NERP Marine Biodiversity Hub, Theme 1 - Tasman Fracture Commonwealth Marine Reserve Pilot Study - Autonomous Underwater Vehicle (AUV) Component
The Tasman Fracture CMR AUV survey was a pilot study undertaken in 2014/15 as part of the National Marine Biodiversity Hub's National monitoring, evaluation and reporting theme. The aim of this theme is to develop a bluepint for the sustained monitoring of the South-east Commonwealth Marine Reserve Network. The particular aim of the survey was to contribute to an inventory of the distribution and cover of epibenthic biota in the reserve using IMOS AUV 'Sirius'.
Data contained here represents a scored subset of the ~ 18,400 images collected at the Tasman Fracture CMR. Images were scored for proportion cover of visible macrobiota using 25 random points superimposed on each image. Taxon were biologically classified using UTAS morphospecies classification scheme, which can be mapped back to CATAMI ( http://catami.org/).

- Statement
- Seabed imagery was collected with a modified Seabed class AUV, the IMOS AUV “Sirius”. The AUV is equipped with stereo camera pair and strobes, and its’ location calculated using a Doppler Velocity Log including a compass with integrated roll and pitch sensors, Ultra Short Baseline Acoustic Positioning System (USBL), and a forward-looking obstacle avoidance sonar. Seabed images were collected with a synchronized pair of high-sensitivity 12 bit, 1.4 megapixel cameras (AVT Prosilica GC1380 and GC1380C; one monochrome and one color). The two AUV missions were targeted at selected reefs that were observed in the multibeam sonar data collected in this region. The two missions are located inside the CMR directly west of the Mewstone. Each AUV transect was pre-programmed so that the AUV tracked the seabed at an altitude of 2 m at a cruising speed of 0.5 ms-1, resulting in an approximate width of the field of view of 1.5 - 2.5 m per image. All surveys were conducted during daylight hours. Selected AUV Imagery was scored for proportion cover of taxon using 25 random points superimposed on the image in TransectMeasure (SeaGIS). For each superimposed point the underlying taxon was identified to morphospecies level using the UTAS morphospecies classification scheme (available upon request), which can be Collaborative and Annotation Tools for Analysis of Marine Imagery (CATAMI) classification scheme ((http://catami.org/).
