Hydrographic Surveys of Tasmanian Marine Parks, 2019

IMAS/CSIRO conducted multibeam mapping surveys in 2019 to map shelf waters of the Freycinet, Huon, and Tasman Fracture Marine Parks in Tasmania. The dataset includes raw multibeam outputs and post-processed data such as Caris files, xyz data, and geotiffs. This information was intended to increase knowledge of habitat distribution to underpin biological monitoring and assess natural versus anthropogenic pressures.

Use Cases

• Map seafloor topography and habitat distribution based on multibeam survey data.
• Support biological monitoring of key habitats within the Australian Marine Park network.
• Contrast ecological observations within marine parks with nearby fished locations to assess human impact.
• Create bathymetric models and visualizations from the post-processed xyz and geotiff data.

Strengths

• Includes both raw multibeam outputs and multiple post-processed formats (Caris files, xyz data, geotiffs).
• Surveys cover multiple designated marine parks (Freycinet, Huon, Tasman Fracture) and reference areas.
• A dedicated data report was produced by CSIRO, indicating documented processing.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total data size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific survey areas in eastern and southern Tasmania.
