Argo Abyssal Plain Sediment and Geophysical Survey Data

Geoscience Australia Data collected geophysical traverses and sediment cores from the Argo Abyssal Plain in the northeast Indian Ocean. The data includes isopach maps of sediment thickness, evidence of diapirs, and a diverse group of core samples such as siliceous clays, calcareous oozes, and manganese nodules. The dataset was last updated on 2026-05-14.

Use Cases

• Model sediment thickness distribution based on isopach maps derived from seismic profiles.
• Analyze the composition and origin of seabed diapirs indicated in the survey data.
• Study carbonate compensation depth (CCD) effects using calcareous and siliceous core samples.
• Investigate volcanic basement structures based on recovered hyaloclastites and basalt samples.

Strengths

• Includes a diverse collection of physical sediment cores from multiple site types, such as below and above the CCD.
• Covers a specific geographic region with geophysical traverses providing subsurface structural data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description indicates it was not possible to determine if probable diapirs are salt or mud-cored.
