AAS_4512_TEMPOCTDcamera_benthicID
All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).

Description
This dataset contains raw images and associated metadata from the CTD camera deployed during the TEMPO voyage. Most krill studies focus on the epipelagic zone (surface to ~250m), but recent observations indicate that they can also exist within the abyssal zone. As a part of the TEMPO voyage a deep sea camera mounted to the CTD rosette was used to observe krill at the ocean floor. As a result seafloor images were collected during every full depth CTD deployment during the voyage. Images were taken via a Canon HFG10 mounted on to frame of the rosette. The camera and lights were switched on 25 m above the seafloor during the CTD decent and captured a still image every 10 seconds. At this point the focus was set to infinity. The CTD was lowered to 3-5 m from the seabed, after 2 minutes the focus was adjusted to 1 m. For each CTD deployment the highest quality image/s have been uploaded here. Whilst the ship was as stationary as possible there was enough movement of the to capture different sections of the seabed with the roll of the ship and subsequent movement on the CTD cable.
This work was completed as part of AAS projects 4512 and 4556:
4512 - Ensuring sustainable management of the krill fishery in waters off the Australian Antarctic Territory
4556 - Shaping the future use of environmental DNA (eDNA) in Southern Ocean ecosystem monitoring
