The Arctic is the northernmost region of Earth. Most scientists define the Arctic as the area within the Arctic Circle, a line of latitude about 66.5° north of the Equator. Within this circle are the Arctic ocean basin and the northern parts of Scandinavia, Russia, Canada, Greenland, and the U.S. state of Alaska The Arctic region, or the Arctic, is a geographic region spreading around the North Pole. There is no single correct definition of the region as the southern boundary varies. Key ways to define the Arctic: The Arctic Circle (66 ° 33'N) delimits the Arctic in terms of solar radiation . The MV Arctic Sea is a cargo ship formerly registered in Malta that was reported missing between late July and mid-August 2009 en route from Finland to Algeria, manned by a Russian crew and declared to be carrying a cargo of timber. Hijackers allegedly boarded the ship off the coast of Sweden on 24 July 2009 Arctic sea ice extent averaged for April 2021 was 13.84 million square kilometers (5.34 million square miles). This was 410,000 square kilometers (158,000 square miles) above the record low for the month set in 2019 and 850,000 square kilometers (328,000 square miles) below the 1981 to 2010 average. The average extent for the month ranks sixth.
Arctic sea ice reaches a maximum around March after the cold winter months and then shrinks to a minimum around September after the summer melt. However, these seasonal swings are not only linked to the changing seasons - it transpires that along with our warming climate, the temperature of adjacent ocean seawater is now also adding to the ice's vulnerability Arctic ice is melting as the climate crisis drives up temperatures, resulting in a vicious circle in which more dark water is exposed to the sun's heat, leading to even more heating of the planet

While the Arctic traditionally was characterized by cooperation and low tensions, that is changing. A report from the US Congressional Research Service (CRS) on the Arctic notes that although there is still important cooperation in the region, the Arctic is increasingly seen as an area for geopolitical competition amongst the US, China, and Russia The Arctic oceans are often not included in the global sea level estimation. This is partly due to seasonal changes in the sea-ice cover and insufficient satellite coverage The Arctic consists of land, internal waters, territorial seas, exclusive economic zones and international waters above the Arctic Circle. All land, internal waters, territorial seas and EEZs in the Arctic are under the jurisdiction of one of the eight Arctic coastal states: Canada, Denmark, Finland, Iceland, Norway, Russia, Sweden and the United States. International law regulates this area as with other portions of Earth. Under international law, the North Pole and the region of the Arctic Oc The Arctic is an ocean basin surrounded by land, with the sea ice corralled in the coldest, darkest part of the Northern Hemisphere. The Antarctic is a continent surrounded by ocean. Whereas Northern Hemisphere sea ice can extend from the North Pole to a latitude of 45°N (along the northeast coasts of Asia and North America), most of the ice is found above 70°N مميّزات SPSS. 1- سهل جداً في التعامل والاستخدام، ومناسب لجميع مستويات المستخدمين. 2- يمكن إجراء التحليل باستخدام القوائم دون الحاجة إلى كتابة الأوامر. 3- يمكنه التعامل مع جميع أنواع الملفات تقريباً. 4- يتفوّق في الإحصاء الوصفي، وتحليل الانحدار الأساسي، وتحليل التباين

Arctic sea ice is much more than just extent and area. Below you can see our graphic, which shows the sea ice concentration. It tells us what is the fraction of the sea ice in the ocean. We mostly have 90-100% concentration, but it nicely shows just how diverse and dynamic the polar icecap really is across its vast size Explore the shores and seas of an amazing Arctic island. RVR20-22 At the end of a long Arctic winter, spring is starting to awaken. The climate, however, still clings to the cold: snow-covered mountains, snow-swept shores, temperatures around -4° C (25°F). It's a good time to experience the last of winter scenery,.. Arctic High Seas. Even if all or most of the Arctic seabed belonged to one State or another's continental shelf, there will still be a portion of the central Arctic Ocean water column that is beyond the jurisdiction of any coastal States. This area is the Arctic high seas. Other States would have the right to freely navigate and exploit the. Arctic. The Arctic is the northernmost region of Earth. Most scientists define the Arctic as the area within the Arctic Circle, a line of latitude about 66.5° north of the Equator. Within this circle are the Arctic ocean basin and the northern parts of Scandinavia, Russia, Canada, Greenland, and the U.S. state of Alaska Climate Change Indicators: Arctic Sea Ice. This indicator tracks the extent, age, and melt season of sea ice in the Arctic Ocean. Figure 1. March and September Monthly Average Arctic Sea Ice Extent, 1979-2016. This figure shows Arctic sea ice extent for the months of September and March of each year from 1979 through 2016
Throughout 2020, the Arctic Ocean and surrounding seas endured several notable weather and climate events. In spring, a persistent heatwave over Siberia provoked the rapid melting of sea ice in the East Siberian and Laptev Seas. By the end of summer, Arctic Ocean ice cover melted back to the second-lowest minimum extent on record. In autumn, the annual freeze-up of sea ice got off to a late. Tue, 8 June 2021. AFP. Sea ice in the Arctic's coastal regions may be thinning up to twice as fast as previously thought, according to a new study, with worrying implications for climate change. The analysis, led by researchers at Britain's University College London (UCL), concluded that the ice in the coastal regions was thinning at a rate. Are Arctic Sea Ice Melts Causing Sea Levels to Rise? Recent NASA photos showed the opening of the Northwest Passage and that a third of the Arctic's sea ice has melted in recent decades Over the past 22 years, sea levels in the Arctic have risen an average of 2.2 millimeters per year. This is the conclusion of a Danish-German research team after evaluating 1.5 billion radar.

