Fire Island Shoreline Position Data from 1979 to 2024

Mean high-water shoreline positions collected at Fire Island National Seashore between 1979 and Fall 2024. The data were assembled by the Northeast Coastal & Barrier Inventory and Monitoring Network's Ocean Shoreline Position Monitoring Program. Surveys were conducted by vehicle or walking along the high tide swash line, with GPS recording positions at least every 10 meters.

Use Cases

• Modeling shoreline change rates based on repeated position measurements over time.
• Analyzing coastal erosion patterns based on the high tide swash line data.
• Assessing storm impact on beach morphology based on shoreline position shifts.
• Monitoring long-term geomorphic trends for coastal management based on the 45-year time series.

Strengths

• Data spans a 45-year time range from 1979 to Fall 2024.
• Shoreline positions were recorded at high spatial resolution, with GPS points collected at least every 10 meters.
• Surveys cover multiple shoreline types, including ocean, inlet, and bay shorelines.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Some surveys collected prior to 2003 do not contain FGDC-compliant metadata records.
• Row count is unknown, which may limit suitability assessment.
