Toxicity of Antarctic Diesel in Sediment to Heart Urchins

A 10-day exposure bioassay measured the toxicity of dispersed and undispersed Special Antarctic Blend diesel in marine sediment to the temperate heart urchin Echinocardium cordatum. The dataset includes daily observations of burial status and survival, along with environmental parameters like salinity, dissolved oxygen, pH, and temperature. Data was collected under the umbrella project ASAC_2201 by the organization AU_AADC.

Use Cases

• Modeling the acute toxicity of diesel contaminants in sediment based on urchin burial and survival data.
• Comparing the effects of dispersed versus undispersed fuel on marine invertebrates.
• Analyzing correlations between environmental parameters (salinity, pH, temperature) and organismal stress responses.
• Training predictive models for ecological risk assessment of Antarctic fuel spills.

Strengths

• Experimental design includes a controlled 10-day exposure period with daily observations.
• Data includes key environmental covariates: salinity, dissolved oxygen, pH, and temperature.
• Directly compares two contamination scenarios: dispersed and undispersed diesel.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
