The Fate of Carbon in Alaskan Landscapes (FOCAL) project by the U.S. Geological Survey collected soil data from central Alaska. The dataset likely contains field descriptions, bulk density, particle size distribution, moisture content, carbon and nitrogen concentrations, isotopic data, and elemental concentrations from sites of varying ages and soil drainage types. The summary was provided by the USGS.
Use Cases
- Model soil carbon storage based on carbon concentration data
- Analyze the relationship between soil drainage and elemental concentrations
- Study post-fire recovery in boreal forests based on site age data
- Correlate soil moisture content with bulk density measurements
Strengths
- Data includes multiple soil properties such as carbon concentration, nitrogen concentration, and isotopic data
- Sites are selected across a range of ages and soil drainage types for comparative analysis
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
Provenance
- Source
- U.S. Geological Survey Fate of Carbon in Alaskan Landscapes (FOCAL) project
- Collection Method
- Field sampling and laboratory analysis of soils from selected sites
- Geography
- Central Alaska, specifically near Delta Junction
