Scripps Institution of Oceanography Geological Collections

Web Page:


SIO, one of the first US institutions to undertake large-scale collection of sediment cores, has historically been a leader in core curation. The Sediment Core collection contains samples collected from as early as 1916. Today, the Cored Sediment Collection is a growing archive of sea-floor samples and associated data supporting a diverse variety of scientific research. The SIO geological collections are supported, in part, by the National Science Foundation.


The cored sediment collection is located in the Deep Sea Drilling Building-West, Rooms 55. 81B, 82, 83, and 91. The dredge collection is also located in Seaweed Canyon, Butler Building T-25.

Sample Collection

The SIO collection contains nearly 6,600 cores (15,000 refrigerated core sections) collected using gravity, piston, trigger, vibra- and box-coring techniques. It is the largest collection in the US (outside that of the Ocean Drilling Program) of sediments from the Pacific Ocean and also contains extensive material from the other major ocean basins.
The SIO dredged rocks collection consists of more than 3,500 dredge hauls and related archive materials. The collection includes rocks from a wide variety of physiographic provinces located throughout the Pacific, Indian, and Atlantic Oceans. All major tectonic features, including hot spots, island chains, seamounts, and abussal plains are represented and rock types include drowned coral reef rocks, ice-rafted rocks, and manganese nodules, as well as very rare igneous, metamorphic, and mantle rocks.
