Merri Marine Sanctuary Bathymetry Survey from 2014

2014 bathymetry data collected over four days (March 10, 11, 30, and April 1) by Deakin University Marine Mapping lab. The survey was conducted onboard the Motor Vessel Yolla using a Kongsberg EM2040c sonar system. These data were gathered for a Parks Victoria project to map the seafloor inside and outside the Merri Marine Sanctuary to help associate southern rock lobster with seafloor habitats.

Use Cases

• Modeling southern rock lobster habitat preferences based on seafloor bathymetry.
• Creating high-resolution seafloor maps for marine protected area management.
• Analyzing the relationship between bathymetric features and marine species distribution.

Strengths

• Data collected with a specific, high-resolution Kongsberg EM2040c multibeam sonar system.
• Survey conducted over four dedicated days in 2014, providing a focused temporal snapshot.
• Explicitly collected for a defined Parks Victoria project linking species to habitat.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data is explicitly flagged as 'Not to be used for navigational purposes', indicating potential limitations for certain applications.
