Patagonian Gastropod Species and Sediment Data from Coastal Surveys

1753 gastropod specimens from 10 species and 5 families were collected from 37 sampling sites along the Patagonian coast. The dataset includes sediment samples analyzed for TBT concentration and granulometry, collected by SCIOPS between June 2006 and April 2008.

Use Cases

• Analyze species distribution patterns across 37 sampling sites using geospatial coordinates.
• Model the relationship between sediment TBT concentration levels and gastropod family or species presence.
• Compare gastropod counts and diversity between port areas and low marine traffic control zones.
• Study temporal changes in gastropod populations across the survey period from 2006 to 2008.

Strengths

• 1753 individual gastropod specimens recorded.
• Data spans 37 distinct sampling sites across a 14-degree latitude range (40°S to 54°S).
• Includes both biological (species, family) and chemical (TBT concentration) data points.

Limitations

• Sample size is limited to a single survey campaign from 2006-2008.
• Geographic scope is restricted to the Argentine Patagonian coast.
• Unknown row count and specific column schema limit immediate usability.
