High-resolution ocean modelling of the South Georgia and South Orkney Islands regions
South Orkney Islands is highly productive, with a history of commercial exploitation. Many of the key ... oceanographic and ecological processes that determine the structure and functioning of this ecosystem operate ... over small scales of <10 km. Historically, these fine spatial scales have been poorly represented in ... numerical models. Here we describe the development of two regional ocean models that will be used to examine ...