It is assumed that they have been in ice captivity since January due to an exceptionally thick and fast ice build-up, but specialists only spotted the animals in April..
Arctic sea ice is a key indicator of the state of global climate because of both its sensitivity to warming and its role in amplifying climate change. Accelerated melting of the perennial sea ice cover has occurred since the late 1990s, which is important to the pan-Arctic region, through effects on atmospheric and oceanic circulations, the Greenland ice sheet, snow cover, permafrost, and. Implications from Opening Arctic Sea Routes 8 Figure 3. Changes in February and September multi-model mean Arctic sea-ice concentration from climate models for a 'business as usual' (BaU) emissions scenario. The pink contour represents satellite observed sea-ice extent 1986-2005 (15 per cent sea-ice concentration) The diminishment of Arctic sea ice has led to increased human activities in the Arctic, and has heightened interest in, and concerns about, the region's future. The United States, by virtue of Alaska, is an Arctic country and has substantial interests in the region. The seven other Arctic
. The floe is a vast, thin crust of ice measuring about 2.5km by 3.5km (1.5 miles by 2.2. This voyage, only possible thanks to climate change, highlights just one impact of melting Arctic sea ice. As the ice melts further new opportunities will arise to fish, to drill for oil and gas. Researchers have now uncovered one of the mechanisms driving this catastrophe, identifying how 'heat bombs' of warm, salty water from the Pacific Ocean flow into the frigid Arctic Ocean, heating the ice above from underneath for months or even years. The rate of accelerating sea ice melt in the Arctic has been hard to predict accurately, in part because of all of the complex local feedbacks. Reinforcing this finding, last month Arctic sea ice reached its second-lowest extent in the 41-year satellite record. A walrus rests on an ice floe near Svalbard, Norway. A new study predicts that. Sea ice in the Arctic and Antarctic areas. Updated on 26 Feb. 2021. Japan Meteorological Agency. The sea ice extent in the Arctic Ocean has shown a long-term trend of decrease since 1979. The change in the annual minimum sea ice extent is particularly notable, with a yearly reduction equivalent to the area of Japan's northern island of Hokkaido
The Arctic sea ice cap is a large area of frozen seawater floating on top of the Arctic Ocean and its surrounding seas and straits. For polar bears, the sea ice is a crucial platform for life. They use the ice to travel long distances to new areas. They hunt for seals by finding their dens or sitting next to gaps in the ice, waiting for the. The Northern Sea Route is one of several Arctic shipping channels and lies within Russia's exclusive economic zone. Russia has invested heavily to develop the route, which allows ships to cut the. . 1. The Arctic is located at the northernmost part of our planet. Scientists usually define the Arctic as the area above the 'Arctic Circle' — an imaginary line that circles around the top of the globe. 2. The Arctic consists of the Arctic Ocean and parts of Canada, Russia, the USA, Greenland, Norway, Finland, Sweden and Iceland Research shows that up to 234 particles have been found concentrated into just one litre of melted Arctic sea ice. That's much higher than in the open ocean. Researchers explain that sea ice forms.
