Security_Information: Security_Classification_System: None Security_Classification: Unclassified Security_Handling_Description: None Native_Data_Set_Environment: Windows 2000, MSAccess 2000 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: H01Hydrolab: The Hydrolab Surveyor 3 Conductivity, pH and Oxygen sensors were serviced and calibrated before deployment and maintained in accordance with Hydrolab (http://www.hydrolab.com/) recommended procedures. The Sonde and Logger are returned to the factory at least annually for inspection and service. There were sporadic problems with the Hydrolab conductivity sensor fluctuations in January, April, May and June. Small adjustments based on correlations with Portasal and SeaBird values were made to selected Hydrolab salinity data. Salinity data considered unreliable were deleted. Shipboard Winkler titrations during the July shelfwide cruise were used to develop a regression against Hydrolab data in case it was necessary to correct the data. Hydrolab oxygen data were corrected using an equation based on the results of the regression. H01Nutrients: January through October nutrient analyses were conducted using a Technicon (http://www.techniconinstruments.com/) autoanalyzer. November and December analyses were conducted using a (http://www.lachatinstruments.com) QuikChem 8000 FIA+. Tom Oswald performed the analyses under the supervision of R. E. Turner. H01Pigments: The Turner Designs model 10 AU fluorometer was calibrated for chlorophyll a against a chemical supply house chlorophyll a standard measured on a spectrophotometer. Each time the fluorometer was moved, it was tested with a Turner 10-AU solid standard. During cruises, the fluorometer was blanked and calibrated daily in accordance with Turner Designs recommended procedures. Pigment measurements were supervised by Ben Cole or Nancy Rabalais and quality controlled by Nancy Rabalais. H01PortaSal: Salinity samples were analyzed in the lab by Guildline Instruments PortaSal, using Guildline methods (http://www.guildline.ca/). Salinity analyses were conducted by Jim Lee under the supervision of R. E. Turner. H01Refract: The refractometer was checked with distilled water before each cruise and re-zeroed when necessary. H01SeaBird: Sea-Bird SBE 13-01 dissolved oxygen sensors, the Paroscientific Digiquartz(r) pressure sensor, the SBE 3-01/F temperature sensors, SBE 5-01 pumps, and the SBE 4-01/0 Conductivity sensors were factory tested and calibrated at Sea-Bird (http://www.seabird.com/) recommended intervals and maintained and serviced by RV Pelican Electronic Technical support staff in accordance with Sea-Bird procedures. The Sea Tech 500m Fluorometer and Sea Tech 5.0 cm Transmissometer were factory tested and calibrated at Sea Tech recommended intervals and maintained and serviced by RV Pelican Electronic Technical support staff in accordance with Sea Tech procedures. Note: WET Labs acquired SEA Tech June 1, 1998, (http://www.wetlabs.com/). The Wet Labs C Star 10 cm path transmissometer was maintained by RV Pelican Electronic Technical support staff in accordance with Wet Labs recommendations. At the beginning of the each cruise, oxygen sensors were calibrated using the procedures described in SeaBird APPLICATION NOTE NO. 13-1, Rev. D. The Winkler Titration (OXFITW) oxygen value was determined chemically from replicate samples processed using a Mettler DL21 Titrator (http://www.mt.com/). On the cruises in January, March, April, October, November and December the water column at most stations was well mixed. Shipboard Winkler titrations for regressions were not considered useful (not enough data range to develop a strong regression) and were not made. Shipboard Winkler titrations during the July shelfwide cruise were used to develop a regression against SeaBird data in case it was necessary to correct the data. The Seabird data agreed with the Winkler values and no correction was necessary. Winkler titrations were conducted under the supervision of Nancy Rabalais. Data reductions from the SeaBird were generated by Ben Cole and quality controlled by Nancy Rabalais. H01SPM: Suspended sediment concentrations were supervised by Ben Cole or Nancy Rabalais and quality controlled by Nancy Rabalais. H01Stn: January, March, April, July, October, November and December monthly survey times and locations of operations were logged from RV Pelican's Multiple Instrument Data Acquisition