Multibeam Data Stewardship for the US Academic Research Fleet

  • Multibeam Advisory Committee (MAC) promotes best practices, cookbooks, and resources for multibeam data acquisition.
  • Rolling Deck to Repository (R2R) Program provides fleet-wide management of underway data to ensure preservation of, and access to data acquired with the US Academic Research Fleet.
  • Data Resources

  • Marine Geoscience Data System (MGDS) a trusted data repository that provides free public access to a curated collection of marine geophysical data products and complementary data related to understanding the formation and evolution of the seafloor and sub-seafloor.
  • NOAA National Centers for Environmental Information (NCEI) multibeam archive.
  • IHO Data Centre for Digital Bathymetry (IHO DCDB) consists primarily of unedited single and multibeam bathymetric data contributed by industry, government, academia, and crowdsource efforts. These data are a public resource that are routinely used to produce improved, regional and global bathymetric maps and grids in support of science and exploration.
