Submerged Coral Reefs in the Gulf of Carpentaria, Australia

Australian Ocean Data Network reports the discovery of three submerged, living patch coral reefs covering 80 km² in the southern Gulf of Carpentaria. The reefs were identified using multibeam swath sonar, seabed sampling, and underwater video, with their upper surfaces at a mean depth of 28.6±0.5 meters. Their existence suggests a past phase of reef growth under different climate and sea level conditions, and they may serve as a refuge from coral bleaching.

Use Cases

• Modeling past coral reef distribution based on submerged reef locations and depths mentioned in the description
• Assessing potential coral refugia from thermal stress based on the concept of deeper, submerged reefs
• Mapping submerged geological features in tropical regions using bathymetric survey methods described
• Studying late Quaternary sea-level and climate changes inferred from the reef's existence and depth

Strengths

• Describes a specific discovery of three reefs covering 80 km²
• Provides precise mean depth measurement of 28.6±0.5 meters
• Documents the survey methodology (multibeam sonar, sampling, video)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is presented in HTML format, which may require extraction for analysis