System (MIDAS) which was maintained by the ship's electronic staff. Navigational data were acquired from a Starlink (http://www.starlinkdgps.com/) differential GPS or a Trimble (http://www.trimble.com/)GPS with a Micronet Receiver Station with sub 5-meter accuracy. Station depths were logged from the ship's Odom Echotrac II (http://www.odomhydrographic.com/) fathometer. February, May, June, August and September monthly survey station times, locations and depths were logged from RV Acadiana's Garmin GPSMAP 168 Sounder (http://www.garmin.com/). In addition to the monthly surveys, Hydrolab casts were made on a few dates from a small boat. See Horizontal_Positional_Accuracy_Report for details. Secchi disk depths were measured by hand using standard protocol. N. Rabalais performed an additional procedure in quality-control/quality-assurance by evaluating relationships between the data in H01Hydrolab, H01Nutrients, H01Pigments, H01PortaSal, H01Refract, H01SeaBird, H01SPM and H01Stn. Logical_Consistency_Report: Hydrolab oxygen sensor maximized at 0.2m depth at station A'2, 20010720. The values reported for Dissolved Oxygen: 99.99 and Percent Oxygen Saturation: 999.9 indicate oxygen levels were equal to or higher than 20.0 mg/L and 200 percent saturation. The fluorometer in the SeaBird CTD package had maximum value of 15. Fluorometer values of 15 were observed at twenty-seven stations. See FlS entity Detailed_Description for details. The maximum fathometer depth (Fath) reported in table H01Stn is 52.4 meters. The maximum depth pressure sensor depth (DepS) reported in table H01Hydrolab is 52.6 meters. Beginning with the October survey, the transmissometer used with the SeaBird CTD was changed from a SeaTech transmissometer to a Wet Labs transmissometer. Completeness_Report: When data quality criteria were not met, SPM data were not included. Conductivity, salinity and density values at one or more depths were deleted from thirty-seven stations because the data were not considered reliable. Nutrients analytical instruments and methods changed in November 2001. Beginning November 2001, nitrites and nitrates were not reported separately. The SeaBird transmissometer was not functional at station C1 on the January survey. The transmissometer was not functional at any of stations surveyed in November. The electronic data file for station C5 on the date 20010721 was not archived. The results reported in the table H01SeaBird came from a SeaBird MRK file created when Niskin bottles were fired. The parameter OxPS (percent oxygen saturation) was not recorded in the MRK file. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: January, March, April, July, October, November and December cruise station positions were logged from RV Pelican's differential GPS at the beginning of sampling operations. GPS manufacturer's accuracy claim is 1-5 meters 95% of the time. Wind, currents and tidal forces may have moved the ship from the beginning position. Station positions acquired during February, May, June, August and September on RV Acadiana were logged from the ship's Garmin Garmin GPSMAP 168 Sounder with with Garmin GBR 21 DGPS. The manufacturer describes the accuracy to be between 1 - 5 meters 95% of the time. Wind, currents and tidal forces may have moved the ship from the beginning position. Hydrocasts were made from Whiskey Pass, a small boat, on the following dates: 20010618, 20010706, 20010823, 20010906, 20010906, 20010924, 20010924 and 20011113. The boat tied up to oilfield platforms at stations C6B or CST52. Lineage: Methodology: Methodology_Type: Field Hydrolab monthly C and F transect surveys Methodology_Description: Deployment: The Hydrolab CTD was attached by chain to a lead weight. The weight was lowered to the bottom by hydrowire. With the weight on the bottom, the Hydrolab sonde was positioned just above the bottom. When the oxygen sensor stabilized, a data record of all the sensor values was stored electronically. The sonde was raised in approximately 1.0-meter increments, after D.O. sensor stabilization, data records were stored. When the Hydrolab reached a depth of two to three meters from the surface, The sonde was raised, and records stored, in approximately 0.5-meter increments until finally a record was stored with the sonde submerged but as close as possible to the surface. Methodology: Methodology_Type: Field Hydrolab July shelfwide survey Methodology_Description: