Featured sample collections: The Marine Geoscience Data System (MGDS) sample metadata

November 2012

Sample metadata from the Marine Geoscience Data System (MGDS) have been migrated into SESAR as part of the consolidation of sample cataloging within the Integrated Earth Data Applications (IEDA) facility. MGDS provides access to data portals for the NSF-supported Ridge 2000 and MARGINS, and GeoPRISMS programs, the Antarctic and Southern Ocean Data Synthesis, and the Academic Seismic Portal. There are over 14,000 sample metadata profiles registered with IGSNs under the namespace MGD.

Use the SESAR Catalog Search Advanced Search options to find metadata profiles of specific cruises, platforms or collectors.

Investigators that own the physical samples in the MGD collection are encouraged to register an account with SESAR, which will enable them to organize their samples under their own workspace, edit metadata profiles, and directly register additional sample metadata. Please contact us at info@geosamples.org if you would like to transfer your sample metadata from the MGDS ownership into your own account.

US Extended Continental Shelf Project to Use IGSNs

January 2011

Geological samples collected as part of the U.S. Extended Continental Shelf (ECS) Project will be registered with SESAR and will receive IGSNs, as outlined in the U.S. ECS Policy for Data, Publications, and Physical Samples. SESAR is working with the data management team of the U.S. Extended Continental Shelf (ECS) Project at the National Geophysical Data Center (NGDC) to develop an ISO standard based metadata template for geologic bottom sample information that will meet the needs for the U.S. ECS efforts and for the UNOLS and IODP requirements. The template will be developed under the leadership of the ECS data management team at NGDC and in coordination with LDEO as the academic lead and will align with data description standards in use for both the SESAR and IODP efforts.

The U.S. Extended Continental Shelf (ECS) Project is a multi-agency collaboration whose goals are to determine and define the extent of the U.S. continental shelf beyond 200 nautical miles (nm).
