Description
Fifteen geotiff files contain processed bathymetry data from a 47-day survey conducted by RV Falkor from September 30 to November 17, 2020. The survey mapped submarine canyons, drowned reefs, and an underwater landslide in the Cape York Peninsula region and Coral Sea Marine Park using Kongsberg EM302 multibeam sonar. This dataset is published with the permission of Geoscience Australia.
Use Cases
Mapping submarine canyon distribution based on bathymetry data.
Analyzing the extent and nature of underwater landslide debris fields.
Identifying drowned reef structures and other significant seabed features.
Filling data gaps between existing LIDAR and multibeam surveys for slope mapping.
Strengths
Data covers a frontier marine region with previously limited multibeam coverage.
Survey spanned 47 days and targeted specific geological objectives.
Includes backscatter and water column data alongside bathymetry.
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.
