Arctic : of, relating to, or suitable for use at the north pole or the region near it arctic waters arctic animals arctic clothing (often capitalized) — Webster
Arctic is a polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Alaska (United States), Canada, Finland, Greenland (Denmark), Iceland, Norway, Russia and Sweden. Land within the Arctic region has seasonally varying snow and ice cover, with predominantly treeless permafrost-containing tundra. Arctic seas contain seasonal sea ice in many places.
The Arctic region is a unique area among Earth’s ecosystems. For example, the cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. In recent years, Arctic sea ice decline has been caused by global warming. Life in the Arctic includes organisms living in the ice, zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies. Arctic land is bordered by the subarctic. — Wikipedia

- Thank You, Deeplyby John Thompson on September 15, 2017 at 10:15 am
An important message for the Arctic Deeply community.
- Building a Home for Labrador’s Inuit Cultural...by Susan Nerberg on September 15, 2017 at 5:41 am
Construction is wrapping up on the Illusuak Cultural Centre, a striking wooden structure being built on the shores of the North Atlantic in Nain, Canada, to celebrate the region’s Inuit heritage.
- Uncovering Clues About the Arctic’s Past...by Megan Stewart on September 14, 2017 at 5:54 am
Arctic cruise passengers are being enlisted to help analyze logbooks kept by whalers nearly two centuries ago in an effort to better understand how sea ice in the region has shrunk.
- Proposed Port and Road in Canada’s Central...by Gloria Dickie on September 13, 2017 at 4:25 am
Nunavut is pushing for federal cash to help advance a mining project that would bring badly needed jobs to the territory’s northwest. But critics – including territorial government biologists – worry about the impact on a nearby barren-ground caribou herd.
- Canada’s New Arctic Research Facility Prepares...by Brian Owens on September 12, 2017 at 9:12 am
The Canadian High Arctic Research Station in Cambridge Bay will serve as a base for scientists studying everything from the region’s changing cryosphere to how to best deploy renewable energy projects in northern communities.

- Where's the sea ice? 3 reasons the Arctic freeze...on October 28, 2020 at 2:01 pm
With the setting of the sun and the onset of polar darkness, the Arctic Ocean would normally be crusted with sea ice along the Siberian coast by now. But this year, the water is still open.
- Coastal Greenland reshaped as Greenland ice sheet...on October 27, 2020 at 8:31 pm
Ice loss from the Greenland Ice Sheet has accelerated significantly over the past two decades, transforming the shape of the ice sheet edge and therefore coastal Greenland, according to scientific research led by Twila Moon, deputy lead scientist of the National Snow and Ice Data Center. These changes to the ice sheet could have far-reaching impacts on ecosystems and communities, as the flow of water under the ice sheet as well as nutrient and sediment flow are altered. Results of the research […]
- Global 'BiteMap' reveals how marine food webs may...on October 26, 2020 at 7:00 pm
Where are small marine animals most vulnerable to getting eaten? The answer has big consequences for coastal ecosystems, where most of the world's fishing takes place, since predators can radically change underwater communities. In a new study published in Proceedings of the National Academy of Sciences Oct. 26, an international team of scientists sketched the first global "BiteMap" showing where the ocean's mid-sized predators are most active. By fishing with dried squid baits called "squid […]
- The uncertain future of the oceanson October 26, 2020 at 2:49 pm
The ocean plays a key role in the current climate change, as it absorbs a considerable part of the atmospheric carbon dioxide emitted by mankind. On the one hand, this slows down the heating of the climate, and on the other hand, the dissolution of CO2 in seawater leads to acidification of the oceans. This has far-reaching consequences for many marine organisms and thus also for the oceanic carbon cycle. One of the most important mechanisms in this cycle, is called the biological carbon pump. […]
- Coastal permafrost more susceptible to climate...on October 23, 2020 at 6:52 pm
If you flew from the sea towards the land in the north slope of Alaska, you would cross from the water, over a narrow beach, and then to the tundra. From the air, that tundra would look like a landscape of room-sized polygonal shapes. Those shapes are the surface manifestations of the ice in the frozen ground below, a solidified earth known as permafrost.
