Interpreted Seafloor Physiography from Nahant to Gloucester

Coastal seafloor physiographic zones between Nahant and Gloucester, Massachusetts, are characterized from NOAA nautical charts and aerial photographs. The dataset was created by SCIOPS and last updated in 2003. It focuses on inshore areas not covered by other high-resolution geophysical surveys.

Use Cases

• Classify seafloor zones based on interpreted physiographic features from nautical charts.
• Analyze coastal geomorphology by integrating this interpreted data with other bathymetric surveys.
• Map inshore marine habitats using the characterized physiographic zones as a base layer.

Strengths

• Data reprojected to a standardized coordinate system (NAD83/Massachusetts State Plane) in 2006.
• Focuses on inshore areas not covered by specific high-resolution surveys (RAFA03007, RAFA04002).

Limitations

• Data is from 2003 and may not reflect recent coastal changes.
• Specific row counts, column details, and sample sizes are unknown.
• Relies on interpretation of nautical charts and photos, not direct sensor measurements.
