Southern Surveyor SS2009_V06: High-Resolution Seafloor Bathymetry and Backscatter

271 raw data files totalling 3.95 GB of multibeam echosounder data collected during the Southern Surveyor voyage SS2009_V06 in October/November 2009. The Simrad EM300 system acquired high-resolution seafloor bathymetry and backscatter information on a transit from Sydney to the Barcoo and Taupo seamounts. Data are stored in Simrad *.all raw format at CMAR and Geoscience Australia, with additional details in the voyage's cruise and data processing reports.

Use Cases

• Map seafloor bathymetry based on high-resolution multibeam echosounder data.
• Analyze seafloor backscatter intensity for substrate characterization.
• Study the morphology of the Barcoo and Taupo seamounts using the collected survey data.
• Process raw Simrad *.all format files for custom bathymetric product generation.

Strengths

• 271 raw data files provide a substantial volume of primary survey data.
• Data totals 3.95 GB, indicating a detailed survey record.
• High-resolution seafloor bathymetry and backscatter information were acquired.
• Specific voyage path (Sydney to Barcoo and Taupo seamounts) and time period (Oct/Nov 2009) are documented.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness should be verified; the last metadata update is dated 2026-06-04.
• Data may reflect geographic and temporal bias inherent to the specific 2009 survey voyage.
