ABSTRACT 

A field program designed to measure the ambient concentration of SOZ as well 

as pertinent meteorological parameters was conducted during the summer of 1993 . 

Three stations were established in the EPA Class I area of Breton Refuge and the 

Class II Delta Wildlife Refuge near the mouth of the Mississippi River . It was found 

that the S02 concentration measured throughout the monitoring duration was only 2% 

of the National maximum allowable once per year . The passage of a weak cold front 

in September showed that the S02 concentrations were higher when the wind blew 

from land to the Gulf than under normal summer conditions when the wind blew from 

the Gulf toward land . A separate analysis of atmospheric profiles over the Gulf of 

Mexico determined that the average mixing height was about 670 m, lower than 

expected for the region . Further studies are recommended to separate the 

contributions of pollutants from offshore areas vs . land sources and to more 

thoroughly document the variations in mixing height for modeling purposes .

EXECUTIVE SUMMARY 
EXECUTIVE SUMMARY 

The coastal regions of Louisiana, Mississippi, and Alabama have been well 

documented for their rich and diverse wildlife and fisheries, and for the natural 

beauty of the marshlands, islands, and beaches. In order to preserve these 

environments, two National Wildlife Refuges were established ; the Delta Refuge at 

the mouth of the Mississippi River, and the Breton National Wildlife Refuge which 

encompasses most of the Chandeleur Island chain . The Gulf Islands National 

Seashore includes the coastlines of Mississippi and Alabama as well as their barrier 

islands . 

Offshore energy exploration and production in the Gulf of Mexico has become 

increasingly active in the coastal waters to the east and south of these National 

preserves . Atmospheric emissions of pollutants such as SO,, HAS, HZSO and nitrous 

oxides are a necessary by-product of energy platform operation . Pollutants are also 

emitted from mainland facilities such as ports, refineries, and power plants . The 

most recent Clean Air Act designates numerous National parks and refuges as Class 

I, thereby subjecting them to the Prevention of Significant Deterioration (PSD) 

doctrine . Within Class I areas, the air quality must meet established National 

"increments" for pollutant concentrations . 

In response to environmental concerns in the Breton National Wildlife Refuge, 

the Coastal Studies Institute (CSI) of Louisiana State University entered into an 

agreement with the Minerals Management Service, New Orleans . The objective of 

the agreement was to provide measurements of S02 concentration in the Delta and 

Breton Wildlife Refuges and to analyze the structure of the marine atmosphere over 

these areas . The extent to which atmospheric pollutants from offshore energy 

production and mainland facilities was affecting the refuges could then be 

determined . 

The summer months of July, August, and September 1993 were chosen for study 

due to the greater frequency of high pressure systems over the area . Air stagnation 

associated with the high centers generally leads to higher pollution concentrations . 

Two offshore stations were established by CSI in late July . The first was on Gosier 

Island and the second on a moored vessel near Breton Island, both within the Breton 

National Wildlife Refuge (see Fig. 1) . Environmental Science and Engineering, Inc . 

(ESE) was subcontracted to install and maintain a third station at the headquarters 

complex in the Pass-A-Loutre Wildlife Area south of Venice, Louisiana . At these 

three sites, ambient S02 concentrations were measured along with wind speed and 

direction and air temperature . 

The data record from each site revealed that the average daily SOZ concentration was well below the maximum 24-hour National Ambient Air Quality Standard 

during the monitoring period . The passage of an early season cold front in September 

provided an interesting study . When the wind blew from the mainland toward the 

Gulf (post-frontal), the SOZ concentrations were higher than under normal 

conditions, i .e ., when the wind blew from the Gulf to land . 

A separate field project, the Gulf Of Mexico Air Quality Study, was conducted 

by other agencies during the summer of 1993 . As a part of this project, rawinsondes 

were launched at least twice daily from an offshore platform in the deep Gulf. This 

dataset was employed for the analysis of the marine atmospheric structure . It was 

3 
found that the average overwater mixing height was approximately 670 meters during 

daytime hours .

METHODOLOGY 
METHODOLOGY 

Two air quality and meteorological monitoring sites were established during 

the summer of 1993 within the Breton National Wildlife Refuge . The first was set up 

on the beach at Gosier Island, located at approximately 29°33 .69'N 89°03 .39'W. The 

second was installed on a semi-permanently moored vessel, the Chandeleur Islander, 

near Breton Island at approximate location 29°29 .34N 89° 10 .45 W. A third station 

was later added at the Pass-A-Loutre headquarters in the Delta Wildlife Refuge . The 

following sections describe each site in detail . 

Gosier Island 

Design and operation of the Gosier air quality station proved to be the most 

difficult of the three sites . At the request of the MMS, the station was deployed on 

the beach just beyond the surf zone . Immediately behind the site was a small pond 

bordered by a vegetated sand ridge . The entire area was a protected nesting habitat 

for various waterfowl. Due to the remote location, commercial power and facilities 

were not available . Therefore, a battery-powered system was designed to operate the 

air quality monitor and accessories . The components included a Thermo 

Environmental Model 43A SO, Analyzer and a Campbell Scientific CR10 datalogger . 

