East Antarctic seabed community data from a 47 cm sediment core beneath the Amery Ice Shelf. Fossil analysis reveals a succession of benthic organisms, including filter feeders and infauna, over the Holocene period from around 9600 years BP to the present. The dataset was published by Geoscience Australia Data and last updated in May 2026.
Use Cases
- Modeling benthic community succession based on the described faunal succession stages.
- Analyzing the relationship between ice shelf retreat and planktonic food supply advection mentioned in the description.
- Studying the impact of future ice shelf collapse on organic supply regimes and benthic communities.
- Reconstructing paleoenvironmental conditions in Prydz Bay based on fossil assemblages.
Strengths
- Data is derived from a 47 cm long sediment core providing a temporal sequence.
- The description details a clear faunal succession from mobile benthic organisms to filter feeders and infauna.
- The temporal context is specific, with events dated to around 9600 years BP.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified as the last update date is in the future (2026-05-14).
