April 2005

High-resolution grids for Papua New Guinea were added to GeoMapApp bathymetry synthesis and are also available through the database.  Grids were contributed by David Naar and derived from EM-3000 swath data from cruises VANC27MV, VANC28MV, VANC30MV. Gridded data from the Tonga trench collected on BMRG08MV (Bloomer and Wright) now available.

March 2005

Data resources for each Focus Site now include a listing of links to other relevant data sources.

Added bathymetry data to GeoMapApp from several historical cruises with crossings in the Gulf of California region (AT03-46, MOCE05MV, PHNX03MV). Also added bathymetry data for region from EW0210 contributed by Dan Lizarralde.

Bathymetry for the Costa Rica margin from EW0005 (from Kirk McIntosh) now incorporated in GeoMapApp.

February 2005

Edited bathymetry for EW0202 and EW0203 from the IBM site received from Andrew Goodliffe and incorporated in GeoMapApp.