A ventilated wooden enclosure was built to house the system and placed upon a 

scaffold at a height of approximately 8 feet . The power inverter and the monitor 

itself drew a significant load on the battery array, hence continuous monitoring was 

not feasible . The CR10 was programmed to activate the analyzer each hour and allow 

it to run for five minutes, recording a sample each minute . At the end of the 

deployment, the sample interval was increased to half-hourly . 

The station was established on 7 July 1993 for testing, and actual monitoring 

began on 1 5 July . Although S02 concentration and temperature values were recorded 

throughout the field program, the data through August was suspect and not used in 

this study . By mid-August, it was noted that corrosion on the AC relay contacts had 

periodically prevented the SO, monitor from powering up, resulting in zero (or 

negative) values . By the end of August, the monitor's UV lamp had malfunctioned 

and the unit was pulled for repairs . A data gap is present from that point until 8 

September, when the station was re-deployed . 

A serious obstacle presented by these remote locations was that standard 

monitoring and calibration techniques were not possible . In this regard, a 

calibration system consisting of flowmeters in a gas proportioner, a zero air 

cylinder, and a certified S02 / Nitrogen calibration cylinder was assembled . 

Flowmeter calibration was performed at the Louisiana Department of Environmental 

Quality . The certified SO, cylinders were not available until the end of August, 

therefore no calibration was performed on either the Gosier or Breton station prior 

to that time . 

The Gosier S02 analyzer was immediately calibrated upon setup on 8 

September. It was then programmed to sample every 1/2 hour and set to run . On 17 

September the field measurements concluded. Since the batteries on site were too 

weak to allow calibration, the unit was returned to the CSI lab where a postcalibration was performed on 20 September. The precision data for the two 

calibrations are listed in Table 1 . 

7 
During the September monitoring period, the highest recorded concentration 

of SO, at Gosier Island was 10 .4 ppb on 1 1 September 1993 at 1 100 CDT.

Breton Island 

The Chandeleur Islander, a semi-permanently moored fishing houseboat 

adjacent to Breton Island, served as host to our second air quality site . Since AC 

power (produced by the boat's generators) was available here, this site was designed 

as a continuous backup for the more remote Gosier Island installation . The air 

quality system was again comprised of a Thermo Environmental Model 43A S02 

Analyzer and a Campbell Scientific CRI O datalogger . Wind speed and direction was 

provided by a Qualimetrics Stratavane Windbird mounted at approximately 9 m above 

the waterline . An Anderraa compass was also installed to determine the bow heading 

and thus the true wind direction . 

Data collection was begun on 1 5 July . However, the first routine service trip 

on 27 July found the SO, monitor's pump bearings failing and overheating . The unit 

was pulled, producing the only significant gap in the data record . A Monitor Labs 

SO, Analyzer was obtained on loan from the Louisiana Department of Environmental 

Quality, and measurements resumed on 3 August . Although uncalibrated, the unit ran 

throughout the month until replaced on 26 August with the repaired Model 43A. The 

first field calibration was performed at this time . Recorded S02 values from 4-8 

September were reported as zero (or negative) due to the monitor's flasher being 

ajar, cause unknown . After calibration on 8 September, monitoring continued until 

the site was removed on 17 September. Table 2 lists the precision calibration checks 

for the Breton site . 

After the initial calibration on 26 August, the highest hourly concentration of 

SO, was 22 .2 ppb on 1 September 1993 at 0800 CDT with a wind speed of 8 .5 mph 

from 45° . For the final week of intensive monitoring, the highest concentration was 

18 .8 ppb on I 1 September 1993 at 2000 CDT with a wind speed of 1 .9 mph and 

direction of 95° .

Pass-A-Loutre 

The final monitoring station was provided under subcontract to ESE, Inc. The 

equipment was set up at the Pass-A-Loutre headquarters complex located within the 

Delta Wildlife Refuge . System components included a Thermo Environmental Model 

43A S02 Analyzer, a Thermo Environmental Model 146 Calibrator, an Odessa Model 

3260 datalogger, Climatronics Weather System, Soltec Model 1243 Strip Chart, and 

calibration accessories . Hourly values of wind speed and direction, air temperature, 

and S02 concentration were recorded from 22 July through 15 September 1993 . 

Meteorological data was missing during a 5-day period in August ; however overall 

pollutant and meteorological data capture was 94 .6 percent. 

Table 3 presents the SOZ precision calculations for the sampling period . The 

precision data are reported as a 95 percent confidence interval bounded by two 

percentile values . The interpretation is that for any randomly selected value within 

the database represented, there is only 5 percent probability that its accuracy is 

outside of the boundaries defined as the upper and lower 95-percent confidence 

limits . 

