Most detailed seafloor depth map of Arctic Ocean released

An international team of researchers released the most detailed seafloor depth map of the Arctic Ocean. The map, which is the 4.0 version of the International Bathymetric Chart of the Arctic Ocean (IBCAO), expands up to 19.6 percent of the submarine surface mapped...

Phytoplankton blooms on the rise across Arctic Ocean

NASA's Terra and Aqua satellites captured a majestic shot of blooms of phytoplankton showing up in higher concentrations across the Arctic Ocean this summer. Every summer, parts of the Arctic Ocean and surrounding seas lose their ice cover and bask in ample...

Shallow M6.0 earthquake hits north of Franz Josef Land, Arctic Ocean

A strong and shallow earthquake registered by the USGS as M6.0 hit north of Franz Josef Land, Arctic ocean at 19:11 UTC on October 28, 2017. The agency is reporting a depth of 10 km (6.2 miles). EMSC is reporting the same magnitude and depth. This is the third...

Beginning of Arctic sea ice melting season

The average extent of sea ice in the Arctic has begun shrinking and will probably reach its minimum extent sometime in mid-September. Arctic sea ice reached this year's maximum extent on March 15 at 15.13 million square kilometers (5.84 million square

Unexpected discovery - Arctic Ocean is richer in microscopic plants than any other ocean on Earth

Scientists have made a biological discovery in Arctic Ocean waters as dramatic and unexpected as finding a rainforest in the middle of a desert. A NASA-sponsored expedition punched through three-foot thick sea ice to find waters richer in microscopic marine plants,

Circumpolar rivers most responsible for high levels of mercury in the Arctic

Toxic mercury in the arctic, long thought to be coming primarily from atmospheric sources, is also being carried into the region by rivers. The Arctic accumulation of toxic mercury is caused by both atmospheric forces and the flow of circumpolar rivers that carry the

Arctic shipping routes open

Satellite measurements show we are heading for another year of below-average ice cover in the Arctic. As sea ice melts during the summer months, two major shipping routes have opened in the Arctic Ocean.In 2008 satellites saw that the Northwest Passage and the Northern

The glaciers on the islands of Franz Josef are currently in a state of retreat

The clouds parted over the northeast Barents Sea region of the Arctic Ocean in late summer, 2011 allowing a view of the ice-covered islands of Franz Josef Land, Russia forming a stark-white contrast to the surrounding dark sea water. The Moderate Resolution Imaging

Large variations in Arctic sea ice

For the last 10,000 years, summer sea ice in the Arctic Ocean has been far from constant. For several thousand years, there was much less sea ice in The Arctic Ocean - probably less than half of current amounts. This is indicated by new findings by the Danish National

2011: Headed for record Arctic melt?

This year could be well on its way toward earning a dubious spot in the record books.Arctic sea ice has melted away with astonishing speed in the first half of July, at an average rate of about 46,000 square miles (120,000 square kilometers) per day, according to the Na

Mercury converted to its most toxic form in ocean waters

University of Alberta-led research has confirmed that a relatively harmless inorganic form of mercury found worldwide in ocean water is transformed into a potent neurotoxin in the seawater itself.After two years of testing water samples across the Arctic Ocean, the

New York 'at risk' as seas rise

New York is a major loser and Reykjavik a winner from new forecasts of sea level rise in different regions.The Intergovernmental Panel on Climate Change (IPCC) said in 2007 that sea levels would rise at least 28cm (1ft) by the year 2100. But this is a global average;

Arctic Ocean freshwater will cause 'unpredictable changes on climate'

A vast expanse of freshwater in the midst of the Arctic Ocean is set to wreak unpredictable changes on the climate in Europe and North America, new scientific analysis has shown.The water – comprising meltwater from the ice cap and run off from rivers – is at

Arctic ocean show significant increase in freshwater content

Since the 1900, the freshwater content of the upper Arctic Ocean has increased by about 20 %. This corresponds to a rise of approx. 8,400 cubic kilometres and has the same magnitude as the volume of freshwater annually exported on average from this marine region in

Arctic's spring phytoplankton blooms arrive earlier

When summer comes to the Arctic, the tiny plants that feed the ocean's food chain form green blooms in the water. In some Arctic waters, the peak of this bloom has been arriving earlier every year since 1997, a study has found. These areas, where peak bloom
