AB: With funding from the U.S. National Science Foundation Office of Polar Programs, the Antarctic Multibeam Bathymetry Synthesis (AMBS, http://www.marine-geo.org/antarctic/) is an integrated web-accessible bathymetry and geophysical database for the Southern Ocean and Antarctica, serving data from the US research vessels Nathaniel B. Palmer and Laurence M. Gould, amongst others. Interdisciplinary polar data can be downloaded for free through the Data Link web browser interface (http://www.marine-geo.org/link/) which enables keyword searches by data and instrument type, geographical bounds, scientist, expedition name and dates. The free, platform-independent data visualization tool GeoMapApp (http://www.geomapapp.org/) supports dynamic exploration of a wide range of data sets on a Global Multi-Resolution Topography (GMRT) synthesis, including the polar regions, allowing users to generate custom grids and maps and import their own data sets and grids. A specialised polar stereographic map projection incorporating multibeam swath bathymetry and the BEDMAP under-ice seafloor topography is available for the Southern Ocean. The GMRT global digital elevation model is served freely as a Web Map Service layer and is available for viewing with OGC-compliant clients including Google Earth (http://www.marine-geo.org/Data4GoogleEarth.html). To promote interoperability and data sharing, we are working with research partners including the Marine Metadata Interoperability (MMI) project and the National Geophysical Data Center to develop standardised metadata and best practices that comply with existing FGDC and ISO standards. We are also taking on the US Antarctic Data Coordination Center function, assisting NSF-funded investigators in documenting and archiving their data in accordance with the IPY Data Policy.
