A survey of macrobenthic assemblages in soft-sediments was conducted at Casey Station, East Antarctica. Samples were taken along four transects in Brown Bay, up to 300 meters long, along a pollution gradient from an abandoned waste tip. The dataset includes 62 samples for fauna and 62 for heavy metal and hydrocarbon analysis, collected by divers using hand-held corers in 1999.
Use Cases
- Modeling pollution gradients based on distance from a waste tip.
- Analyzing correlations between heavy metal concentrations and benthic species presence.
- Studying the impact of hydrocarbon contamination on diatom communities.
- Mapping benthic assemblage distribution along spatial transects.
Strengths
- 62 paired samples for fauna and contaminant analysis provide matched data points.
- Samples taken at precise distances (10m to 300m) along four transects define a clear spatial gradient.
- Multiple sediment properties were examined, including grain size and benthic diatoms.
Limitations
- Last updated 1999-01-18 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.
