The overall aim of this study was to understand the distribution, abundance and diversity of sea anemones from the Southern Ocean. Diversity and abundance of sea anemones in the Southern ocean is poorly studied with little information since their first discovery in the early 1900s. Understanding the species and the roles they play in the Southern Ocean can help assess their impact on other species and the impacts of environmental stress and disturbances on the Southern Ocean system. Sea anemone distribution and their relationship to their environment was surveyed with the use of a Remote Operated Vehicle (ROV) and photoquadrats from three Antarctic regions, Dumont d'Urville, Casey, and Davis Station. Through the use of an ROV at Dumont d'Urville Station, hundreds of metres of the benthic environment were covered in a short time frame allowing connections to be made between sea anemones and their environment at depths greater than can be reached diving. A positive association between sea anemones distribution ...