Deployment: Due to limitations of time, mid-water depths were generally not sampled with the Hydrolab CTD during the shelfwide cruise. The Hydrolab CTD was attached by chain to a lead weight. The weight was lowered to the bottom by hydrowire. With the weight on the bottom, the Hydrolab sonde was positioned just above the bottom. When the oxygen sensor stabilized, a data record of all the sensor values was stored electronically. The sonde was raised in approximately 0.5-meter increments, after D.O. sensor stabilization, data records were stored. After storing data for the few meters closest to the bottom, the sonde was raised to two to three meters from the surface and a data record was saved. The sonde was raised, and records stored, in approximately 0.5-meter increments until finally a record was stored with the sonde submerged but as close as possible to the surface. Methodology: Methodology_Type: Field Nutrient January through October Methodology_Description: Care was taken that the collector's hands were clean and avoided touching the sample water. Gloves were worn when three replicate sample vials and caps were triple rinsed with sample before vial filling and closing. Samples were not filtered. The sample vials were frozen for later analysis in the laboratory. Methodology: Methodology_Type: Field Nutrient November through December Methodology_Description: Care was taken that the collector's hands were clean and avoided touching the sample water. Gloves were worn when two replicate sample vials and caps were triple rinsed with sample before vial filling and closing. Samples were not filtered. The sample vials were frozen for later analysis in the laboratory. Methodology: Methodology_Type: Field Pigment Methodology_Description: Water for chlorophyll analysis (30 - 100 ml) was filtered on board ship through GF/F (0.7 micron) filters, which were then fixed in 5 ml of DMSO/90% acetone (40/60) solution, allowed to extract for at least two hours in the dark, then measured pre- and post-acidification on a Turner Model 10 AU fluorometer. Methodology: Methodology_Type: Field PortaSal Methodology_Description: Water was collected in an acid-washed, triple-rinsed 500ml Nalgene jar from a twice-rinsed bucket of surface water. The jar lid was secured tightly to minimize evaporation. Methodology: Methodology_Type: Field SeaBird Methodology_Description: The SeaBird CTD number of scans to average in the deck unit was set to one. At the beginning of each hydrocast the entire CTD/Rosette package was soaked while submerged 0.5m to 1.0m below the surface until pump flow and oxygen values observed via the Sea-Bird deck unit indicated the system was operating correctly. In order to minimize the effect of delays in oxygen sensor response time caused by temperature, sensor condition and plumbing configuration, the CTD package was lowered as close to dead slow as possible. The sensor packages were located below the Niskin bottles and rosette. At stations where the watch chief deemed the structure of the oxygen profile contained features useful in post-processing the oxygen data (AlignCTD), the CTD package was raised at the same speed it was lowered. At all other stations, the upcast was rapid in order to save time. Methodology: Methodology_Type: Field SPM Methodology_Description: Water (approximately 300 to 1000 ml) collected for suspended sediment samples was filtered on board ship through (pre-combusted, pre-weighed) GF/F filters and rinsed with distilled water. The filters were placed in Petri dishes and frozen for later analysis. Methodology: Methodology_Type: Field Station Locations Methodology_Description: C transect lies South and East of Terrebonne Bay. Nine cross-shelf stations on C transect were sampled monthly (except January and December). Additional water-column hydrology measurements were made at station C6B when other research missions provided opportunities at that location. Seven stations on transect F, South of the Atchafalya River were sampled in January, March, May, September November and December. During the July shelfwide cruise, stations were occupied along 15 generally North-South transects across the Louisiana coastal shelf. Station depths ranged from 3.25 to 52.4 meters. The objective was to delimit and describe the area of midsummer bottom dissolved oxygen less than 2 (mg/L). Northern end stations of transects were chosen based on the survey vessel's