The extent of the sea ice is defined by areas that have an ice concentration of at least 15%, i.e. 15% of the surface is covered by ice. The grey band around the climatological mean value corresponds to plus/minus one standard deviation . The extent of the ice is based on satellite data and are from the Ocean and Sea Ice, Satellite Application. Sea ice is now declining at a rate of 12.85 percent per decade, 6 and according to the Intergovernmental Panel on Climate Change, temperatures are rising twice as fast in the Arctic as compared to the global average. 7 Parts of Alaska's coasts have eroded as far as 2,500 feet over the last 60 years as melting permafrost weakens soil, water. Arctic sea-ice struggles to build volume. There is likely to be about 10,500 cu km of Arctic sea-ice by the end of the week - a volume that would tie for the lowest on record for a November. It is.
By Hui Min NeoAgence France-PresseBERLIN — The tipping point for irreversible global warming may have already been triggered, the scientist who led the biggest-ever expedition to the Arctic warned on Tuesday.The disappearance of summer sea ice in the Arctic is one of the first landmines in this minefield, one of the tipping points that we set off first when we push warming too far, said.

Today, the International Agreement to Prevent Unregulated Fishing in the High Seas of the Central Arctic Ocean enters into force. The Agreement will prevent commercial fishing by the signatory states in the high seas of the Arctic Ocean for the next 16 years. A time period that will be used to further our understanding of an ecosystem that is emerging below a retreating sea ice cover
The Arctic Ocean, and sea ice . Most of the Arctic Ocean is over 1000 m deep and is continuously covered with ice whose thickness varies between 1-10 m. About one third of the Arctic Ocean is shallow, i.e. continental shelf. Over these shelf areas, ice is absent at least part of the year, but ice is found year-round over the deep ocean As Arctic sea ice continues to melt, Arctic waters are experiencing more and more ship traffic. Last September, the Arctic matched the record for the second lowest sea ice extent: only in 2012 was there less seasonal sea ice in the Arctic Ocean at the end of the summer season Early in the month of August, 2012, storms in the Arctic affected the motion of the sea ice north of Siberia and Alaska. This animation shows the motion of the winds over the Arctic in conjunction with seasonal melting of the Arctic sea ice from August 1 through September 13, 2012, when the NASA scientists determined that the sea ice reached its annual minimum extent Sea ice in the central Arctic is predominantly multi-year in nature, with mean and modal ice thickness remaining stable at around 3.2 m and 2.5 m, respectively (Fig. 4.4b). Richter-Menge and Farrell (2013) showed that sea ice in the Beaufort and Chukchi seas region is more seasonal in nature and is a mix of multiyear (~25%) and first-year ice. The Arctic Sea is a 5,000-ton cargo ship that was carrying timber worth approximately $1.6 million from Finland to Algeria. It left port July 23, and the next morning was reportedly boarded in.
The Arctic is an unusual ocean in that it is stratified - or layered - by salinity instead of temperature. Most oceans of the world have warmer, lighter water near the surface and colder, denser water below. In the Arctic, however, there is a surface layer that is cold but very fresh, influenced by river outflow and accelerating ice melt The Central Arctic Ocean is the world's smallest ocean and is surrounded by Eurasia and North America. As sea ice declines dramatically, many governments are eager to take advantage of the shipping routes and natural resources available in this vulnerable region. Read mor Sea ice in the coastal regions of the Arctic may be thinning up to twice as fast as previously thought, according to a new modelling study led by UCL researchers. Sea ice thickness is inferred by. The increasing accessibility of newly open Arctic shipping lanes and ports bring with them troubling geopolitical implications. Photo: NOAA The advent of climate change has brought about a number of different changes in the Arctic, including increased accessibility to Arctic ports as well as the opening of new Arctic shipping lanes
Melting Arctic sea ice has contributed considerably more to warming at the top of the world than previously predicted by climate models, according to a new analysis of 30 years of satellite. Arctic Ocean Map and Bathymetric Chart. The map above was produced by Brad Cole of Geology.com using data licensed from Map Resources. It illustrates the Arctic Ocean and bordering countries. It also shows the Arctic Circle and minimal extent of the summer sea ice cover. Within the last few years, a significant amount of interest has developed.

