Plankton samples were collected using a net with mesh size of 25 micrometer and 0.5m diameter. Plankton abundance data reports the location, date, time, and length of tow for each sample. Plankton species are categorized as Ceratium spp., Dinophysis spp., other dinoflagellates, Chaetoceros spp., Rhizosolenia/Guinardia, Eucampia/Hemiaulus, other chain-forming diatoms, Thalassionema spp., Nitzschioid diatoms, other diatoms, Cyanobacteria (Trichodesmium spp.), and Zooplankton. Abundances were recorded as individual counts as well as percentages of total sample. Diatoms and dinoflagellates were counted as cells, cyanobacteria as colonies/filaments, zooplankton as individuals. Quantitative phytoplankton profiles were taken specifically at 5 sites (P1, P3, P5, P7, D1) along the Pensacola transect. 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. The purpose of this cruise was to evaluate the biological diversity and trophic interactions among organisms ranging from primary producers to apex predators and from the deep-sea benthos to the coast. Another objective was to develop phytoplankton profiles as baseline for future studies. These data contribute to a food web model used to determine risks to ecosystem structure and function and regional economies following from extreme anthropogenic events (e.g., discharged and background hydrocarbon) and adaptive management strategies.