The highest 1-hour SOZ concentration of 1 1 ppb was recorded twice during the 

study period . The first time occurred at 1300 hours on August 17th with wind 

direction of 34° and wind speed of 3 .5 mph. The second maximum occurred on 1 

September at 0900 hours with wind direction of 23° and wind speed of 2 .6 mph . It is 

interesting to note that the highest concentration at Breton Island occurred almost 

simultaneously to the latter Pass-A-Loutre maximum .

Site Comparison 

Special effort was made during the last week of the field deployment to ensure 

that the S02 monitors at all sites were calibrated and functional . Field calibrations 

were conducted on 8 September 1993 and again at the conclusion of the monitoring 

program . For comparative purposes, data from the period of 8-15 September 1993 

are shown in Figs . 2-5 . 

Good agreement is noted between the Breton Island and Pass-A-Loutre wind 

data . While some correlation amongst the temperature data is seen, the variations 

can be explained by the fact that the Pass-A-Loutre value represents the ambient air 

temperature while the other two are the temperatures within the datalogger 

enclosures . Finally, both Breton and Gosier show a rise in SO, concentration during 

1 1 September while Pass-A-Loutre detects little change . As described previously, 

the highest value was 18 .8 ppb at Breton Island on 1 1 September at 2000 CDT with 

wind direction of 95° and speed 1 .9 mph . Gosier also has peaks of 10 .4 and 9 .3 ppb 

on this day at 1 100 and 2300 CDT, respectively . Throughout the 1 1 th the winds were 

light and gradually turning from North to East .

RESULTS AND DISCUSSION 
RESULTS AND DISCUSSION 

The concentration of atmospheric pollutants is inversely proportional to the 

wind speed . Generally speaking, the wind speeds are lower in the summer than in 

other seasons . With this in mind, we were funded by the Minerals Management 

Service to measure the .SOZ concentration in the summer of 1993 in the Breton 

Wilderness area . Major results are summarized in Fig . 6 . Note that the highest S02 

concentration in the summer of 1993 are incorporated in the figure so that they can 

be compared to the National Ambient Air Quality Standards (NAAQS) . Since the 

maximum 24 hr NAAQS for S02 is 140 ppb for both primary and secondary standards, 

we use this value for our brief discussion here . In the summer of 1993 the averaged 

maximum 24 hr was 3 ppb, which is approximately 2% of the 140 ppb allowable once 

a year . Figure 6 also delineates the PSD increments of the SO, for 24 hr maximums, 

which is approximately 2 ppb . The Breton Wilderness area is also a Class I area, so 

the PSD values must be applied. Therefore, we have about 5 ppb for the 24 hr 

maximum, which is below 5% of the maximum 24 hr value of 140 ppb allowable once 

per year . 

In our area, atmospheric frontal systems become active in September . An 

example of the SO, measurements in the Fall is provided in Table 4 . It shows that 

after the passage of a weak cold front on September 1 1, 1993, when the wind blew 

from the land to the Gulf, the S02 concentration was at least twice as high as when the 

Bermuda High Pressure System resumed its normal influence, i .e ., when the wind 

blew from the Gulf toward land . Therefore, the SOZ concentration in our area may be 

due to sources from both land and the offshore region .

In the summer of 1993, rawinsondes were launched over the deep Gulf of 

Mexico from the Chevron platform GB 236A located at approximately 27 .8°N 93 .10W . 

Launches were made at least twice daily at 0700 and 1900 CDT, and occasionally at 

1300 CDT . This dataset was analyzed in order to determine the variation of the 

average marine atmospheric mixing height . Values of 8 (potential temperature °C) 

and q (mixing ratio in gm /kg) were plotted through the first 2000 m for each profile 

as provided in Fig. 7 . Mixing height was defined here as the height at which dq / dz 

and d8 / dz became » 0 . 53 clearly-defined cases were found . The variation of the 

17 
average atmospheric mixing height is shown in Fig. 8 . Between 7 :00 A .M . and 7 :00 

P .M . over the deep Gulf of Mexico, the average height was approximately 670 m 

above the mean sea level with a standard deviation of about 100 m . Since air and sea 

surface temperatures are nearly homogeneous in the summer months, the mixing 

height statistics from GB 236A can be used to approximate the conditions over the 

Breton and Delta Refuges . 

In summary, on the basis of our S02 measurements in the summer of 1993 in the 

Breton and Delta Wildlife Refuges, the S02 concentration in these Class I and Class 

II areas, respectively, was only 2% of the National maximum allowable once per year . 

However, we also found that when the wind blew from land to our Class I area 

offshore the S02 concentration was more than twice as compared to the 

meteorological condition when the wind blew from the Gulf toward the land .

RECOMMENDATIONS 
RECOMMENDATIONS 

It is recommended that detailed (hourly) measurements of the SO, concentration for an entire one-year period be made in order to separate the contributions from 

the offshore region vs . land sources . In addition, an SO, transport trajectory 

climatology, including more upper-air soundings to determine overwater spatial and 

temporal variations of the atmospheric mixing layer, should be thoroughly 

investigated for the Gulf Coast region .