Russia's Arctic territory stretches along 24,140 kilometers of coastline along the Arctic Ocean and waters above the Arctic Circle from the Barents Sea in the west at the border to Norway to the Bering Sea and the Sea of Okhotsk in the far east. Russia's coastline accounts for 53 percent of the Arctic Ocean coastline and covers the Barents Sea, Kara Sea, Laptev Sea, and East Siberian Sea Arctic sea ice extent, September 2019. Note: The Arctic sea ice extent in Sep. 2019 was 4.32 million square kilometres. The magenta line shows the 1981-2010 average extent for that month. Source: National Snow and Ice Data Center, ' Falling up: Arctic seas ice news and analysis', 3 Oct. 2019 09.25.07. Melting Arctic sea ice has shrunk to a 29-year low, significantly below the minimum set in 2005, according to preliminary figures from the National Snow and Ice Data Center, part of the University of Colorado at Boulder. NASA scientists, who have been observing the declining Arctic sea ice cover since the earliest measurements in 1979. The sea ice cover in the Southern Ocean surrounding Antarctica has been relatively stable, while Arctic sea ice has been declining rapidly over the past decade. River discharge is a key factor contributing to the high sensitivity of Arctic sea ice to climate change, said Nghiem The symbol of the Arctic is often the polar bear, the pole's cute yet fearsome top predator. These large marine mammals, who move easily between ice, water and land, are part of the diverse fauna of the Arctic Ocean.. What keeps this marine ecosystem going are organisms you can't see with the naked eye: microscopic phytoplankton and ice algae
The strong relationship between the summer SAT and September SIE was used to assess the onset of summer sea ice disappearance in the Arctic Ocean. According to the estimates made with a simple regression model, we can expect a seasonally ice-free Arctic Ocean as early as in the mid-2030s. An impact of the inflow of warm and salty Atlantic water. The maximum Arctic sea ice extent appears to have occurred on March 24, 2016, reaching an extent of 14.52 million square kilometers (5.607 million square miles). This is below the previous lowest maximum recorded in 2015 when it reached 14.54 million square kilometers (5.612 million square miles). Overall, there is a declining trend in the maximum extent of about 2.8 % per decade With most of its waters lying in the Arctic north polar region, the Arctic Ocean is the smallest and shallowest of the world's five oceans. Some scientists call the Arctic Ocean the North Mediterranean Sea or the Arctic Sea. Covering approximately 5,427,000 square miles, the body of water is approximately the size of Russia. Continents [ The melting of the sea ice has impacts far beyond the Arctic and its inhabitants. The melting of sea ice indirectly contributes to rising sea levels by lowering the sea surface's albedo
In some cases this is true. As a key part of Russia's economic growth in the Arctic, Moscow hopes the Northern Sea Route (NSR) will become one of the world's most important shipping lanes. Oil Drilling in Arctic Ocean: A Push into Uncharted Waters. As the U.S. and Russia take the first steps to drill for oil and gas in the Arctic Ocean, experts say the harsh climate, icy seas, and lack of infrastructure means a sizeable oil spill would be very difficult to clean up and could cause extensive environmental damage. Last October, an. In conclusion, the concept of the impact of Arctic sea ice on winter snowfall, as suggested by Liu et al. (), is basically consistent with the findings of Wu et al. published 2 y earlier.Wu et al. had already demonstrated that the autumn Arctic sea ice is an important predictor for northern continental-scale winter climate.Moreover, the reduced autumn sea ice is closely linked to the classic. Observed changes in Antarctic sea ice are small in comparison to the amount of sea ice that the Arctic has lost during the same period (see the Arctic Sea Ice indicator). Worldwide, the Earth has lost sea ice at an average rate of 13,500 square miles per year since 1979—equivalent to losing an area larger than the state of Maryland every year.

The recent resumption by the US Navy of a Barents Sea Patrol represents muscle-flexing on the part of Washington and its NATO allies unseen since the end of the Cold War. Three American destroyers and a British frigate, accompanied by a supply ship, ventured into the Arctic body of water last week. The reestablishment of the patrol is part of a.
The Arctic Ocean is absorbing more of the sun's energy in recent years as white, reflective sea ice melts and darker ocean waters are exposed. The increased darker surface area during the Arctic summer is responsible for a 5 percent increase in absorbed solar radiation since 2000 The Arctic is the poster child for the importance of the +1.5C target agreed at the 2015 UN Climate Conference in Paris (COP21). Simply put, if the world can maintain a ceiling of a +1.5C warmer world we can save the Arctic summer sea ice, and likely prevent some of the most serious climate impacts around the world
The Arctic is warming twice as fast as the lower latitudes, and scientists in report sea ice across the Nares Strait just collapsed two months earlier than normal On Feb. 25, Arctic sea ice extent stood at 5.61 million square miles across the Arctic, and featured below-average ice conditions everywhere except in the Labrador Sea and Davis Strait.
