Helen's Rock Bathymetry Survey from 2013

A 2013 bathymetry survey of Helen's Rock acquired on November 27 by Deakin University Marine Mapping lab. Data was collected from the Motor Vessel Yolla using a Kongsberg EM2040c multibeam echosounder. The dataset is hosted by the Australian Ocean Data Network.

Use Cases

• Model underwater terrain based on the bathymetric survey data.
• Analyze seabed composition and features around Helen's Rock.
• Support marine habitat mapping using the high-resolution depth information.
• Integrate with other marine datasets for regional oceanographic studies.

Strengths

• Data was collected using a Kongsberg EM2040c multibeam echosounder, suggesting high-resolution depth measurements.
• The acquisition date (2013-11-27) and platform (Motor Vessel Yolla) are explicitly documented.

Limitations

• The description explicitly states 'Not to be used for navigational purposes', indicating potential accuracy or completeness limitations.
• Column-level documentation and row count are unknown, limiting suitability assessment.
• Metadata completeness is limited; actual data quality requires manual inspection after download.
