Antarctic Sediment Core Grainsize and Carbon-Nitrogen Data

2002 to 2014 sediment cores collected by SCUBA divers from 17 sites in McMurdo Sound, Antarctica. Samples were analyzed for grainsize distribution, total organic carbon, and nitrogen content. The dataset was produced by the organization SCIOPS.

Use Cases

• Model relationships between sediment grainsize distribution and total organic carbon content across 17 Antarctic sites.
• Analyze temporal trends in carbon and nitrogen concentrations in marine sediments from 2002 to 2014.
• Correlate sediment properties like grainsize statistics with epifauna data from the related McMurdo epifauna dataset.
• Study spatial variability in sediment composition (carbon, nitrogen, grainsize) across McMurdo Sound sampling locations.

Strengths

• Data spans 13 consecutive years (2002-2014), providing a multi-year time series.
• Samples from 17 distinct geographic sites enable spatial analysis.
• Detailed methodological description for grainsize and carbon/nitrogen analysis ensures reproducibility.

Limitations

• Exact row count, sample size per site, and column names are unknown.
• Geographic coverage is limited to McMurdo Sound, Antarctica, limiting broader applicability.
• Data collection ended in 2014, representing conditions up to a decade old.
