Polycyclic aromatic hydrocarbons (PAHs) are reported for water samples collected from the San Lorenzo River water during the rainy seasons from 2015 to 2016. Samples were collected during 2-, 5- and close to 10 year flood events.

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. 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.

A series of Natural Resource Damage Assessment (NRDA) cruises were conducted in 2010 and 2011 to evaluate the distribution and densities of ichthyoplankton and other zooplankton in Gulf of Mexico waters potentially affected by the Deepwater Horizon Oil Spill (DWHOS) and in surrounding areas. This dataset includes larval fish (family: Paralepididae) diet and stable isotope data from samples collected on NRDA plankton and NRDA Nekton surveys, 2010-2011. It includes data for ichthyoplankton specimens (taxonomic identification, length, weight, stable carbon and nitrogen values, compound specific amino acid values) and their corresponding diets (prey taxonomic identification, number of individuals, length, weight).

The Ecotox Program is at the forefront, nationally and internationally, of targeted research to characterize the impacts of petroleum hydrocarbons on NOAA trust resources, particularly fish early life stages. This work is extending lessons learned from the Exxon Valdez oil spill in Alaska, through the Cosco Busan spill in San Francisco Bay, to an array of current and intensive activities associated with the Deepwater Horizon natural resource damage assessment in the Gulf of Mexico. This research has been particularly influential in recent years (PNAS papers in 2011 and 2012), with major Deepwater papers forthcoming in 2012 and 2013. Funding has come from NOS/ORR, the Oiled Wildlife Care Network, the Prince William Sound Regional Citizen's Advisory Council, the San Francisco Estuary Institute, and other sources. Ecotox is currently developing new tools to assess PAH exposure and toxicity in fish and other animals, with national applicability - e.g., in advance of anticipated oil drilling in the Arctic, beginning in the summer of 2012. 3 year study of effects of the Cosco Busan oil spill. Morphology, heart rate, hatching rate data of Pacific herring planted at oil and reference sites and correlating herring spawns at these sites. This work supports NOAA’s Damage Assessment, Remediation, and Restoration Program (DARRP).

The standardized NEFSC Sea Scallop Survey began in 1980 and has covered an area from Cape Hatteras to Georges Bank. The survey aims to determine the distribution and abundance of scallops and associated fauna utilizing two sampling devices: the 8-foot wide New Bedford style dredge, standardized sea scallop dredge and the stereo-optic towed camera array (HabCam). Fifteen minute dredge hauls are made at stations that are randomly selected using the NEFSC shellfish strata to provide unbiased abundance measurements. The HabCam is conducted using transects across bathymetry lines in the same area as the dredge tows. Various vessels have served as a platform for the survey, including NOAA vessels: FRV Albatross IV, FRV Oregon II, FRV Chapman, FV Tradition and currently, the UNOLS vessel RV Hugh R. Sharp.

This dataset contains CTD, plankton species relative abundance, and quantitative phytoplankton profiles data collected from 9 sites off the Florida Panhandle at the head of DeSoto Canyon, Gulf of Mexico aboard the R/V Bellows cruise BE-1307 from 2012-10-13 to 2012-10-15. 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.

This dataset contains oceanographic and surface meteorological data in netCDF formatted files, which follow the Climate and Forecast metadata convention (CF) and the Attribute Convention for Data Discovery (ACDD). Sanibel-Captiva Conservation Foundation River, Estuary and Coastal Observing Network, collected the data from their in-situ Redfish Pass station in the Coastal Waters of Florida, Gulf of Mexico, and North Atlantic Ocean. Southeast Coastal Ocean Observing Regional Association (SECOORA), which assembles data from Sanibel-Captiva Conservation Foundation River, Estuary and Coastal Observing Network, and other sub-regional coastal and ocean observing systems of the Southeast United States, submitted the data to NCEI as part of the Integrated Ocean Observing System Data Assembly Centers (IOOS DACs) Data Stewardship Program. NCEI updates this dataset when new files are available.
