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.

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),
Gut_Phaeopigments_ug_per_L (micrograms of mesozooplankton gut phaeopigments per liter), Notes (notes of

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.

MCORR= middle corridor, ECORR= eastern corridor, WCORR= western corridor, ARRAY= mixing mooring array), Date_UTC (dd/mmm/yy, UTC), Time_UTC (time when net was deployed, HH:MM, UTC), Latitude_Decimal (location of net deployment, decimal degrees North), Longitude_Decimal (location of net deployment, decimal degrees West), Tow_Number (unique number ID of the 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), Gut_Phaeopigments_ug_per_L (micrograms of mesozooplankton gut phaeopigments per liter), Notes (notes of 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.