minimum depth limits for each longitude. The northern extent of hypoxia was not reached on transects A', A, B, E, F, H and I. The limit of hypoxia on the southern end of transect P was not reached. The limit of hypoxia was not reached at three of 5 stations on the western end of the survey. The limit of hypoxia was not reached at three of five stations on the eastern end of the survey. Methodology: Methodology_Type: Field water samples Methodology_Description: Water for chlorophyll, nutrient, salinity and suspended sediment analyses was collected from the surface by twice-rinsed bucket, from mid-water in 5-l Niskin bottles on the SeaBird CTD/rosette system or a messenger triggered 5-l Niskin on the Hydrolab hydrowire. Bottom samples were collected in a 5-l bottom tripping Niskin deployed on the Hydrolab hydrowire. During the shelfwide cruise because of funding and time constraints bottom samples at station H6, stations 1, 2, 5, 6 and 7 on transect I and all stations on transects J, K, M and P were collected using Niskin bottles on the SeaBird rosette. Depth values of "0" indicate a bucket sample collected from the surface of the water. Generally, deepest depths of water samples were from the bottom-tripping Niskin and correspond to the deepest depth recorded from the Hydrolab. As noted in the preceding paragraph, bottom water sample-depths on transects J, K, M and P and station H6 and five station on transect I were the depths of the pressure sensor reading for 5-l Niskin bottles on the SeaBird rosette. The SeaBird pressure sensor was located approximately 0.75 meters below the mid-point of the 5-l Niskin. Samples at 6.5m and 14.0m at Station C6B were collected using Niskin bottles on the SeaBird rosette in January, March, April, July, October, November and December. 6.5m and 14m at Station C6B were collected using a messenger fired Niskin on the Hydrolab hydrowire in the months February, May, June, August and September. Methodology: Methodology_Type: Lab Nutrient January through October. Methodology_Description: Nitrogen and phosphorus were analyzed according to methods described in EPA publication EPA 600/4-79-020 (1979), method 350.1 for ammonia-N, method 353.2 for nitrate/nitrite-N, and method 365.1 for phosphate-P. Silicate was analyzed according to Technicon Industrial method 186-72 W/B (1977). Methodology: Methodology_Type: Lab Nutrient November and December Methodology_Description: Ammonia samples were analyzed according to Lachat Instrument's QickChem method 31-107-06-1-B. Phosphates are determined by Lachat Instrument's QuickChem Method 31-115-01-1-H. Silicates were measured using Lachat Instrument's Method 31-114-27-1-C. TKN was determined using Lachat Instrument's QuickChem Method 10-107-06-2-H. Nitrate and Nitrite were determined using Lachat Instrument's Method 31-107-04-1-C. Methodology: Methodology_Type: Lab SPM Methodology_Description: Suspended sediment filters were dried overnight at 60°C and weighed. The filters were then combusted at 400°C for 12 hours and weighed. The weights of the total suspended, organic and inorganic materials were derived. Methodology: Methodology_Type: Lab SeaBird Methodology_Description: Sea-Bird CTD data were acquired using Seasoft version 4.236. January through April data were post-processed with Seasoft version 4.247. July through December data were post-processed with Seasoft version 4.249. All scans were processed without averaging or interpolation with a bin size of one scan. In order to improve alignment between oxygen sensor values and other CTD sensor values, the Seasoft module ALIGNCTD was used, when possible, to determine which advance best compensated for the delay in oxygen sensor response time. When SeaBird data were processed, dissolved oxygen was advanced relative to temperature and conductivity values as follows: February 3 seconds, March 3.125 seconds, April 3.5 seconds, July 2.9 seconds, October 3 seconds, November 3.3 seconds, December 3.375 seconds. Data values reported are from downcasts. Downcast scans selected for each CTD station were chosen to illustrate: 1) data values as near to the surface as possible, 2) data values at whole meter increments, and 3) data values as close to the bottom as the CTD was lowered. In certain cases where data values of a parameter changed significantly between whole meter increments, 0.1- or 0.2-meter scans were selected. Process_Step: Process_Description: Unknown.
