A spatial data layer of submerged aquatic vegetation (SAV) in Lake Michigan. This data set comprises a portion of the Environmental Sensitivity Index (ESI) data, which characterizes coastal environments by their sensitivity to spilled oil. It was published by the National Oceanic and Atmospheric Administration (NOAA) and last updated in March 2026.
Use Cases
- Modeling oil spill impact zones based on submerged aquatic vegetation (SAV) locations.
- Assessing coastal environmental sensitivity for planning and regulatory purposes based on ESI framework.
- Analyzing species-specific abundance and seasonality of benthic resources in relation to spatial polygons.
Strengths
- Data is part of the standardized Environmental Sensitivity Index (ESI) framework for oil spill planning.
- Includes relational tables with species-specific attributes like abundance and seasonality.
- Last updated date is explicitly provided: 2026-03 13.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and file size are unknown, which may limit suitability assessment.
- The primary file format is PDF, which may not be ideal for direct geospatial analysis.
