standards.

K.  Tidal Cycle Studies - Special tidal cycle studies included analyses of
DO, temperature, salinity, total coliform, TSS, and chlorophyll 'a'
concentrations for 12 hours (~6 am to ~6 pm) during an ebb and flood tidal
cycle at each of the three limits of the harbor: the Hudson River at Mount
St. Vincent, the East River at Throgs Neck, and the Narrows in New York Bay
in 1991 and 1992.  Samples were collected from the surface and bottom on
each side of the waterway and in midstream every hour, except for coliform,
TSS, and chlorophyll 'a', which were sampled every other hour.

L. Trace Metals in NY/NJ Harbor Waters and Sediment

i) Metals in the Water Column - As part of data collection activities for
the metals waste load allocation (WLA) modeling effort of the NY/NJ Harbor
Estuary Program (HEP), water column and sediment metals

samples were analyzed.  Water column metals sampling was performed by U.S.
EPA and Battelle Ocean Sciences (Duxbury, MA) in January and May of 1991,
and by NYCDEP and Battelle in October 1991.  Methods for metals sampling,
handling, and analysis were appropriate for measurements of trace metals in
estuarine waters.  Samples were collected with acid-washed, Teflon-lined
Go-Flo sampling bottles.  Sample preservation and filtration (for dissolved
samples) were immediately performed on board.  All metals and associated
laboratory measurements were performed by Battelle.  All metals samples,
except mercury, were extracted by a solvent-solvent extraction before
analysis by graphite furnace atomic-absorption spectroscopy; mercury
samples were analyzed by gold amalgamation.  Sample handling, and analysis
are presented in flow charts on page K5; full details are provided in the
quality assurance plan.

Water column metals samples were collected at sites throughout the estuary
in 1991 during January (representing a high river flow/high TSS period),
May (tidal cycle sampling), and October 1991 (low river flow/low TSS
period).  Sampling sites differ from regular Harbor Survey sites (pp.
K1-K4).  Sampling logistics are presented below.

  present, sampled at mid-depth.  b All six sites sampled at upper
  one-quarter and lower three   quarters of the water column at
  ebb, low, flood, and high tide.  c Forms of metals measured in January
  included total recoverable,   acid soluble, particulate and
  dissolved.  In May, acid soluble was   omitted; in October, acid
  soluble and particulate were omitted.

ii)  Metals, Toxicity, and Associated Measurements in Sediments - The U.S.
EPA, NYCDEP, and Battelle also collected sediment samples at 20 stations
throughout the estuary over four days during February, 1992 (pp. K1-K4).
Sampling locations included sites throughout the Harbor, Bight Apex,
Jamaica Bay, Newark Bay, the Passaic, Hackensack, upstream Hudson, and
western Long Island Sound (WLIS).  Parameters measured in the bulk surface
sediments included: sediment toxicity, acid volatile sulfides (AVS),
simultaneously extracted metals (SEM), bulk sediment metal concentrations,
grain size, total organic carbon (TOC), pH, and

			  Attach 3 (cont.4/7)
redox potential.  In addition, porewater measurements included salinity,
dissolved organic carbon (DOC), dissolved sulfide (as H2S), ammonium, and
metals concentrations.  Metals measured in SEM, bulk sediments, and
porewaters included silver (Ag), arsenic (As), cadmium (Cd), copper (Cu),
mercury (Hg), lead (Pb), nickel (Ni), and zinc (Zn).

Clean techniques appropriate for the collection of trace metals were used
throughout the study.  Test procedures are briefly described below.  Full
details please see Harbor Survey Report 1991-1992.

Of the twenty surficial (i.e., upper 5 cm) sediment samples, seventeen were
collected from the U.S. EPA's R/V Anderson using a box corer.  The three
remaining samples (at sites E3, A8, and A9) were collected from the U.S.
EPA's R/V Clean Waters, using both Smith-MacIntyre and Ponar sediment
grabs.  Sample processing is displayed on page L1.  The sediment samples
were processed under nitrogen to prevent oxidation of the AVS.  Acute
toxicity of bedded sediment was conducted over a ten day period using a
solid phase, flow-through method with the amphipod, Ampelisca abdita, as
the test organism.  A 96-hour static test was also performed using cadmium
chloride (CdCl) as the reference toxicant to test the relative sensitivity
of the test organisms.

