Seagrass Community and Bedform Migration Surveys in Torres Strait, Australia

Repeat multibeam sonar surveys were conducted during monsoon and trade wind seasons near Turnagain Island to investigate the potential impact of migrating bedforms on episodic seagrass disappearance. The dataset covers two study areas representing sand bank and sand dune environments for comparison. It was published by the Australian Ocean Data Network and last updated on 2026-06-05.

Use Cases

• Modeling the relationship between dune-crest migration and seagrass loss based on seasonal survey data
• Comparing sediment mobility characteristics between sand bank and sand dune environments
• Analyzing seasonal patterns of bedform migration from multibeam sonar surveys

Strengths

• Data collection targeted two distinct environments (sand bank and sand dune) for comparative analysis
• Surveys were repeated across two distinct seasons (monsoon and trade wind)
• Measurement method is specified as repeat multibeam sonar surveys

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Description metadata is limited; actual data quality requires manual inspection after download
