BLM/OCS Southern California Outer Continental Shelf Environmental Baseline Studies
Data in this file were produced by Science Applications, Inc., prime contractor on the Bureau of Land Management/Outer Continental Shelf - Southern California Studies (BLM/OCS). Data consist of six data files (benthic sediment characteristics, benthic sediment hydrocarbons, intertidal sediment hydrocarbons, intertidal sediment trace metals, benthic sediment trace metals, and intertidal sediment characteristics). Data are derived from 801 grab and box core samples from the sea floor offshore Southern California. Original documentation have been scanned as images to a .PDF document. The data were received on August 19, 1977. Some documentation has been transcribed to an ASCII readme file. Additional data codes and documentation are in poor, extremely hard to read condition. There are known problems in these data files, including truncation of records past the 80th column in the first file (Benthic Sediment Characteristics). Other problems exist in device codes and analyses that were unable to be resolved by multiple exchanges with the contributors. Additional problems may exist, including deviations from the specified formats.

Lineage Statement | Grain size analyses from this data set were not reformatted to the 073 format for addition to the NGDC Seafloor Sediment Grain Size Database due to quality concerns. 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 in September of 1977 on nine track magnetic tape in EBCDIC form as five files of 130 character records blocked to 2600 characters per block. The tape contained 2, 580 records, there were 1,066 sample header records, but all but 801 were duplicated. Francis Mitchel of NODC noted on transmission that the data were probably not usable. |
