Brief description
The seabed habitat, marine plant and sessile megabenthos cover of the 50,000 km² area of the Torres Strait Protected Zone and adjacent shelf seabed was observed by a 500 m transect of a Drop-Camera video system at 173 sites, representing a wide range of known physical environments, during one 1-month-long voyage on the James Cook University vessel James Kirby. Continuous underway coding during transects recorded cover of 9 substrata types, 26 biohabitat types, and occurrence of 12 faunal classes. Laboratory post-analysis of the video recorded more detail at ~30 random frames per transect, including: 20 substratum types, 92 biological types -- the dataset comprises ~28,000 site-by-type records. In addition, during most transects, digital still photographs were taken at 5-15 second intervals with strobes, and CTD data were recorded.Lineage

Statement: Site data were specified during the sampling design phase, date/time/position/depth of video recordings and observations were recorded from differential GPS and echo-sounder on vessel in the field. All videos were recorded on digital VTRs on vessel and real time observations in an on-vessel database. Video frames were subsequently quantified in more detail in the laboratory located at CSIRO (Brisbane) and data was entered into laboratory databases. All databases were collated and reconciled into a single database.
