The survey was undertaken to investigate the seabed geomorphology and sedimentary processes in the vicinity of Turnagain Island and to infer the possible effects (if any) on the distribution, abundance and survival of seagrasses. The Turnagain Island region was chosen because it is a known site of recent widespread seagrass dieback. The present survey is the first of two by Geoscience Australia to be carried out in 2004 and is part of a larger field-based program managed by the Reef CRC aimed at identifying and quantifying the principal physical and biological processes operating in Torres Strait. The impetus for the program is the threat of widespread seagrass dieback and its effects on local dugong and turtle populations and the implications for indigenous islander communities. {"type": "Polygon", "coordinates": [[[142.0, -10.0], [142.5, -10.0], [142.5, -9.5], [142.0, -9.5], [142.0, -10.0]]]} 142.0 142.5 -10.0 -9.5 AU-QLD Earth Sciences GA Publication Published_External Record bathymetry geomorphology marine marine survey resource management Download the Record (pdf) documentDigital Download the Record (pdf) PDF Unnamed resource documentDigital HTML
