NOAA_NCEI Accession 0195411 contains nitrogen and carbon content and stable isotope ratios from sediment core, surface sediment, and suspended particle samples. Data was collected in the Fowl River Watershed at four priority marsh spits and one downstream reference site. Analysis was performed by the U.C. Davis Stable Isotope Facility using continuous flow isotope ratio mass spectrometry.
Use Cases
- Analyze nitrogen and carbon stable isotope ratios to trace sources of nutrient pollution in the watershed.
- Compare % N and % C content between sediment core samples and suspended particles to assess sediment deposition dynamics.
- Evaluate anthropogenic influences by correlating isotope data from priority marsh spits with downstream reference site samples.
- Model marsh health recovery by tracking changes in sediment carbon content across different sample types.
Strengths
- Data includes multiple sample types: sediment cores, surface sediments, and suspended particulate matter.
- Analysis performed by a specialized facility, the U.C. Davis Stable Isotope Facility, using mass spectrometry.
Limitations
- Specific row count, column names, and file formats are unknown.
- Data collection time range and exact geographic coordinates are not provided.
- Last update was in 2018, indicating the dataset is not recent.
