    "descript": "These data were collected under a cooperative agreement with the Massachusetts Office of Coastal Zone Management (CZM) and the U.S. Geological Survey (USGS), Coastal and Marine Geology Program, Woods Hole Science Center (WHSC). Initiated in 2003, the primary objective of this program is to develop regional geologic framework information for the management of coastal and marine resources. Accurate data and maps of sea-floor geology are important first steps toward protecting fish habitat, delineating marine resources, and assessing environmental changes due to natural or human impacts. The project is focused on the inshore waters of Massachusetts, primarily in depths between 3 and 30 meters. Data collected for the mapping cooperative have been released in a series of USGS Open-File Reports (https:\/\/woodshole.er.usgs.gov\/project-pages\/coastal_mass\/). This spatial dataset is from the study area located in northern Cape Cod Bay, and consists of high-resolution geophysics (bathymetry, backscatter intensity, and seismic reflection) and ground validation (sediment samples, video tracklines, and bottom photographs). The data were collected during five separate surveys conducted between 2003 and 2008 (USGS-WHSC surveys 06012 in 2006; 07001, 07002, and 07003 in 2007; and 08002 in 2008) and cover more than 480 square kilometers of the inner continental shelf. More information about the individual USGS surveys that are were conducted as part of the northern Cape Cod Bay project can be found on the Woods Hole Coastal and Marine Science Center Field Activity webpages: 06012: https:\/\/cmgds.marine.usgs.gov\/fan_info.php?fa=2006-012-FA 07001: https:\/\/cmgds.marine.usgs.gov\/fan_info.php?fa=2007-001-FA 07003: https:\/\/cmgds.marine.usgs.gov\/fan_info.php?fa=2007-003-FA 07002: https:\/\/cmgds.marine.usgs.gov\/fan_info.php?fa=2007-002-FA 08002: https:\/\/cmgds.marine.usgs.gov\/fan_info.php?fa=2008-002-FA",

Assessments include evaluations of present ecological or economic values of substrate distributions, drivers of substrate change, and functions of substrates. Predictions are the results of models or projections of future substrate distributions, values, or ecological impacts, including predicted substrate changes due to natural and human forces including erosion, accretion, sea-level change, extraction, trawling, or other factors; and they are the results of scenario-based models of substrate changes on ecological or economic values under different management strategies or other human alterations."
