2003 data contains internal wave packets digitized from Synthetic Aperture Radar (SAR) imagery and intersected with tidal zones for Massachusetts Bay. The feature class was created by the National Oceanic and Atmospheric Administration's Office of Coastal Survey. The internal wave packets were digitized at a 1:350,000 scale.
Use Cases
- Analyzing the spatial distribution of internal wave packets relative to digitized tidal zones.
- Modeling the interaction between internal wave features and coastal bathymetry using georeferenced SAR data.
- Validating numerical ocean models by comparing simulated internal waves with observed packet locations and shapes.
Strengths
- Data integrates two distinct geospatial layers: digitized internal wave packets and NOAA tidal zones.
- Internal wave features were digitized at a defined cartographic scale of 1:350,000.
Limitations
- Dataset is temporally stale, with a last update date of September 2003.
- Sample size and spatial resolution of the digitized packets are unknown.
- Geographic coverage is limited to Massachusetts Bay.
