The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | CTD, water quality, plankton species abundance, and chlorophyll a and b concentrations in sediment samples data collected from R/V Bellows cruise BE-1212 in the northern Gulf of Mexico from 2011-05-21 to 2013-09-16 (NCEI Accession 0175053) |
| Abstract: | This dataset contains conductivity, temperature, depth, water quality, plankton species abundance, and chlorophyll a and b concentrations in sediment samples data collected from R/V Bellows cruise BE-1212 in the northern Gulf of Mexico from 2011-05-21 to 2013-09-16. CTD data were collected from 26 sites from 2012-05-05 to 2012-05-07. In addition, water samples were collected and analyzed for nutrient concentrations at the Wetlands Research Laboratory at the University of West Florida. Quantitative nanoplankton census data were taken via scanning electron microscopy (SEM) to determine after-the-fact, the effects of the Macondo Oil Spill on skeletal (coccolith)-bearing phytoplankton. Plankton samples were collected from 14 offshore shelf sites from 2012-05-05 to 2012-05-07 and abundances were recorded as counts and as percentages of the total sample. Similarly, sediment samples were collected using replicate Shipek sediment grabs from 28 samples sites between 2011-05-21 and 2013-09-16. Sediment was frozen in the field for transfer to the laboratory. Once in the laboratory, samples were acetone extracted and fluorescence was determined on a Perkin Elmer scanning fluorometer. Standard chlorophyll preparations were used for sample quantification. |
