WEST10MV: Bathymetry Survey of the Southeast Indian Ridge, 1995

The WEST10MV bathymetry survey was acquired from 29 January to 12 March 1995 by Oregon State University onboard the RV Melville. This dataset contains 8-210 meter resolution geotiffs of the seafloor produced from processed SeaBeam 2000 sonar data. The data was collected during a transit from Fremantle to the Southeast Indian Ridge to Hobart.

Use Cases

• Modeling seafloor topography based on multibeam sonar bathymetry data.
• Analyzing geological features of the Southeast Indian Ridge based on high-resolution depth measurements.
• Creating base maps for marine research expeditions based on the survey's spatial coverage.

Strengths

• Data acquisition details are explicitly documented, including the vessel (RV Melville), sonar system (SeaBeam 2000), and processing software (CARIS HIPS and SIPS).
• The specific survey period (29 Jan - 12 Mar 1995) and transit route (Fremantle to Southeast Indian Ridge to Hobart) are provided.
• The dataset contains 32-bit geotiffs with resolutions ranging from 8 to 210 meters.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total file size are unknown, which may limit suitability assessment.
