This record describes the photographic transect survey data collected as part of the Tasmanian Seamounts Study undertaken by CSIRO Division of Fisheries in January 1997. Ten photographic transects were made from the base to pinnacle of 4 out of 14 seamounts in the survey area, approx. 100 km to the south of Tasmania, using a Photosea 2000 stereoscopic deepsea camera system, in water depths ranging from 2180 m to 714 m. The transects were typically oriented N-S and E-W on each seamount, with 2 transects replicated. Between 67 and 150 photos were taken per transect, at a mean range between photos of 27 m, at heights of 1 to 4 m off the bottom. The photographs were later assessed for percent cover by a range of bottom types, and for numbers of recognisable organisms of particular types. In 2008/09 the slide images were scanned and re-assessed for fauna and sediment types for comparison with image data collected on voyages SS11 / 2006 and SS2/2007. The image annotations collected for this project have been added to the Oracle data base BHIMAGE and the associated videos and still images have been archived as described in MarLIN record 14436 'Benthic Habitats Video Image Archive'.
