Southeast Indian Ridge Bathymetry Survey from 1996

1996 bathymetry data from a transit between Fremantle and Port Hedland, Australia, was collected by scientists from Bishop Museum and the University of California San Diego aboard the R/V Melville. The dataset consists of 32-bit geotiff files with a resolution between 128 and 210 meters, processed from SeaBeam 2000 sonar data. It was produced using CARIS HIPS and SIPS software and is managed by the Australian Ocean Data Network.

Use Cases

• Analyzing seafloor depth and slope gradients from the 32-bit geotiff elevation data for geomorphological studies.
• Mapping underwater tectonic features and ridge structures using the 128-210m resolution bathymetric imagery.
• Modeling ocean circulation or habitat suitability by integrating the bathymetry data with other marine datasets.
• Calibrating modern sonar survey data by comparing against this 1996 SeaBeam 2000 baseline survey.

Strengths

• Bathymetric data spans a significant geographic transect from Fremantle to Port Hedland.
• Processed to a consistent 128-210 meter resolution providing detailed seafloor imagery.

Limitations

• Data is from a single survey in 1996 and may not reflect current seafloor conditions.
• Specific row counts, file sizes, and column definitions are unknown.
• The 32-bit geotiff format may require specialized GIS software for analysis.
