Ice-Rafted Sediment Hydrodynamics in Plum Island Sound

Plum Island Sound, Massachusetts, is the location for this dataset of hydrodynamic results from an extratropical storm between January and July 2018. It contains modeled or measured water levels, inundation depths, and flow direction and speed, linked to observations of ice-rafted sediment deposits. The data supports analysis of coastal storm impacts and sediment transport processes on a marsh surface.

Use Cases

• Modeling storm surge inundation based on water level and depth data
• Analyzing sediment transport pathways based on flow direction and speed
• Studying the impact of ice-rafting events on coastal marsh morphology
• Validating hydrodynamic models (e.g., Delft3D) for extratropical storms

Strengths

• Provides a temporally specific record of a storm event from 2018-01-26 to 2018-07-03
• Links hydrodynamic variables (flow, water level) directly to physical sediment deposits, enabling process-based study
• Cross-platform presence on NASA EarthData and Data.gov signals importance and accessibility

Limitations

• Column names and data structure are not specified in any source, hindering precise understanding of the data format
• Conflicting 'last updated' dates (2018 and 2026) across sources create uncertainty about data currency or versioning
• Key metadata such as row count, file size, and license are uniformly absent
