Abstract:
The dataset is representative of 13 research cruises spanning from July 2010 to July 2013. Five cruises set to observe the West Florida shelf, while eight cruises were employed to assess the impact of the BP Oil spill on impacted North Florida shelf sites. West Florida Shelf samples sites (10 sampling sites total) comprised of Southern Transect (ST) line (stations ST03, ST06, ST12, ST18 and ST24), and the Northern Transect (NT) (stations NT31, NT25, NT19, NT13, and NT07). NE Gulf of Mexico sites included 16 sampling sites; DHS01, DSH07-10, Deepwater Horizon (DWH) station, FT1, PCB01-06, PCB11-12, and PCB14. Also included were NELine01 and PP01 stations. This dataset reports microtoxicity data from each site. This dataset has been updated in GRIIDC UDI: R4.x267.000:0046. Associated journal article: John H.

Data Parameters and Units:
The data is presented as a set of Excel files giving the experimental measurements on all of the samples obtained during the C-IMAGE research cruises. These files are accompanied by a PowerPoint file containing graphic illustrations of the raw data. Each of the files is comprised of all the experimental data for a particular assay type. NOTE: Figures and maps found in the publication associated with this dataset (dx.doi.org/10.1021/es401761h) were removed from the files in the dataset. The Excel file QwikLite_summaryallcruisesB&W includes all the measurements using the QwikLite assay (from Assure Controls). This assay uses a light-producing organism to estimate the general toxic effects of a sample on PHYTOPLANKTON in general. parameters (units): Station [sample station (ID)]; Depth [depth from water surface (surface, pore water, or depth in meters)]; QuikLite [percent inhibition of light production in comparison to a negative control(%)]; Range [statistical range of the % light inhibition values (%); Date (MM/DD/YYYY); The Excel files Microtox_All WFSstationsB&W and microtoxSummaryallNGOMcruiseB&Ws1 are the data for the Microtox Assay, which is a proxy for general BACTERIAL toxicity. The assay works similarly to the QuikLite assay in that it measures the light production by a culture and the results are expressed in the same units. parameters (units): Station [sample station (ID)]; Depth [depth from water surface (surface, pore water, or depth in meters)]; Microtox [percent inhibition of light production in comparison to a negative control (%)]; Range [statistical range of the % light inhibition values (%); Date (MM/DD/YYYY); 4) The Powerpoint file MicrtoxQuikMicroscreen mapsold is a visual representation of the data from the above files.
