| Summary: | No abstracts are to be cited without prior reference to the author. Arctic and Antarctic marine systems have in common high latitudes, large seasonal changes in light levels, cold air/ sea temperatures, and sea ice. In other ways they are strikingly different, including: geological structure; ice stability; and food webs. Both regions contain rapidly warming areas; reported climate impacts and future projections are dramatic. Effects of changing climate on oceanographic processes and food webs influence their fisheries in different ways. Life-history strategies of zooplankton (Antarctic krill and Calanus copepods in the Arctic) may affect future fisheries productivity. To explore potential future scenarios for each region; this paper: 1) considers characteristics (geographic, physical, biological) defining these ecosystems, and reviews impacts of climate change on key zooplankton; 2) summarizes existing fisheries; 3) synthesizes this information to envisage future scenarios; 4) considers implications for ... |
