Arctic Sea Ice At Second-lowest Level Since 1979
2011-09-16 04:32:17

  The extent of Arctic Ocean sea ice fell to its second-lowest size since 1979, the U.S. National Snow and Ice Data Center (NSIDC) said on Thursday. According to preliminary findings, the annual sea ice minimum was reached on September 9, when the ice covered 1.67 million square miles, the center said in a statement. "Changing winds could still push ice flows together reducing ice extend further," the researchers said. A full analysis will be available early next month, when...

Image 1- Arctic Ice Closes In On Record Low

  A new record low could soon be set for ice in the Arctic. The past five years have seen the lowest extent of sea ice since satellite measurements began in the 1970s. Earth observing satellites make it possible to measure the amount of sea ice in inaccessible areas such as the Arctic. This year, the extent of Arctic sea ice is comparable to the record low set in 2007. According to scientists at the University of Bremen in Germany, sea ice extent in early September has...

Arctic Sea Ice Extent Hits Record Low

  The area covered by Arctic sea ice during the summer reached a new all-time low on Thursday, with the summer sea ice extent falling to 1.64 million square miles (4.24 million square kilometers), scientists from a German university reported on Friday. According to AFP reports on Saturday, the current level is approximately one-half a percent below the previous record low, which dates back to the first satellite observations in 1972. Researchers at the University of Bremen's...

  A new report from the European Space Agency (ESA) shows that sea ice in the Arctic Ocean has receded dramatically during this summer, opening up two new shipping lanes - the Canadian Northwest Passage and Russia´s Northern Sea Route. The summer of 2007 recorded the lowest amount of sea ice since satellite observations began in 1979. That season was hit with unusual weather; skies opened over the central Arctic Ocean and wind patterns pushed warm air into the region,...

  Denmark - along with Greenland and the Faroe Islands, part of the Kingdom of Denmark - is looking to put itself on a collision course with four other nations, the United States, Russia, Norway, and Canada. All five countries are trying to lay claim to the Arctic Seabed, including the area around the North Pole. The document, called the Joint Arctic Strategy for 2011-2020 of the Kingdom of Denmark, was signed by Danish Foreign Minister Lene Espersen, Prime Minister of the Faroe...

  You can´t get any “higher”: on 22 August 2011 at exactly 9.42 a.m. the research icebreaker Polarstern of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association reaches the North Pole. The aim of the current expedition is to document changes in the far north. Thus, the researchers on board are conducting an extensive investigation program in the water, ice and air at the northernmost point on the Earth. The little sea ice cover makes...

The U.S. Geological Survey (USGS) said Thursday that it would attempt to attach 35 satellite radio-tags to walruses on the northwestern coast of Alaska as part of an ongoing study into how the mammals are responding to reduced Arctic sea ice conditions during late summer and fall. The fast-melting Arctic sea ice seems to be pushing the walruses out onto land, with many moving near the area where oil leases have been sold, the agency said. "Sea ice is an important component in the life...

In three decades of recording Arctic Ocean sea ice, the National Oceanographic and Atmospheric Administration (NOAA) on Monday reported that in July 2011 the sea ice hit its lowest monthly recorded level. Sea ice in the Arctic covered an average 3 million square miles during July, the lowest measurement for that month since the NOAA started keeping such records in 1979. The July 2011 figure is 81,000 square miles smaller than 2007's July record low and about 22 percent below the average for...

The melting of Arctic sea ice may temporarily stabilize, and the ice may even expand, over the coming years, according to new research by scientists at the National Center for Atmospheric Research (NCAR). "As we learn more about climate variability, new and unexpected research results are coming to light," said Sarah Ruth, program director in the Division of Atmospheric and Geospace Sciences, which funds NCAR. "What's needed now are longer-term observations to better understand the effect of...

Ice and frozen ground at the North and South Poles are affected by climate change induced warming, but the consequences of thawing at each pole differ due to the geography and geology, according to a Penn State hydrologist. "The polar regions, particularly the Arctic, are warming faster than the rest of the world," Michael N. Gooseff, associate professor of civil and environmental engineering, told attendees today (Aug. 11) at the 96th annual meeting of the Ecological Society of America in...

The Arctic Ocean which is located in the Northern Hemisphere and mostly in the Arctic north polar region, is the shallowest and smallest of the world’s five major oceanic divisions. The International Hydrographic Organization recognizes it as an ocean, although, some oceanographers consider it as the Arctic Mediterranean Sea or simply, the Arctic Sea, classifying it a Mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be considered as the northernmost...

Continental arctic air mass is known for its very frigid and dry air. The most common place in the United States to find this air mass is in Alaska. However, in the coldest parts of the winter such as December and January along with early February it is not uncommon for this air mass to invade the Northern part of the United States. This air mass is responsible for bringing with it temps that drop well below zero. Along with the cold temps the air is very dry and if people stay outside in...

Arctic haze is a phenomenon that occurs in the atmosphere at high latitudes in the Arctic due to air pollution. What distinguishes Arctic haze from haze found elsewhere, is the ability of its chemical ingredients to endure in the atmosphere for a longer period of time compared to other pollutants. Due to limited snowfall, rain, or turbulent air to displace pollutants from the polar air in the spring, Arctic haze can continue for more than a month in the northern atmosphere. Arctic haze was...

The Common Redpoll (Carduelis flammea), is a species in the finch family. It breeds throughout northern North America and Eurasia. Subspecies of the Common Redpoll include the Arctic Redpoll and Mealy Redpoll. These are common too in the Arctic, Iceland, Greenland, and Baffin Island. They all migrate south into southern Canada, northern United States and most of Eurasia. These birds are remarkably resistant to cold temperatures and winter migration is mainly due to lack of food rather...

The Arctic fox (Alopex lagopus), also known as the polar fox, is a small fox native to cold Arctic regions of the Northern Hemisphere. It is common in all three tundra biomes. Although some authorities have suggested placing it in the genus Vulpes, it has long been considered the sole member of the genus Alopex. The Arctic fox has smaller, more rounded ears, a more rounded braincase. It has a slightly shorter and broader muzzle than the red fox. Its feet are furrier than those of other...
