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 meters (10 meter interval mean lower low water datum). Spatial topology varies from good to poor.
