|| Japan Oceanographic Data Center (JODC) Descriptions of Seafloor Sediment
|| This file was compiled by the Japan Oceanographic Data Center using the IOC
Marine Geological Data Format. It includes 748 master records and 1740 data records.
It contains information on unconsolidated sediments and hard rocks from the seafloor,
including station location, collecting institution and ship, date of collection, type
of collecting device, analysis method(s), grain size information, biogenous components,
structure, non-biogenous components, age, sediment color, and remarks. Igneous, sedimentary,
and metamorphic rocks are also noted including encrustations, and erratics. Mass physical
properties are given for sediments, including density, specific gravity of solids,
water content, void ration, porosity, Atterberg limits, activity, cohesion, consolidation,
sensitivity, and acoustic properties. These data are available for direct download
from NGDC's Web site.
