Sediments of the Argo Abyssal Plain and Adjacent Areas, Northeast Indian Ocean

Geophysical traverses and coring by the Atlantis II provide information on sedimentary and tectonic processes in the northeast Indian Ocean. The dataset includes seismic profiles used to create isopach maps and a diverse group of sediment cores from sites above and below the carbonate compensation depth. Data was contributed by the Australian Ocean Data Network and last updated in June 2026.

Use Cases

• Model sediment thickness distribution based on seismic profile isopach maps.
• Analyze sedimentary composition based on recovered cores of siliceous clays, calcareous oozes, and calcareous clays.
• Investigate tectonic features like diapirs and basaltic structures based on seismic and sample evidence.
• Study manganese nodule formation based on samples from abyssal sites.

Strengths

• Includes a diverse collection of sediment cores from distinct geological settings, such as below the CCD and from a fore-arc basin.
• Contains geophysical traverse data used to create isopach maps showing sediment thickness.
• Provides physical samples including manganese nodules and basalt, suggesting material for direct analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description metadata is limited; actual data quality requires manual inspection after download.
