Boston Harbor Bathymetry Boundary Polygon

Approximately 170 square kilometers of seafloor data were collected for Boston Harbor and its approaches. The National Oceanic and Atmospheric Administration Ship Whiting gathered sidescan sonar and bathymetric measurements in 2000 and 2001. The Massachusetts Office of Coastal Zone Management and the U.S. Geological Survey reprocessed and gridded the data.

Use Cases

• Delineate the spatial extent of high-resolution bathymetric surveys for project planning using the boundary polygon.
• Integrate the boundary with other geospatial layers to analyze seafloor characteristics within the surveyed area.
• Use the polygon to clip or mask broader regional datasets, focusing analysis specifically on the Boston Harbor approaches.

Strengths

• Covers approximately 170 square kilometers of seafloor.
• Data was collected by a NOAA survey vessel and reprocessed by multiple government agencies (NOAA, USGS, MA CZM).

Limitations

• Data collection occurred over 20 years ago (2000-2001), limiting contemporary analysis.
• Specific data formats, row counts, and column details are unknown.
• The dataset appears to be a single boundary polygon, not the underlying bathymetric measurements.
