        Title: Weeks Bay Water Sampling and Hydrographic Profiles 1990-2000
        Geospatial_Data_Presentation_Form: database
    Description:
      Abstract: This dataset contains ten years of physical, chemical, and biological data collected during shipboard surveys in Weeks Bay, Alabama, between June 1990 and May 2000. Surveys consisted of up to 19 stations throughout Weeks Bay and just beyond its mouth in Bon Secour Bay. Hydrographic profiles and water samples were collected at each station.
      Purpose: To examine the effects of river discharge, suspended sediment dynamics, and nutrient inputs on phytoplankton and higher trophic level production in the Weeks Bay ecosystem.
      Supplemental_Information: Data in this dataset are compiled from two separate studies, one from 1990-1992, the other from 1996-2000.

      Process_Step:
        Process_Description: Field Sampling - Hydrographic: A Hydrolab Surveyor II was used to collect hydrographic profiles of salinity, temperature, dissolved oxygen, and pH.  These profiles were taken at discrete sampling depths and stored to memory until being downloaded upon return to the laboratory.   In addition to the Hydrolab profiles, the underwater light regime was quantified using a LiCor Quantum Irradiance Meter fitted with a 3pi spherical deck and underwater sensors or, on a few occasions, a 20 cm secchi disk.  LiCor profiles were carried out at 10 cm increments through the photic zone. The diffuse attenuation coefficient for PAR (k; m-1) was calculated for each station via regression of ln irradiance vs. depth for the entire subsurface profile after correction of irradiance for instantaneous variations in surface irradiance.  Secchi measurements were estimated to the nearest 5 cm.  Field Sampling - Discrete Water: 5-liter PVC Niskin bottles were deployed to collect water samples at the surface and one meter above the bottom at all stations.  Upon sampling, 1 liter of water was collected into an acid washed, deionized water and sample rinsed 1-liter HDPE bottle.  Samples were maintained in the dark on ice until return to the laboratory.  Also, 1 liter of water for phytoplankton production experiments was collected in polycarbonate bottles and held at ambient temperature in the dark until processing.  In addition, samples for dissolved inorganic carbon (DIC) were collected in glass scintillation vials, capped without air contamination, and returned to the laboratory for immediate analysis.  Finally, 20 ml samples for phytoplankton taxonomy were collected and fixed with 2 drops of Lugol's Solution.  Upon completion of water collection, temperature and salinity were measured in all discrete samples using an Orion temperature/conductivity probe with a resolution of 0.1 degrees C and 0.1 ppt.  These latter discrete measurements are reported in this data set.

      Process_Step:
        Process_Description: Laboratory Methods - Dissolved Matter: In the laboratory, samples were split into dissolved and particulate fractions using Whatman GF/C glass fiber filters that had been muffled (450 degrees C for 2 hours) to remove organic contamination.  These filters have a nominal pore size of 1.2 um.  Dissolved Inorganic Carbon (DIC): DIC was determined from samples for analysis using a Shimadzu TOC-5000 fitted with a non-dispersive IR detector.  This instrument has a precision of +/-10 uM at a concentration of 1500 uM.  Dissolved Inorganic Nutrients: Dissolved nutrients were measured in sample water filtered through a Whatman GF/C filter.  Phosphate, ammonium, nitrate, nitrite, and silicate were analyzed by standard colorimetric methods (Strickland and Parsons, 1972) adapted for use on an Alpkem RFA/2 Autoanalyzer.  Detection limits are 0.01 uM (NO3, NO2, PO4), 0.02 uM (NH4), and 0.05 uM (SiO2).  Standard error for all measurements ranges from 2-3%.  Dissolved Organic Carbon (DOC): DOC was determined in filtered (GF/C) sample water which was sealed in muffled glass scintillation vials and frozen until analysis using a Shimadzu TOC-5000.  For analysis, the sample was acidified and sparged with zero-grade air to remove inorganic carbon and then analyzed to obtain the total organic carbon concentration.  This method has a detection limit of 10uM and standard error of +/-5% at 300 uM.  Dissolved Organic Nitrogen (DON): Total dissolved nitrogen (TDN) was analyzed on GF/C filtered samples following the persulfate oxidation method of D'Elia (1977).  Inorganic N (NO3- + NO2-, NH4+) was subtracted from TDN to give DON.  This method has a detection limit of 0.6 uM +/-1%.    Dissolved Organic Phosphorus (DOP): Total dissolved phosphate (TDP) was determined by the high temperature combustion method of Solorozano and Sharp (1980). Inorganic PO4 was subtracted from TDP to give DOP.  This method has a standard error of +/-5%.

      Process_Step:
        Process_Description: Laboratory Methods - Particulate Matter: In the laboratory, samples were split into dissolved and particulate fractions using Whatman GF/C glass fiber filters that had been muffled (450 degrees C for 2 hours) to remove organic contamination.  These filters have a nominal pore size of 1.2 um.  Suspended Sediments: Total suspended sediments (inorganic sediment plus living and dead organic matter) was determined by passing a known volume of water through a pre-washed and pre-weighed 47 mm GF/C filter.  After filtration, each filter was rinsed with deionized water to remove salts, dried at 50 degrees C, cooled and re-weighed following the methods of Strickland and Parsons (1972).  This method has a detection limit of 0.1 mg l-1 with a standard error of +/-5%.    Particulate Carbon and Nitrogen (PC/PN): PC and PN were measured on particulate matter collected on a 25mm GF/C filter via high temperature combustion (Sharp, 1974) using a Carlo-Erba NA 1500 Carbon-Nitrogen-Sulfur (CNS) analyzer fitted with a thermal conductivity detector.  This method has a detection limit of 1.0 uM with a standard error of +/-5%.  Particulate Phosphorous (PP): PP was determined by conversion of particulate phosphorous to dissolved inorganic phosphorous by high temperature combustion according to the method of Solorzano and Sharp (1980).  This method has a detection limit of 1.0 uM with a standard error of +/-1%.

        Process_Description: Laboratory Methods - Phytoplankton Biomass and Production: In the laboratory, samples were split into dissolved and particulate fractions using Whatman GF/C glass fiber filters that had been muffled (450 degrees C for 2 hours) to remove organic contamination.  These filters have a nominal pore size of 1.2 um.  Chlorophyll-a: Chlorophyll a was extracted on Whatman GF/C filters for 24 hours in cold 90% acetone and measured by fluorometry (Strickland and Parsons, 1972) to account for the presence of phaeopigments (Lorenzen 1967).  The Turner Designs Model 10 fluorometer was calibrated with spectrophotometric measurements of pure chlorophyll a (Sigma Chemical).  This method has a detection limit of 0.01 ug l-1 with a standard error of +/-5%.   Phytoplankton Production: Phytoplankton production was measured by the incorporation of NaH14CO3 into particulate matter over 24-hour incubations at six light intensities (100, 57, 26, 9, 5, 1% ambient) using neutral density screen bags in a flow-through deck incubator (Pennock and Sharp, 1986).  Incubations were terminated by filtering the particulate matter onto Whatman GF/C filters and rinsing with filtered ambient water.  Filters were placed immediately into scintillation vials filled with 5 ml of Beckman Ready-Safe scintillation fluor and counted on a Packard Tri-Carb liquid scintillation counter.  Maximum production per unit volume (mg C l-1 d-1) was determined using the maximum rate obtained from the 6 point light series.  Areal production was determined by integrating the values obtained at each of the light levels by the light profile described by the diffuse attenuation coefficient, following the methods of Pennock and Sharp (1986).
