10 cze 2024 · Color-coded map of the daily sea ice concentration in the Northern Hemisphere for the indicated recent date along with the contours of the 15% edge during the years with the least extent of ice (in red) and the greatest extent of ice (in orange) during the period from November 1978 to the present.
Animals and plants: Many species of organisms live around the edges and in and under the sea ice. Nutrients and sunlight form the basis for the production of enormous amounts of algae and phytoplankton, which are the bottom level in the marine food chain in the Arctic.
These graphs show estimates for the ice-free season as a function of global warming for southern Hudson Bay (top) and western Hudson Bay (bottom). Two estimates are provided based on different methods to bias-adjust the climate model data to match the observations during the satellite data record.
This article discusses the types of plants found in the Arctic and Antarctic as well as the adaptations that enable their survival in the polar regions' harsh conditions.
Sea ice data is updated daily, with a one-day lag. The orange line in extent and concentration images (left and middle) and the gray line in the time series (right) indicate 1981 to 2010 average extent for the day shown. The graph also includes lines for selected earlier years, for comparison.
22 lis 2019 · Polar bears survive with their thick oily fur coats and layers of body fat, keeping them insulated. They are the largest bears in the world and can easily kill prey with their sharp claws. They travel all over the Arctic in search of food.
Watch animals of the ice run, swim, slide, waddle, and fly. Polar bears, penguins, seals, fish, krill and birds, all live on or under the ice. How they survive in the harsh extremes of the polar regions is amazing.
