Abstract

In 2007, we mapped the spectacular submarine landscape on the Great Barrier Reef margin. This included a completely new coldwater coral habitat in the depths of the Queensland Trough. Coldwater coral habitats are important globally as hotspots of biodiversity on the deep seabed, but their ecology is poorly understood and the corals are vulnerable to damage. The project will study the origins and biodiversity of the coldwater corals, and to understand the role of the landscape in defining the habitat boundaries. 14C AMS ages of the biogenic and non-biogenic carbonate samples will be a major contribution to the overall aims of the project.
