Along with this publication, two Google Tours were released highlighting Seafloor Features and Ridge 2000 Science. Both tours are being featured in the Google Earth Showcase and on the Google Earth YouTube Channel. The GMRT Synthesis would not be possible without the contributions of hundreds of scientists whose data has been made publicly available. The full GMRT attribution layer which provides links to source data can also be downloaded as a kmz file from the Google Earth Gallery.

Likewise, the Ridge 2000 Tour would not have been possible without the contributions of several members of the Ridge 2000 Community including Chuck Fisher, Deb Kelley, Tim Shank, Joe Resing, Dan Fornari, Tim Crone, Scott White, Veronique Robigou, and Liz Goehring. In addition to the Ridge 2000 Tour, several Ridge 2000 images and videos already available in the Ridge 2000 Media Bank have been posted to the Google Earth Explore the Oceans Layer.

New Help Pages for the Ridge 2000, MARGINS, and GeoPRISMS Custom Search Interfaces were released along with a Survey to solicit feedback from the user communities. The survey will be open until June 30.

GeoMapApp 3.0 and GMRT 2.0 released! GeoMapApp 3.0 provides access to a major upgrade to the base topography dataset accessible through GeoMapApp to include the GMRT 2.0, with greatly expanded coverage in the oceans, and the ASTER and NED topography datasets for the global land masses. The ASTER GDEM topography dataset (Japan METI/NASA), provides 30 m resolution for the continents from 83°S to 83°N and replaces the SRTM dataset used in prior GeoMapApp releases. For North America, the even higher resolution NED dataset (USGS) is now accessible, providing topography of the continental U.S. to 10 m resolution. For the oceans, the GMRT v2.0 synthesis includes bathymetric coverage to 100 m resolution from multi-beam bathymetry mapping expeditions and regional gridded compilations from a number of areas and international sources. New data coverage over GMRT 1.0 is focused in the Atlantic and central Pacific with over 100 expeditions added since the prior release. In addition, GMRT v2.0 includes a new 50 m grid resolution layer for the continental shelves and other ocean areas where native resolution of the available sonar data is sufficient. The high resolution bathymetry are merged with the Smith and Sandwell v12.1 global topography compilation, the IBCAO v2.23 for the Arctic, and the BedMap Subglacial Topographic Model of the Antarctic.

Statistics showing the use of GeoMapApp Custom Portals since 2004 are now available.
