Seafloor Surficial Sediment Descriptions (Deck41)

NGDC Data Set G02094

World Data Service for Geophysics, Boulder

The NGDC "Deck41" database contains surficial sediment descriptions for over 36,000 seafloor samples worldwide.

Data include collecting source, ship, cruise, sample id, latitude/longitude, date of collection, water depth, sampling device, dominant lithology, secondary lithology, and a brief description of the surficial sediment at the location.

This data file is fully searchable online as a standalone data file. Searches return data for onscreen viewing, and offer data exports in a tab-delimited form suitable for upload into most spreadsheet and database applications.

Data Set Credit

The file was begun by the Marine Geology and Geophysics group of the National Oceanographic Data Center (NODC) in the early 1970s and transferred to NGDC in 1975 when the group moved to Boulder, Colorado.

All data were abstracted and coded by the old NODC Marine Geology and Geophysics group, primarily from corelogs, laboratory analysis sheets, and unpublished reports contributed by individuals and oceanographic institutions and agencies worldwide.
