Research was conducted aboard the RVIB Nathaniel B Palmer during NBP14-02 (29 January – 16 March 2014) across a >3000 km2 area. A ‘yoyo’ camera, with downward facing digital still and video cameras mounted within a tubular steel frame, was deployed on a coaxial cable to image the seafloor. Still images have been analysed for seafloor habitats. The Ocean Imaging Systems DSC 10000 digital still camera (10.2 megapixel, 20 mm, Nikon D-80 Camera) was contained within a titanium housing. Camera settings were: F-8, Focus 1.9 m, ASA-400. An Ocean Imaging Systems 3831 Strobe (200 W-S) was positioned 1 m from the camera at an angle of 26o from vertical. A Model 494 Bottom Contact Switch triggered the camera and strobe at 2.5 m above the seafloor, imaging ~ 4.8 m2 of seafloor. Imagery can be viewed and downloaded from the National Computing Infrastructure (NCI) data catalogue THREDDS: https://thredds.nci.org.au/thredds/catalog/fk1/NBP14_02_Sabrina_Shelf/catalog.html
