Merri Marine Sanctuary Seafloor Bathymetry Survey from 2014

Four days of high-resolution bathymetry data collected in 2014 by Deakin University for Parks Victoria. The survey used a Kongsberg EM2040c multibeam echosounder onboard the Motor Vessel Yolla to map the seafloor inside and outside the Merri Marine Sanctuary. These data were intended to help associate southern rock lobster populations with specific seafloor habitats.

Use Cases

• Modeling benthic habitat types based on seafloor depth and structure data.
• Analyzing the association of southern rock lobster with specific seafloor features mentioned in the description.
• Creating high-resolution base maps for marine protected area management and research.

Strengths

• Data collected over four specific days in March and April 2014, providing a temporal snapshot.
• Acquired using a Kongsberg EM2040c multibeam echosounder, suggesting high-resolution seafloor mapping.

Limitations

• Row count, column definitions, and file size are unknown, limiting suitability assessment.
• Description metadata is limited; actual data quality and format require manual inspection after download.
