<div><p>The Bongo Plankton Net was deployed according to the "NOAA SEAMAP Field Operations Manual for collection of data, Chapter V., National Marine Fisheries Service and Gulf States Marine Fisheries Commission, October 2001, Revision No.4."</p>
<p>Target Fishing Depth as much of the water column as possible stopping 2-4m above the bottom at bottom depths <200m, and upper 200m at bottom depths >200m; ship speed 1.5-2.0 knots; target wire angle of 45°; winch speeds during pay out and retrieving according to Chapter V., Table A.</p>
<p>Nets were rinsed and processed on board and samples were preserved in 200 proof Ethanol (ETOH) according to NOAA SEAMAP Operations Manual upon retrieval of nets. After 24 hours, ETOH was exchanged with fresh ETOH. Plankton samples were stored in 1000ml plastic jars until processing in the Geist Early Life History Research Laboratory at Texas A&M University Corpus Christi during 2017 and 2020. Total Zooplankton Displacement Volume was determined using a calibrated 1000ml measuring cylinder by subtracting the volume of ethanol without sample from the volume of ethanol with sample. The plankton sample was separated from ethanol using a concentrator sieve with a mesh size less than the net mesh size. Then the plankton sample was resuspended in Ethanol. Larval fish were picked under dissecting microscopes using feather steel tweezers. Every sample was looked through twice for quality check purposes.</p></div>
Ichthyoplankton density and Plankton Displacement Volume data collected during the NSF RAPID Plankton Cruises using NOAA SEAMAP Bongo Plankton Nets
Ichthyoplankton Density - Bongo
<div><p><strong>Data Processing: </strong><br />
Filtered Volume was calculated according to the manufacturer manual of the flowmeter (General Oceanics):</p>
<p>Filtered Volume = distance towed * net opening area,</p>
<p>with distance towed calculated as:</p>
<p>Flowmeter Count Difference * Flowmeter Constant / 999999.</p>
<p>Total Plankton Displacement Volume and Total Larval Fish Density were standardized per 100m³ filtered water volume and per area as under 10m² water column using the same formula as NOAA SEAMAP Pascagoula Office (POC G. Zapfe).</p>
<p><strong>BCO-DMO Processing:</strong><br />
- concatenated separate files into one dataset;<br />
- converted date format to YYYY-MM-DD;<br />
- removed commas from the FM_CO field;<br />
- added ISO date-time fields;<br />
- added Cruise_ID numbers.</p></div>

Ichthyoplankton density and plankton displacement volume data collected using NOAA SEAMAP Bongo Plankton Nets on the NSF RAPID Plankton Cruises in the Northwestern Gulf of Mexico in 2017-2018
This dataset includes ichthyoplankton density and plankton displacement volume data collected using NOAA SEAMAP Bongo Plankton Nets during three NSF RAPID Plankton cruises and one NOAA Plankton cruise. RAPID Plankton Cruise 1 took place on R/V Point Sur, cruise number PS1813, from October 28-November 3, 2017. RAPID Plankton Cruise 2 took place on R/V Pelican, cruise number PE18-18, from January 6- 12, 2018. RAPID Plankton Cruise 3 took place on R/V Pelican, cruise number PE18-21, from March 19- 23, 2018. The NOAA Plankton cruise took place on R/V Gordon Gunter, cruise number GU17-04, from September 04-30, 2017.
