WEST10MV: Bathymetry Survey of the Southeast Indian Ridge, 1995

Bathymetry data was collected by Oregon State University aboard the R/V Melville from 29 January to 12 March 1995 using a SeaBeam 2000 sonar system. The dataset contains 8-210m resolution, 32-bit geotiffs processed with CARIS HIPS and SIPS software from a transit between Fremantle, the Southeast Indian Ridge, and Hobart. Original scientists David Christie and the Marine Geoscience Data System should be acknowledged.

Use Cases

• Modeling seafloor topography based on the bathymetric geotiffs.
• Analyzing tectonic features of the Southeast Indian Ridge based on the survey data.
• Creating base maps for oceanographic research based on the georeferenced imagery.
• Studying the resolution and accuracy of sonar-derived bathymetry based on the 8-210m resolution data.

Strengths

• Data collection occurred over a defined period from 29 January to 12 March 1995.
• Geotiffs have a specified resolution range of 8 to 210 meters.
• Processing methodology is described, using CARIS HIPS and SIPS software.
• Clear attribution requirements are stated for the original scientists and data system.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
