USGS Open-File Report 00-304 provides a polygon overlay GIS layer depicting the regional distribution of Total Organic Carbon (TOC) in Long Island Sound sediments. The data represent the only regional TOC study of the area and were originally published in USGS Open-File Report 98-502. The layer was created by the USGS and disseminated in March 1998.
Use Cases
- Analyze sediment TOC concentration patterns across Long Island Sound using polygon attribute values.
- Model relationships between sediment carbon content and other environmental variables using the geospatial overlay.
- Create regional maps of organic carbon distribution for environmental assessment reports.
- Compare historical sediment TOC levels from this 1998 study with contemporary measurements.
Strengths
- Provides the only regional total organic carbon study for Long Island Sound.
- Data were published by the authoritative USGS (United States Geological Survey).
Limitations
- Data is from a single study conducted and published in 1998, representing a historical snapshot.
- Specific data metrics like row count, column names, and sample size are unknown.
- The original data format and specific measurement methods are not detailed.
