Coverage is worldwide. Data sources include both US and foreign oceanographic institutions and government agencies. 3) MGG Contributions and RIDGE Multibeam Synthesis http://ocean-ridge.ldeo.columbia.edu/general/html/home.html RidgeMBS provides access to shaded relief maps, bathymetry grids and multibeam bathymetry field data from the world's mid-ocean ridges. This effort was initiated in 1993 with the support of the National Science Foundation (NSF)-sponsored RIDGE and Ridge 2000 programs. 4) SIO Multibeam http://nsdl.sdsc.edu/ Data, documents and images from 822 expeditions by the Scripps Institution of Oceanography (SIO) since 1903 are becoming web-accessible under a usage policy through the new SIOExplorer project, and will become part of the overall NSF-funded National Science Digital Library (NSDL). The effort is a collaboration among researchers at Scripps, computer scientists from the San Diego Supercomputer Center (SDSC), and archivists and librarians from the UCSD Library. 5) NGA Digital Nautical Soundings Global soundings for depth < 300 m. Because of the proprietary nature of some of these soundings, their source and location has not been encoded in the source ID files (SID) but they have been used to construct the grids. 6) JAMSTEC Multibeam - JAMSTEC Data Site for Research Cruises http://www.jamstec.go.jp/cruisedata/e/ JAMSTEC operates research vessels and submersibles for various area and objectives. At this site JAMSTEC disseminates the data and samples that have been obtained via its research cruises. Cruises are arranged in vessels, years and cruise codes. Links to the page for each data and sample are posted on the related cruise page. This site posts the data and samples from JAMSTEC fleets; Natsushima, Kaiyo, Yokosuka, Kairei and Mirai, and submersibles operated on these vessels. Data and samples from submersibles are found on the data page of the related vessel. 6) IBCAO Grid (latitude > 80 deg) http://www.ibcao.org/ Jakobsson, M., Macnab, R., Mayer, M., Anderson, R., Edwards, M., Hatzky, J., Schenke, H-W., and Johnson, P., 2008, An improved bathymetric portrayal of the Arctic Ocean: Implications for ocean modeling and geological, geophysical and oceanographic analyses, v. 35, L07602, Geophysical Research Letters, doi:10.1029/2008GL033520 7) NOAA Coastal Grids http://www.ngdc.noaa.gov/mgg/fliers/04mgg01.html The National Geophysical Data Center is addressing the need for topographic-bathymetric relief models that integrate land and seafloor elevations by assembling a gridded database which merges the US Geological Survey 3-arc-second DEMs with a vast compilation of hydrographic soundings collected by the National Ocean Service and various academic institutions. Eight CD-ROMs are available covering the US East, Gulf, and West Coasts (see above). In addition to the US Geological Survey and National Ocean Service data, volumes 3 through 5 also include bathymetric contours from the International Bathymetric Chart of the Caribbean Sea and the Gulf of Mexico project. These eight volumes, plus volumes 9 and 10 (Puerto Rico and Hawaii) are also available on one DVD-ROM. All volumes are also available for free download. 8) IFREMER http://www.ifremer.fr/anglais/program/progi.htm Centerbeam of IFREMER cruises. 9) CCOM High resolution bathymetry of US outer continental Shelf http://ccom.unh.edu/index.php?p=50|55|63&page=unclos/data.php CCOM, 2008.

In these water depths satellite-based imagery cannot routinely be used for mapping, vessel-based acoustic systems must be employed instead. Acoustic mapping systems provide high resolution depth information, and the acoustic response can be analyzed to extract information about the seabed’s character, e.g. roughness or hardness. 12) GLOBEC http://www.whoi.edu/science/PO/so_globec/SO_GLOBEC_bathy.html One objective of the SO GLOBEC program is to produce a better knowledge of the sea floor bathymetry in the program study area. Much of Marguerite Bay and the adjacent shelf was poorly charted when the program was started in 2000, so we first created a local area improved version (ETOPO8.2A) of the Sandwell and Smith ETOPO2 2-min digital gridded bathymetry for the SO GLOBEC study area. The first SO GLOBEC mooring cruise on the R/V Lawrence M. Gould in March 2001 quickly showed that the 2-min resolution of ETOPO8.2A does not resolve many of the canyons and abrupt changes in topography which characterize Marguerite Bay and the inner- to-mid shelf region, nor is it particularly accurate in even the more uniform terrain regions. 13) GEBCO http://www.bodc.ac.uk/data/online_delivery/gebco/ This grid uses ENC data around India as well as some GEBCO contours in the Weddell Sea. 14) NAVOCEANO Soundings High resolution grids around Hawaii. 15) 3DGBR Sure David, the current reference for the gbr100 grid can be seen at the top of the download page at: http://deepreef.org/bathymetry/65-3dgbr-bathy.html But here is the reference in full: Beaman, R.J., 2010.

One of the most accurate ways of collecting bathymetry data is through the use of multibeam echosounders which are acoustic ship-borne instruments designed to map the ocean floor. Geoscience Australia is the national custodian of an extensive multibeam dataset. Along with the multibeam data collected by the Australian Government, Geoscience Australia also holds numerous datasets that have been submitted from other institutions in the international scientific community and that lie within and around Australian waters. Geoscience Australia is releasing this data to facilitate the use of, and access to, bathymetry data in the wider mapping community. This dataset is a tiled compilation of all the multibeam data held by Geoscience Australia lying within the outer edge of the offshore area of Australia, as well as some data in international waters, as at August 2012. The data is gridded to a resolution of 50 metres, which allows for a significant amount of detail to be seen. The data is also projected into suitable WGS84 UTM zones.
