This data package contains MOCNESS (Multiple Opening/Closing Net Environmental Sensing System) profile data and other ichthyoplankton and decapod specimen identification data collected during Natural Resource Damage Assessment (NRDA) Plankton Survey Nick Skansi PC4 (NSPC4) in the Gulf of Mexico from 2010-10-16 to 2010-10-24. This survey was part of a series of NS NRDA cruises conducted in 2010 and 2011 to evaluate the distribution and densities of ichthyoplankton and other zooplankton in northern Gulf of Mexico waters potentially affected by the Deepwater Horizon Oil Spill (DWHOS). The data package includes the original profile data representing environmental samples (e.g., temperature, salinity, pressure) for individual MOCNESS tows as well as combined and summary data (all tows) for the full cruise. Dataset also includes sampling event data (e.g., time, latitude, longitude, depth, volume filtered) and specimen data (e.g., taxonomic identification, length, number of individuals).

This dataset reports plankton species abundance from 14 sites off the Florida Panhandle Bight at the head of DeSoto Canyon, Gulf of Mexico aboard the R/V Bellows cruise BE-1317 from 2013-04-06 to 2013-04-08. Plankton samples were collected using a net with a mesh size of 25 micrometer and 0.5m diameter. This dataset reports the location, date, time, and length of tow for each sample. Plankton species were categorized as Ceratium spp., Dinophysis spp., other dinoflagellates, Chaetoceros/Bacteriastrum spp., Rhizosolenia/Guinardia spp, Eucampia/Hemiaulus spp., other chain-forming diatoms, Thalassionematales spp., Nitzschioid diatoms, other diatoms, Cyanobacteria (Trichodesmium spp.), and zooplankton. Abundances were recorded as individual counts as well as percentages of the total sample. Quantitative phytoplankton profiles were taken specifically at 5 sites (P1, P3, P5, P7, P9). For this, one-liter samples were collected from the surface and at different depths using Niskin bottles. Samples were filtered onto a 0.45 micrometer nitrocellulose filter and air-dried. A portion of each filter was mounted on an aluminum stub, sputter-coated, and examined with a JEOL JSM-6480 LV scanning electron microscope. Diatoms, coccolithophores, and armored dinoflagellates were identified to the lowest possible taxonomic category. The number of cells of each taxon in a field of view at a magnification of 1000x was recorded, with up to 700 fields-of-view examined, depending on the density of phytoplankton in the sample. The dataset includes the depth, the volume filtered, the number of cells of each taxon counted, and the calculated abundance of each taxon in cells per liter. Micrographs taken during the analysis are included.

This dataset reports plankton species abundance from 5 sites off the Florida Panhandle at the head of DeSoto Canyon, Gulf of Mexico aboard the R/V Bellows cruise BE-1415 on 2014-05-31. The R/V Bellows cruise BE-1415 extended from 2014-05-29 to 2014-06-01. Quantitative phytoplankton profiles were collected at 5 sites (P1, P3, P5, P7, P9) along the Pensacola transect (Longitude -87.25 degrees N). For this, one-liter samples were collected from the surface and at different depths using Niskin bottles. Samples were filtered onto a 0.45-micrometer nitrocellulose filter and air-dried. A portion of each filter was mounted on an aluminum stub, sputter-coated, and examined with a JEOL JSM-6480 LV scanning electron microscope. Diatoms, coccolithophores, and armored dinoflagellates were identified to the lowest possible taxonomic category.
