Contribute Data:NCEI accepts new multibeam bathymetric data. We prefer data in a format supported by the MB-System software package developed at Lamont-Doherty Earth Observatory (LDEO). When submitting data, you will be asked to enter metadata for each survey. Data should be organized by survey, tarred, and compressed for upload. Search the Bathymetric Data Viewer to determine whether your surveys are not already in the MBBDB. There is a 2 GB limit. |
