Luxury Cruise to Embark on Unprecedented 32-day Arctic Expedition LOS ANGELES, July 17, 2014 /PRNewswire/ -- The "World's Best" Crystal Cruises is introducing a new expedition-style voyage traversing the Arctic Ocean via the legendary Northwest Passage - one so mysterious and remote (500 miles north of the Arctic Circle), that explorers spent centuries seeking the passage, until it was first completed successfully by Roald Amundsen just over 100 years ago....

Satellite Imagery A Promising Tool To Monitor Arctic Polar Bears
2014-07-10 03:14:50

PLOS Polar bear population estimates based on satellite images are similar to aerial estimates, according to a study published July 9, 2014 in the open-access journal PLOS ONE by Seth Stapleton from United States Geological Survey and colleagues. The potentially severe impacts of climate change in the Arctic may threaten regional wildlife. Scientists trying to develop efficient and effective wildlife monitoring techniques to track Arctic populations face great challenges, including the...

April Flowers for redOrbit.com - Your Universe Online Today, polar bears and other animals adapted to extremely cold environments inhabit the Arctic tundra. In the past, around 53 to 38 million years ago (the Eocene epoch), the Arctic was not a frozen tundra -- rather, it was more like a huge temperate forest with brackish water. This forest was home to a wide variety of wildlife, including the ancestors of modern-day tapirs, hippo-like creatures, crocodiles and giant tortoises....

April Flowers for redOrbit.com - Your Universe Online Most sharks today are strictly saltwater fish, however, a new study led by the University of Colorado Boulder and the University of Chicago reveals that this was not the case 50 million years ago. Sharks in the Arctic Ocean during this time lived in brackish water, with approximately the same amount of freshwater found in modern day Lake Ponchatrain in Louisiana. The study, led by University of Chicago postdoctoral researcher Sora...

Study Shows Earlier Snowmelt Is Prompting Arctic Birds To Breed Earlier

Wildlife Conservation Society WCS study shows earlier spring seasons brought about by climate change causing long-distance migrants to breed sooner A new collaborative study that included the work of Wildlife Conservation Society (WCS) biologists has revealed that migratory birds that breed in Arctic Alaska are initiating nests earlier in the spring, and that snowmelt occurring earlier in the season is a big reason why. The report, "Phenological advancement in arctic bird species:...

Arctic Amplification Has Reduced Risk Of Extreme Cold Weather

redOrbit Staff & Wire Reports - Your Universe Online Despite the fact that many parts of the United States experienced extremely cold conditions this past winter, the risk of such conditions increasing as a result of climate change is unlikely, according to research appearing in the latest edition of Nature Climate Change. Study author Dr. James Screen of the University of Exeter reports that the Arctic amplification phenomenon, which refers to the increased warming rate experienced...

Gerard LeBlond for redorbit.com - Your Universe Online Over the past 2.5 million years, the Earth has gone through changes in climate. Warm and cold cycles, some lasting for millennia, have become known as the Ice Age. During the cold cycles, ice sheets covered large areas of the northern hemisphere and as the ice melted during the warm cycles, the glaciers receded leaving huge valleys behind. These cycles also affected the evolution and distribution of animals, including the ones living...

Melting Arctic Sea Ice Opens New Passages For Invasive Species
2014-05-28 03:24:06

Smithsonian Scientists say early action could protect coasts For the first time in roughly 2 million years, melting Arctic sea ice is connecting the north Pacific and north Atlantic oceans. The newly opened passages leave both coasts and Arctic waters vulnerable to a large wave of invasive species, biologists from the Smithsonian Environmental Research Center assert in a commentary published May 28 in Nature Climate Change. Two new shipping routes have opened in the Arctic: the...

Alaskan Hare, Lepus othus
2014-05-19 10:40:26

The Alaskan hare (Lepus othus), or the tundra hare, can be found on the Alaskan Peninsula and in western areas of Alaska. This species prefers to reside in rocky areas in their tundra habitat, resting in open areas rather than in burrows. It is most closely related to the mountain hare and the Arctic hare. Members of this species reach an average weight between 1.6 and 2.2 feet, with hind feet that reach a length of 7.9 inches. The hind feet are thought to help the hares move quickly and...

Arctic Ocean

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...
