New techniques for observing the Arctic Ocean circulation and its freshwater budget
After a brief recap of a representative freshwater budget for the Arctic and of how climate models expect the freshwater delivery to the Arctic to change, this talk concentrates on five areas where our understanding of the freshwater budget and the processes important to it appear to have been materially advanced during recent years, including but not necessarily restricted to the IPY. These include: (1) new ideas on the behaviour of the greatest oceanic freshwater reservoir on Earth (Proshutinsky, Toole); (2) new intricate ideas on ocean-climate feedback processes along the Arctic margin of the Beaufort and Chukchi seas as the land-fast ice thins and breaks free (Shimada); (3) new ice-thickness techniques in support of sea ice prediction (Laxon/Giles, Wadhams, Gascard); (4) a new and practical approach to monitoring the freshwater flux through the Canadian Arctic Archipelago by combining observations with models (Prinsenberg, Peterson); and (5) new direct observations of the freshwater flux passing south through the Fram Strait (de Steur et al., Rabe et al.). Such a diverse set of examples serves to illustrate the broad front over which progress is needed -- and is being made -- in developing our understanding of these processes, their changes, their feedbacks and their likely climatic impacts to the point where they can be of practical use to the development of climate models. Meanwhile, in many cases, we are still in the process of exploration.
