      Abstract: 
          This dataset contains measurements of mesozooplankton gut phaeopigments and associated metadata collected from 
          13 sampling locations during R/V Point Sur cruise PTS03 from 2016-07-24 to 2016-07-30 in the Mississippi 
          Bight, Gulf of Mexico. Mesozooplankton samples were taken during the spring of 2015 using a mininess 
          (BIONESS) tow system. Samples were taken from three nets, corresponding to three depth intervals (e.g., 
          bottom, midwater, surface). Nets had 202-micrometer mesh size, but in some cases, samples were taken from 
          nets with 0.333-micrometer mesh due to system issues. Samples were transferred into a bucket immediately 
          after retrieval and carbonated water was added to the sample to stop or avoid further 'net feeding' or 
          regurgitation from individual zooplankton. Typically, each net sample was split into two aliquots using a 
          Folsom Splitter aboard the ship. The 1/2 aliquot separated from the original sample was then split further 
          into two subsamples: one was used to measure mesozooplankton gut fluorescence and the other was processed 
          for dry weight (reported separately). When samples were too thick, the initial sample was split into smaller 
          aliquots (clearly indicated in the dataset). The corresponding aliquot was then size fractionated into five 
          size bins using sieves with meshes measuring: 0.212, 0.5, 1, 2, and 4.75 mm. Filtered seawater was used 
          during sample split and size fractionation. After fractionation, each sample was poured onto a GF filter 
          (2.5 mm diameter) using a filtering system aboard the ship, rinsed with DI water, wrapped in aluminum foil 
          and quick-frozen immediately after filtering by depositing the sample into liquid nitrogen. Before 
          filtering, each sample was kept in the dark in an ice bath. Samples were processed following Strickland and 
          Parsons (1968) spectrophotometric determination of phaeopigments protocol. These data will be used in 
          combination with other mesozooplankton net data to study zooplankton processes in the river-dominated 
          northern Gulf of Mexico. Data is reported in units of micrograms of phaeopigments per liter. Related 
          mesozooplankton size-fractionated dry weight data and BIONESS profile data are available under GRIIDC UDIs 
          R4.x260.000:0028 and R4.x260.000:0003 respectively. The gut fluorescence data come from the same net 
          analyzed for dry weight, and both gut fluorescence and dry weight data come from the net tows, BIONESS 
          profile datasets, which contains all the detailed information about the station, net start/end coordinates, 
          and sampling information.
      Purpose: 
          These data will be used in combination with other mesozooplankton net data to study zooplankton grazing rates 
          in the river-dominated northern Gulf of Mexico.

          net tow deployment), Net_Number (number of the BIONESS net where the sample was obtained), Net_Mesh_um (mesh 
          size, micrometers), Depth_Open_m (depth where the net started sampling, m), Depth_Close_m (depth where the 
          net stopped sampling, m), Swept_Volume_m3 (amount of water sampled by the net, m^3), 
          Mean_Temperature_Celsius (mean temperature measured by the environmental sensor system during the interval 
          the net was collecting samples, degrees C), Mean_Salinity_PSU (mean salinity measured by the environmental 
          sensor system during the interval the net was collecting samples, PSU), GF_Number (unique number of the 
          aliquot obtained from the net), Sieve_Size_mm (size of the sieve's mesh in millimeters where the subsample 
          was obtained for this analysis), Net_Split_Factor (fraction of the original sample taken from the net), 
          Filter_Section_Factor (fraction of the GF filter used for pigment extraction and laboratory analysis),

          dominant organisms found in filter; notes of non-grazing organisms removed prior to pigment extraction)|GF 
          filters were transferred from liquid nitrogen to -80 freezers and kept there until laboratory analyses. Gut 
          pigments were measured using the Strickland and Parsons (1968) spectrophotometric determination of 
          phaeopigments protocol. GF filters were processed in the following manner: for subsamples coming from sieve 
          sizes 4.75 & 2 mm the whole filter was used for pigment extraction; for subsamples from sieve size 1 mm, 1/4 
          of the filter was processed; and 1/8 of the filter was used for filters with samples from sieve sizes 0.5 
          and 0.212 mm. Pigment extraction was done in 90% acetone as per standard pigment analyses protocols and 
          using the acidification method (HCl). All laboratory analyses were conducted in dark conditions as much as 
          possible to avoid pigment photodegradation. Pigment measurements were carried out on an SpectraMax M2 
          (Molecular Devices) spectrophotometer using a cuvette of 1 cm path length.
          
          The nets were fished for about 6 minutes each. Volume swept and depth bin intervals were targeted to three 
          depth bins: deep, mid-water column, and near the surface. For these data, samples from 3 out of the 9 nets 
          used on the BIONESS dataset were used. The start and end coordinates and time for each of these 3 nets are 
          very close to each other that end towing information are not provided in this dataset. However, the full 
          station metadata, net data, and detailed environmental data for each net can be found in the BIONESS dataset 
          under GRIIDC UDI R4.x260.000:0003.||||Briseño-Avena, Christian, Alison L. Deary, Robert K. Cowen, Frank J.
