Cesium-137 and Strontium-90 Concentrations in Antarctic Soils and Vegetation

South Shetland Islands soil profiles and vegetation samples were analyzed for radioactive isotopes. The dataset includes measurements from 21 sampling sites with similar annual precipitation, with soil samples collected up to 25 cm deep. Data was processed for gamma and chemical separation by the organization SCIOPS, with a last update recorded in 1995.

Use Cases

• Modeling vertical distribution of Cs-137 in soil profiles based on the described 25 cm sampling depth.
• Comparing radionuclide concentrations in soils, moss, and lichen as mentioned in the title.
• Analyzing the relationship between edaphic parameters and radionuclide retention based on the described soil analysis.
• Assessing environmental contamination in Antarctic regions based on the specific geographic focus on the South Shetland Islands.

Strengths

• Data is collected from 21 distinct sampling locations, providing spatial coverage.
• Soil profiles are sampled to a depth of 25 cm, allowing for vertical distribution analysis.
• Includes analysis of multiple sample types: soils, moss, and lichen.

Limitations

• Last updated 1995-01-11 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
