Presentation Studies of seafloor geomorphology across various spatial scales in Antarctica

Description
At Geoscience Australia, we use bathymetry data and seafloor geomorphology information across a range of spatial scales. I will present examples of where this information has been applied to continental, regional and local-scale studies in Antarctica. Bathymetry data, particularly high-resolution data from multibeam echosounders, provide insights into seafloor characteristics and a means to map large areas of the seafloor and delineate them into geomorphological regions. Geomorphic maps present an integrated view of the seafloor that can be used to understand the origin of the seafloor features, the action of physical processes that modify them, and how these processes affect the modern seafloor environment. These maps are valuable tools for improving our understanding of ecosystem patterns and processes governing benthic biodiversity, promoting scientifically-sound management decisions and establishing environmental baselines. This information is also useful to a broad range of scientific end-users as observations of ocean currents, temperature, biological production and diversity, and chemical and physical properties invariably require a description of the seafloor’s shape in order to be fully understood.
