    "descript": "Bathymetric terrain models (BTMs) of seafloor morphology are an important component of marine geological investigations. Advances in technologies of acquiring and processing bathymetric data have facilitated the creation of high-resolution bathymetric surfaces that approach the resolution of those available for onshore investigations. These bathymetric terrain models provide a detailed representation of the Earth's subaqueous surface and when combined with other geophysical and geologic datasets, allow for interpretation of modern and ancient geologic processes. More information about the individual USGS source surveys (if USGS scientists participated in survey) for this grid can be found on the Woods Hole Coastal and Marine Science Center Field Activity webpage: 2002-051-FA: http:\/\/woodshole.er.usgs.gov\/operations\/ia\/public_ds_info.php?fa=2002-051-FA 2003-008-FA: http:\/\/woodshole.er.usgs.gov\/operations\/ia\/public_ds_info.php?fa=2003-008-FA 2003-032-FA: http:\/\/woodshole.er.usgs.gov\/operations\/ia\/public_ds_info.php?fa=2003-032-FA 2005-019-FA: http:\/\/woodshole.er.usgs.gov\/operations\/ia\/public_ds_info.php?fa=2005-019-FA 2006-008-FA: http:\/\/woodshole.er.usgs.gov\/operations\/ia\/public_ds_info.php?fa=2006-008-FA 2007-004-FA: http:\/\/woodshole.er.usgs.gov\/operations\/ia\/public_ds_info.php?fa=2007-004-FA 2013-036-FA: http:\/\/woodshole.er.usgs.gov\/operations\/ia\/public_ds_info.php?fa=2013-036-FA",
