• bathy30  BATHY30 is a raster dataset of bathymetry and intertidal cover types for the Gulf of Maine developed by the U.S. Fish & Wildlife Service; Gulf of Maine Program. Sounding data was used in deeper areas to generate a relatively coarse resolution bathymetry grid. Finer spatial resolution around inshore features were achieved by use of tidal exposure classifications described from aerial photography (e.g., "regularly flooded, irregularly exposed, irregularly flooded") in the USFWS National Wetland Inventory datasets, channels and tidal flats mapped from photography in Maine's Coastal Marine Geologic Environments (CMGE), and Massachusetts orthophoto wetlands maps. These classes were not translated into absolute elevations, but instead were coded as to position within the intertidal zone, and the general cover type (e.g., high marsh, lower intertidal flats, etc.), which may convey useful ecological information. Where near shore subtidal bathymetry were inadequate, the grid was 'patched' using grids developed from scanned NOAA charts. For more information about the USFW Gulf of Maine Program and a CD of data from the Gulf of Maine Watershed Habitat Analysis plus supplemental information about BATHY30 see: http://gulfofmaine.fws.gov/ and http://r5gomp.fws.gov/gom/habitatstudy/metadata/gombathydoc.htm. - Download this layer
  
  
• bathym100  BATHYM100 contains bathymetry lines for the Gulf of Maine at a scale of 1:100,000 showing depth in 10 meter intervals. This dataset was developed by the Maine Geological Survey using USGS 30 X 60 minute series topographic-bathymetric maps. Bathymetric contours are coded with depth in feet (10 meter interval mean lower low water datum) Spatial topology varies from good to poor. - Download this layer
