MARGINS and National Marine Sciences Seismic
Reflection Databases Up And Running
A MARGINS database proposal was funded at the MARGINS-NSF Panel in Spring 2003. Bill Ryan and Suzanne Carbotte (Lamont-Doherty Earth Observatory) are the lead investigators, working with David Becker, IODP-TAMU. Also impacting MARGINS was funding of an NSF-MG&G collaborative proposal with Tom Shipley, Suzanne Carbotte, and John Diebold for seismic databasing, which will be integrated with the MARGINS-specific efforts.
In the short time since funding was released for the MARGINS database, the scientists have focused on developing user-friendly front ends and on maximum inter-operability with existing and developing databases that are relevant to MARGINS. They have built in many tools that make the database very useful for visualizing and evaluating a wide variety of data types. They are now working to populate the database, with an initial emphasis on metadata for MARGINS cruises and expeditions. Other data types include underway navigation, bathymetry, gravity, magnetics, multibeam data, SCS and MCS (through the seismic databases at UTIG and LDEO), seismicity, and seafloor isochron data. The MARGINS database will be interoperable with UTIG’s Seismic Reflection database, PetDB, GeoRoc, Navdat, and ODP’s Janus databases.
The University of Texas Institute for Geophysics (UTIG) has been working with the Lamont-Doherty Earth Observatory (LDEO) to construct a seismic reflection and OBS database (National Marine Sciences Seismic Data System) with more specialized capabilities than the MARGINS database. The data system will couple the LDEO Field Data Center’s new and archive field data, with the UTIG Processed Data Center’s processed seismic data, derived products, and related information. To date, data from over 100 cruises have been archived to the new data system.
The developing databases are active and may be accessed online:
UTIG Seismic Database
For NSF-MARGINS-funded scientists, cruise/expedition metadata should be archived within 60 days of the end of the field experiment, and data should be archived within two years. Digital metadata forms are now available for downloading from the MARGINS database website and should be used by all MARGINS funded PIs during their field programs.
The full MARGINS data policy is available online.
For inquiries about archiving data (except MCS) contact Suzanne Carbotte or Bill Ryan.
For MCS data archival inquiries, contact Tom Shipley.
Any comments or suggestions about the functionality of the databases should be sent to the same people.
Comments on policy issues relating to, or arising from, database developments should be sent to Suzanne, Bill or Tom, with cc’s to U.S. MARGINS Chair Doug Wiens and MARGINS Director Paul Wyer.
