BMRG06MV: Bathymetry Survey from Fremantle to Port Hedland, 1996

Bathymetry data was collected from 22 February to 13 April 1996 during a transit from Fremantle to Port Hedland, Australia. The dataset consists of 32-bit geotiffs with a resolution between 128 and 210 meters, processed from SeaBeam 2000 sonar data. The survey was conducted by Bishop Museum and UC San Diego aboard the R/V Melville, with data processed using CARIS HIPS and SIPS software.

Use Cases

• Modeling seafloor topography based on the 128-210 meter resolution bathymetry grids.
• Analyzing tectonic features along the Southeast Indian Ridge based on the survey's geographic coverage.
• Creating base maps for marine research based on the processed SeaBeam sonar data.
• Studying the geological transition between Fremantle and Port Hedland based on the transit path.

Strengths

• Data has a defined spatial resolution between 128 and 210 meters.
• Survey has a precise temporal coverage from 22 February to 13 April 1996.
• Original data collection involved specific institutions (Bishop Museum, UC San Diego) and equipment (SeaBeam 2000, R/V Melville).

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.
• Row count is unknown, which may limit suitability assessment.
