National Marine Fisheries Service Grain Size Data from the Baltimore Canyon Trough

browse graphicsample locations in study area
Grain size analyses produced by Robert Reid of the NOAA National Marine Fisheries Service for the NOAA/BLM Outer Continental Shelf Mid-Atlantic Project, Baltimore Canyon Trough Area. Grain size analyses were originally contributed in the historic NODC 003 format for 113 sea floor samples collected from May 22-27, 1974 by the Mt. Mitchell on cruise BC7401. 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.

Lineage information for: dataset
Lineage Statement These data were contributed by the originator to NOAA's former National Oceanographic Data Center (NODC) and may be part of a larger compilation archived as oceanographic data by NCEI. Data were received from NODC in the historic 003 format and translated to the 073 grain size format and added to the digital grain size database. Data were received on nine track magnetic tape in ASCII form, record size 109, blocking 9592 characters/block, as two files: 1) tape label; 2) 003 sediment data for cruise BC7401, the NODC unique identifier assigned was TR3655.

Processing Steps
  • 2015-04-22T00:00:00 - 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.
