Gateway National Recreation Area Shoreline Position Data, 2008-2024

A series of mean high water shorelines collected at the Gateway National Recreation Area's Plumb Beach section between Spring 2008 and Spring 2024. The data were assembled by the Northeast Coastal & Barrier Inventory and Monitoring Network's Ocean Shoreline Position Monitoring Program. Shoreline positions were recorded via GPS/GNSS at intervals of at least one point every 10 meters along the high tide swash line.

Use Cases

• Modeling shoreline change rates based on the series of high tide line positions.
• Analyzing coastal erosion and accretion patterns based on the recorded shoreline features.
• Assessing the impact of storms and seasonal changes on beach morphology based on the wet/dry sand line data.
• Monitoring long-term geomorphological trends in a recreational coastal area based on the 16-year time series.

Strengths

• Data collection spans 16 years, from Spring 2008 to Spring 2024.
• Shoreline positions were recorded at high spatial resolution (at least one point every 10 meters).
• Data are part of a formal monitoring program (Ocean Shoreline Position Monitoring Program).

Limitations

• Some surveys prior to 2003 lack FGDC-compliant metadata records.
• Row count and specific column definitions are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
