Torres Strait Seabed Survey for Seagrass Dieback Analysis, 2004

Central Torres Strait seabed geomorphology and sedimentary processes were investigated by Geoscience Australia survey 266 in 2004. The survey focused on the Turnagain Island region, a site of recent widespread seagrass dieback, to infer effects on seagrass distribution and survival. This work was part of a larger field-based program managed by the Reef CRC to identify physical and biological processes in the strait.

Use Cases

• Modeling seabed geomorphology's impact on seagrass distribution based on survey data.
• Investigating sedimentary processes as a potential cause for seagrass dieback mentioned in the description.
• Assessing threats to dugong and turtle populations linked to seagrass habitat loss.
• Supporting indigenous community resource management with physical ecosystem data.

Strengths

• Data originates from a targeted 2004 Geoscience Australia survey (survey 266) to a known ecological site.
• Report is part of a larger, managed field program (Reef CRC) aimed at quantifying principal processes.
• Focuses on a specific, ecologically significant region (Turnagain Island, central Torres Strait).

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 as a PDF/HTML report; structured tabular data may require extraction.
