Progress Code: completed Statement: The camera was being tested during this voyage and some of the video is of poor quality due to focus issues encountered during the first weeks of operation. Lighting was also generally inadequate although there are some useful images of the bottom obtained. Purpose This dataset was collected as part of a technology test of the camera system during a marine science voyage. It was not collected for scientific purposes, however, some of the data may be of scientific use. The RSV Aurora Australis V2 – Casey Resupply and Marine Science Voyage took place from 5 December 2014 to 25 January 2015. The voyage code is v2_201415020. The principal objective of the voyage was to undertake the Casey Resupply and then conduct marine science in the Dalton Polynya and near the Mertz Glacier. A downwards looking video camera system was fitted to the CTD and operated during most casts. The system was remotely controlled and typically operated only while the CTD was near the bottom although some videos show the complete descent through the water column. The video footage for each deployment was labelled as follows: VOYAGE_DATE_TIME_SITE.MTS Where: VOYAGE = v2_201415020 DATE = YYYY-MM-DD TIME = HHMMUTC (in 24 hr time) SITE = the CTD site name (e.g. SiteA5) Details on each site, including geographic coordinates and depth, are available in the Marine Data Voyage Report. The underway data from the voyage is available here: https://data.aad.gov.au/metadata/records/201415020
