PHYSICAL CONTROLS ON CORAL COMMUNITIES ON THE GEORGE V LAND SLOPE: SOME WORKING HYPOTHESES
their likely distribution. The CEAMARC survey of 2007/2008 found these communities at sites on the upper ... slope in depths of 570 – 950 m. Based on these results we propose some working hypotheses to explain ... their distribution. Icebergs scour to 500 m in this region and the lack of such disturbance is probably ... a factor allowing growth of rich benthic ecosystems. In addition, the richest communities are found ...
