World Data Center for Marine Geology & Geophysics
Descriptions, Photographs, and Analyses of Marine and Lakebed Sediments and Rocks
NGDC archives hundreds of digital data files and analog data sets (paper, film, etc.) containing descriptions and analyses of marine and lacustrine sediment and rocks from the sea floor. Data are compiled from U.S. institutions and from international sources through exchange mechanisms including the World Data Center system.
The Index to Marine & Lacustrine Geological Samples provides searches of sea floor and lakebed cores, grabs, dredges, and drill samples available directly from participating oceanographic institutions. |
