Maintenance and Update Frequency: asNeeded Statement: Data source: field surveys camera systems data files (dvid) used to calculate camera position, link data to video frames via tape-timecode still images renamed using UTC time stamp, linked to video and camera systems files via time stamp. Annotation: (1) Broad-scale video scoring of substrate and habitat structuring biota in VARS using CATAMI classification codes. (2) Fine-scale photo-scoring, counts of biota individuals identified based on CATAMI classification in VARS. Densities calculations based on image FoV determined based on in-water calibrations using lens characteristic and sensor-based pitch, roll and altitude of the camera system. The data are added to common image annotation table in Oracle (BHIMAGE). Credit GAB DMP: Chevron Energy Technology Pty, CSIRO Credit Sub-project 4.2.2.

A key objective for which is to characterise the composition, abundance and distributions of benthic fauna (seabed animals) associated with volcanic seamounts, canyon and seep zone habitats in in ~1000-5000 m depth, within and adjacent to the Chevron lease areas in the GAB. Towed camera transecs were taken at 6 potential seep, 5 volcanic seamount. This metadata record refers to the image data collected during the surveys. The 'on-botom' videos and still images have been archived as described in MarLIN record 'Benthic Habitats Video Image Archive' (UUID: ...
