In February/March 2004, surveys of benthic habitats and fish faunas were undertaken in deeper waters of the Commonwealth waters surrounding Lord Howe and Balls Pyramid rises. Towed video gear (Towvid) was deployed at 21 stations around Lord Howe Island and Balls Pyramid. Deployments were located on the north east shelf (3), north slope (1), south west slope (5), south east shelf (2), east shelf (1), east slope (1) and south east slope (1) and west shelf (1) of Lord Howe Island. Single deployments were also made on the north slope, north east slope, south shelf, east slope, west shelf and the west slope of Balls Pyramid. A computer-based application, allowing keyboard classification was used to analyse the video tapes. Habitats were classified based on the substrata (9 categories), overlying epibenthos (10 categories) and individual organisms (2 categories) viewed on the tapes. This preliminary, rapid ecological assessment aimed to describe habitats and fish-habitat associations in deeper waters, below the depth limits of SCUBA observations. Towvid data was used to provide an overall quantitative perspective of the various habitats occurring in these waters.