SEM/AVS were determined using the colorimetric method of Allen et al.
(1991).  Samples for metals in bulk sediments were digested using an aqua
regia acid solution and heating with a microwave oven in a closed Teflon
digestion vessel.  The solution was then diluted and analyzed with furnace
and flame atomic absorption techniques for all metals except mercury, which
was measured using cold vapor atomic absorption procedures.  Porewaters
were extracted by centrifugation, and all metals (except mercury) were
analyzed using graphite furnace atomic absorption. Mercury pore water
concentrations were determined using cold vapor atomic fluorescence.  Five
of the porewater metals (Ag, Cd, Cu, Ni, and Pb) required a chelation step
to concentrate the metal and reduce interferences.

M.  Volatile Organic Compounds (VOCs) - Surface and bottom water samples
were collected twice from each station for analysis of selected purgeable,
volatile, organic priority pollutants (VOCs), using U.S. EPA Test Method
624.  Samples were collected using Kemmerer samplers from the front of the
boat and transferred to 125 ml glass vials filled to overflowing to exclude
air bubbles.  A purge and trap device was attached to a Hewlett-Packard Gas
Chromatograph Mass Spectrophotometer electronic data system, and run in the
select ion mode.

N.  Special Studies

i) Long Island Sound Study (LISS) - The LISS is a six year federally-funded
research and management program whose goals are to identify the major
environmental problems of the Sound, and to develop a Comprehensive
Conservation and Management Plan by 1994.  The Harbor

			  Attach 3 (cont.5/7)

Survey Program has been expanded since 1988 to provide additional data for
this program (see Nutrients section).

ii) NY Bight Hypoxia Monitoring - In response to concerns that unusually
warm temperatures in late spring 1991 might cause severe hypoxia in the NY
Bight, three monitoring cruises were conducted jointly with the Waste
Management Institute of the University of New York at Stony Brook during
summer 1991.  A fourth cruise was performed in August, 1992.

iii) East River Tributaries - Harbor Survey monitoring was expanded to
tributaries of the East River to gather baseline ambient water quality data
in support of NYC's involvement in the LISS, and CSO Abatement Program.
Monitoring of three sites on the Bronx River and one site on Westchester
Creek was performed from April through September, 1992.

iv) Fresh Creek Sampling (Jamaica Bay) - In anticipation of the expansion
of a prototype combined sewer overflow (CSO) abatement facility, baseline
sampling was performed eight times from July through November, 1991.

v) Daily TSS and volatile suspended solids (VSS) Monitoring of the Hudson
River - In an effort to provide additional data to help characterize the
variability of TSS in the Hudson, a daily surface sample of Hudson River
water has been collected from the dock of the North River Water Pollution
Control Plant since late 1991.  Data are available upon request from the
Marine Sciences Section.

O.  Statistical Analysis and Data Presentation - Long-term linear trends
were quantified using the Statistical Analysis System (SAS).  Trends were
evaluated by computing Pearson product-moment correlations at a
significance level of p < 0.05, unless noted otherwise; datasets which did
not display normal distributions (e.g., coliform and metals) were
log-transformed prior to trend analysis.  Other statistical determinations
(regression, factor and discriminant analyses) included careful analysis of
the assumptions of each statistical test.  Minor deviations and
modifications are noted where relevant.

Special note with respect to Concentration Distribution Maps: these maps
are used to depict areas of high and low concentration relative to the rest
of the Harbor.  Concentration gradients on most maps (except DO and
coliform) are delineated by quartiles which assign four levels of shading
based upon 25th percentiles.  For example, on page D1, the 13 lowest
average concentration sites for salinity are shown as black (13/52 = 25%).
Note that these concentrations are really site specific, and extrapolation
to other areas depicted on these maps may not be valid, and should be
interpreted with caution.  Note also that maps and especially waterways are
not necessarily drawn to scale.

All figures and tables are in Appendices A through Q at the back of the
Harbor Survey Report 1991 - 1992.  Selected figures and tables are also
presented in the main body of the report.

analysis of duplicate, spike, and blank samples; replicated and documented
calibrations of meters; and comparison of results between analysts.
