Dataset: Assessment of the effects of the 2004 coral bleaching event at Lihou Reef National Nature Reserve (Coral Sea) using towed video (Towvid)


Reefs in the Lihou Reef National Nature Reserve (NNR) were surveyed between 8-13 October 2004 in order to assess the effects of significant coral bleaching, which was observed during previous surveys in March 2004.

A series of six video tows were conducted at depths between 45m and 60m, in the lagoon area of Lihou Reef NNR and also to the north of Anne Cay. A computer-based application, allowing keyboard classification was used to analyse the video tapes. Habitats were classified based on the substrata (3 categories) and overlying epibenthos (6 categories) viewed on the tapes.
