Ice Age Did Not Stop The Arctic Current From Flowing
2013-05-30 05:30:24

April Flowers for redOrbit.com - Your Universe Online When thick ice covered the Arctic during the last ice age, many scientists assumed that the deep currents below the ice that feed the North Atlantic Ocean and help drive the global ocean currents slowed or possibly even stopped. A new study reveals that the deep Arctic Ocean has been churning briskly for the last 35,000 years, through the chill of the last ice age and warmth of modern times. These findings, published in the journal...

There is growing recognition that reductions in Arctic sea ice levels will influence patterns of atmospheric circulation both within and beyond the Arctic. New research in the International Journal of Climatology explores the impact of 2007 ice conditions, the second lowest Arctic sea ice extent in the satellite era, on atmospheric circulation and surface temperatures. Two 30-year simulations, one using the sea ice levels of 2007 and another using sea ice levels at the end of the 20th...

Greenpeace Aims To Protect The North Pole With "Flag For The Future"
2013-04-15 15:53:56

Lee Rannals for redOrbit.com — Your Universe Online In 2007, Russian explorers dived down below the North Pole in a submersible and planted a national flag to make the point that it had rights to the energy riches of the Arctic. Now, a group of activists planted a "Flag For The Future" in the same area. The move by the environmentalists, backed by Greenpeace, is meant to try and declare the region "a global sanctuary" that is "free from exploitation." The group also...

Researchers Predict Sea Ice-Free Arctic Summers By 2050
2013-04-13 08:18:46

April Flowers for redOrbit.com — Your Universe Online The question of ice-free summers in the Arctic, for most scientists, is not "if," but "when." A new study by two National Oceanic and Atmospheric Administration (NOAA) scientists says that "when" is coming sooner than many thought. Already, the Arctic has experienced a loss of thick, multi-year ice, with last September´s extent being less than half the average of 1979-2000. The scientists, James Overland...

Harvard researchers are adding statistical nuance to our understanding of how modern and historical temperatures compare. Through developing a statistical model of Arctic temperature and how it relates to instrumental and proxy records derived from trees, ice cores, and lake sediments, Martin Tingley, a research associate in Harvard's Department of Earth and Planetary Sciences and Peter Huybers, Professor of Earth and Planetary Sciences, have shown that the warmest summers in the last two...

Study Calculates Arctic Ocean Nutrient Budget
2013-04-09 14:57:13

National Oceanography Centre, Southampton (UK) The first study of its kind to calculate the amount of nutrients entering and leaving the Arctic Ocean has been carried out by scientists based at the National Oceanography Centre, Southampton. Their results, which are published this month in the Journal of Geophysical Research, show that there is a mismatch between what goes into the Arctic Ocean and what comes out. This is the first study to look at the transport of dissolved inorganic...

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...
