A number of substrates deployed in this series of experiments were lost due to entrainment in ice. The quality of the attached datasets is also poor, in that they are poorly explained. The data were archived by the contributing scientist before she left the Australian Antarctic Division. Attempts by the AAD to obtain further details about the dataset have not proven successful. Metadata record for data from ASAC Project 1229 See the link below for public details on this project. --- Public Summary from Project --- This project will develop a method to monitor human impacts in the shallow marine environment of Antarctica. Artificial substratum units, placed at polluted and unpolluted sites, will be recovered after a specific time interval and resident animal communities will be compared to identify the type and magnitude of impacts. Data are community abundance data from artificial substrate units comprised of three nylon mesh pot scourers. Taxa are identified to morphospecies. Substrates were deployed in nearshore waters of Casey Station. Standard deployment was 1 year at 14m depth. Four main sites were used - Brown Bay, Newcombe Bay, O'Brien Bay and Browning Peninsula. Brown Bay is a known contaminated site. Experiments were designed to investigate natural variation on spatial and temporal scales, habitat area and potential impacts of a contaminated site, Brown Bay.
