Thick pack ice and snow cover almost all of the ocean in winter and most of it in summer. Explore the Arctic Ocean, Earth’s northernmost body of water, and its vital role as a biome in WWF report, Nature’s Technicians. Despite harsh weather and ice, the Arctic Ocean teems with life. Its extent in the Arctic has a clear seasonal cycle, with maximum ice extent in March, when it covers the entire Arctic Ocean and large parts of the Bering and Barents Seas and may extend all the way south to Iceland. Jul 20, 2016 · The hydrologic (water) and carbon cycles in the changing Arctic are highly complex and require an understanding of the biological, chemical, and physical processes that drive these cycles. This annual cycle of extremes has shaped the diversity of plants and animals and how they interact with their environment in the Arctic Ocean. The most northern parts of Eurasia and North America are around the Arctic Ocean. The fact that the Arctic ocean is largely covered in ice and relatively isolated from most of the other oceans makes this ocean incredibly unique. With major changes affecting the very environment they live in, especially the reduction in sea ice, the way these organisms interact with their environment is also changing. The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; [5] its salinity is the lowest on average of the five major oceans, due to low evaporation, heavy fresh water inflow from rivers and streams, and limited connection and outflow to surrounding oceanic waters with higher salinities. Such changes are likely to affect, and may alter, the Arctic food web and ecosystem. With each day longer than the previous one, light begins to penetrate through the thick cover of snow and ice to the under- surface of the ice, where ice algae begin to grow, like mold on a damp ceiling. . Sep 15, 2004 · Scientists have documented dramatic shifts in Arctic ice cover, water temperature in the Arctic Ocean, and the atmosphere above it—all potentially due to the effects of a warming climate. Organisms in the Arctic must cope with Earth’s harshest conditions, in terms of light and temperature. tngi znu xpl lkjqgwbo gdhp dknhth cgglzd hkdma xulhzhde vfwx
