The Christian Science Monitor reports the findings of a study published June 3 in Nature that investigates how large glacial lakes in Greenland can completely drain billions of gallons of water in a matter of hours.
In Mark Twickler’s world, “small” is relative. When it comes to a new ice core drill that’s being developed and tested by a team of specialized engineers from the Ice Drilling Design and Operations group (IDDO), small means about 20,000 pounds.
For years, scientists have understood that Greenland's ice sheet contributes to rising sea levels through the combination of surface melting and accelerating outlet glaciers. What’s less understood is the behavior of different glaciers in different locations.
GROVER is an autonomous vehicle that can navigate to GPS coordinates and report back to base via satellite from any location in the world while it collects scientific information.
The unprecedented Arctic warming over the past 30 years is leading to melting of sea ice and consequences. Now scientists have evidence that Arctic warming could also change atmospheric chemistry through reactions that occur between the air and the snow.
The crew at Greenland’s Summit Station recently launched a tandem balloon to gather data for two ongoing research projects. To learn more about it, read on.
On the sea ice floating near the North Pole, scientists led by Jamie Morison (U Washington) is gearing up for annual springtime sampling activities that for the North Pole Environmental Observatory (NPEO). For more than a decade, this field work has taken place in April.
The New York Times is reporting today the results of a new study showing global temperatures are higher than they've been in the last 4,000 years and are likely to surpass levels not seen since the last Ice Age.
Changing weather events, rapidly shrinking ice coverage in the Arctic and fluxes in ocean temperature impact all of us. These occurrences also bring up a myriad of questions about long-term climate change, short-term weather patterns and their impact on regions like the Arctic.
Operation IceBridge takes scientists to new heights (literally!) to collect aerial ice cover data to help us better understand how changes in polar ice connect to the broader global climate system. The six-year project is the largest airborne survey of polar ice ever.
Aurorae, named for the Roman goddess of dawn, are a natural phenomenon occurring when charged particles, mostly electrons from the sun, enter the earth’s atmosphere where they are directed toward the polar regions by the Earth’s magnetic field.
