gom15ctr: Construction of Digital Bathymetry for the Gulf of Maine

The U.S. Geological Survey is conducting studies of the sea floor geology in the Gulf of Maine and along the New England Shelf that provide geologic framework information for habitat, resource, and environmental studies. This data set provides bathymetric contours for the Gulf of Maine GIS project area. Note: These data were reprojected from their native projection into North American Datum 1983 (NAD83) / Massachusetts State Plane coordinate system, Mainland Zone (Fipszone 2001) meters by the Massachusetts Office of Coastal Zone Management on June 26, 2006.

美国地质调查局（U.S. Geological Survey）正对缅因湾及新英格兰陆架海域开展海底地质研究，为栖息地、资源与环境研究提供地质框架支撑数据。本数据集为缅因湾地理信息系统（Geographic Information System，GIS）项目区域提供水深等值线数据。备注：马萨诸塞州海岸带管理办公室于2006年6月26日将这批数据从原始投影坐标系重投影至1983北美大地基准面（NAD83）/马萨诸塞州平面坐标系本土区域（联邦信息处理标准区域2001）米制坐标系中。
