Southwest Florida Shelf Ecosystems Analysis Study

browse graphicsample locations in study area
The Southwest Florida Shelf Ecosystems Analysis Study produced grain size analyses in the historic 073 format for 299 sea floor samples collected from October 25, 1980 to February 15, 1982 by the Venture during cruises ECO0-3 in the Southwest Florida Continental Shelf in the Gulf of Mexico. Data include collecting institution, ship, cruise, sample id, latitude/longitude, date of collection, water depth, sampling device, method of analysis, sample weight, sampled interval, raw weight percentages of sediment, within a given phi range. Some samples also have percentages of total gravel, sand, silt, clay, and statistical measurements such as mean, median, skewness, kurtosis, and standard deviation of grain size. These data are part of the larger NGDC digital grain size database.

Use Constraints
  • While every effort has been made to ensure that these data are accurate and reliable within the limits of the current state of the art, NOAA cannot assume liability for any damages caused by any errors or omissions in the data, nor as a result of the failure of the data to function on a particular system. NOAA makes no warranty, expressed or implied, nor does the fact of distribution constitute such a warranty.

Source Datasets
Lineage Statement Data were received directly from Woodward-Clyde in fixed-field 073 form. Cruise identifiers and sequence numbers were added to this version, no other errors were found, so data were uploaded to the NGDC Seafloor Sediment Grain Size Database.
Processing Steps
  • NOAA created the National Centers for Environmental Information (NCEI) by merging NOAA's National Climatic Data Center (NCDC), National Geophysical Data Center (NGDC), and National Oceanographic Data Center (NODC), including the National Coastal Data Development Center (NCDDC), per the Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235. NCEI launched publicly on April 22, 2015.
