2800 km of bathymetric and seismic reflection profiles covering approximately 110,000 km² of the Argo Abyssal Plain in the eastern Indian Ocean. The data, likely from the Australian Ocean Data Network, reveals the tectonic and sedimentary history from the Late Jurassic to the present. It identifies structural features like the Wombat Graben and Joey Rise, and correlates sediment sequences with ODP Site 765 and DSDP Site 261.
Use Cases
- Modeling tectonic subsidence and crustal cooling based on identified structural features and sediment thicknesses.
- Analyzing sediment deposition trends controlled by basement structure using isopach maps.
- Correlating seismic sequences with lithology from known drill sites (ODP Site 765, DSDP Site 261).
- Investigating the impact of the Sunda Trench fore-bulge on uplift in the northern and eastern parts of the plain.
- Mapping the geometry and sediment fill of newly identified grabens (Joey, Wombat, Kivi).
Strengths
- Approximately 2800 km of analyzed bathymetric and seismic reflection profiles.
- Coverage spans about 110,000 km² of the Argo Abyssal Plain.
- Identifies specific sediment thicknesses, such as 1.2 km in the central basin and up to 1 km in the Joey Graben.
- Correlates sediment sequences with lithology from two established ocean drilling sites.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data formats are PDF and HTML, which may require conversion for quantitative analysis.
