Long Island Sound Total Organic Carbon Sample Locations

Point data from the U.S. Geological Survey maps the precise locations of surficial sediment samples collected for Total Organic Carbon (TOC) analysis in Long Island Sound. This geospatial layer was created to support the development of a TOC distribution map for the estuary. The data was published by the USGS in 1998 as part of Open-File Report 00-304.

Use Cases

• Analyze the spatial distribution of TOC sampling stations to identify coverage gaps in Long Island Sound.
• Use the point locations as a reference layer to validate or interpret the associated TOC polygon map (listoc).
• Correlate sample station coordinates with other marine datasets for multi-parameter environmental analysis.

Strengths

• Data originates from the authoritative U.S. Geological Survey (USGS).
• Provides a foundational geospatial reference for a specific scientific study and map product.

Limitations

• The dataset is temporally stale, with no updates since its publication in 1998.
• Sample count, specific TOC measurements, and other columnar data are unavailable in this layer.
