The Argo Abyssal Plain in the eastern Indian Ocean is covered by about 2800 km of bathymetric and seismic reflection profiles, spanning an area of approximately 110,000 km². The data, hosted by the Australian Ocean Data Network, reveals the tectonic and sedimentary history from the Late Jurassic to the present. It identifies structural features like the Joey Graben and sediment sequences correlated with ODP and DSDP sites.
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 known lithology from ODP Site 765 and DSDP Site 261.
- Investigating the impact of the Sunda Trench fore-bulge on uplift in the northern and eastern parts of the plain.
Strengths
- Covers a significant geographic area of approximately 110,000 km².
- Includes about 2800 km of analyzed bathymetric and seismic reflection profiles.
- Provides specific sediment thickness measurements, such as 1.2 km in the central basin.
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 limited to HTML and PDF, which may require extraction for analysis.
