Current dataset includes five sites including the ROV test site, a site to the south of Bird Island on the South Georgia shelf, the E2 and E9 segments of the East Scotia Ridge, and the Kemp Seamount.

This dataset includes high-definition video imagery, hydrographic and navigation data from the Isis remotely operated vehicle (ROV). These data were then used to perform a biometric and reproductive analysis on Kiwa tyleri sp. which also forms part of the dataset. Four hydrothermal vent and cold seep sites were sampled during thirty one ROV dives: south of Bird Island on the South Georgia shelf, the E2 and E9 segments of the East Scotia Ridge, and the Kemp Seamount. The dives were undertaken between 10th January 2010 and 12th February 2010 during the RRS James Cook research cruise JC042 (7th January - 24th February 2010). The Isis ROV was equipped with a high-definition video camera, a CTD package, an Ultra Short Baseline navigation system and a suction sampler. The data were produced as part of the NERC Consortium Grant project Chemosynthetic Ecosystems in the Southern Ocean (ChEsSo), which funded a total of four cruises (JR224, JC042, JC055 and JC080). The dataset contributed to the project aims to search for, identify and intensively study hydrothermal vent and cold seep sites in the eastern Scotia Sea. The existing dataset was produced by scientists from the University of Southampton and technicians from the National Oceanography Centre. Additional data for these cruises may become available in the future. Please note that the access restrictions for video imagery, hydrographic and navigation data are currently unknown. The biometric and reproductive analysis data are unrestricted and accessible through the Published Data Library.
