NASA's Operation IceBridge Concludes 2015 Arctic Campaign

June 3, 2015 — Operation IceBridge wrapped up its seventh Arctic deployment on May 21, when NASA's C-130 research aircraft with the mission's researchers and instruments on board departed Thule Air Base ... read more

Snow and Avalanche Research: Remote Assessment of Avalanche Risk

May 5, 2015 — Geographers have developed a novel measuring system relying on two different physical methods that promises to enhance forecasting of avalanches and spring floods. The method combines GPS and radar ... read more

Apr. 30, 2015 — Researchers 'weighed' Antarctica's ice sheet using gravitational satellite data and found that during the past decade, Antarctica's massive ice sheet lost twice the amount of ice ... read more

Apr. 30, 2015 — A multinational study attempted to gauge the population trends of Arctic marine mammals and changes in their habitat, identify missing scientific information, and provide recommendations for the ... read more

Apr. 29, 2015 — A new study using evidence from a highly detailed ice core from West Antarctica shows a consistent link between abrupt temperature changes on Greenland and Antarctica during the last ice age, giving ... read more

Apr. 28, 2015 — Some scientists have suggested that global warming could melt frozen ground in the Arctic, releasing vast amounts of the potent greenhouse gas methane into the atmosphere, greatly amplifying global ... read more

Phytoplankton, Reducing Greenhouse Gases or Amplifying Arctic Warming?

Apr. 21, 2015 — Scientists have presented the geophysical impact of phytoplankton that triggers positive feedback in the Arctic warming when the warming-induced melting of sea ice stimulates phytoplankton ... read more

Apr. 20, 2015 — Before Deepwater Horizon, scientists didn't know that oil and marine snow had anything to do with each other. "Marine snow is like dust bunnies in the house," explained a research ... read more

How Radiative Fluxes Are Affected by Cloud and Particle Characteristics

Apr. 17, 2015 — Climate models calculate a changing mix of clouds and emissions that interact with solar energy. To narrow the broad range of possible answers from a climate model, researchers analyzed the effect of ... read more

Apr. 17, 2015 — Darkening of the Greenland Ice Sheet is projected to continue as a consequence of continued climate warming, according to ... read more

New Method Relates Greenland Ice Sheet Changes to Sea-Level Rise

Apr. 14, 2015 — Early schemes to model the Greenland and Antarctic ice sheets and their impact on sea levels failed to accurately account for changes caused by snowfall and snow melt. These changes depend on ice ... read more

Mar. 27, 2015 — Cold snaps like the ones that hit the eastern United States in the past winters are not a consequence of climate change. Scientists have now shown that global warming actually tends to reduce ... read more

Mar. 26, 2015 — A new study has revealed that the thickness of Antarctica's floating ice shelves has recently decreased by as much as 18 percent in certain areas over nearly two decades, providing new insights ... read more

Mar. 16, 2015 — Researchers have discovered two seafloor gateways that could allow warm ocean water to reach the base of Totten Glacier, East Antarctica's largest and most rapidly thinning glacier. The ... read more

Past Warming Increased Snowfall on Antarctica, Affecting Global Sea Level

Mar. 16, 2015 — A new study confirms that snowfall in Antarctica will increase significantly as the planet warms, offsetting future sea level rise from other sources -- but the effect will not be nearly as strong as ... read more

Mar. 10, 2015 — Fresh off the recent successful deployment of its 20-foot (6-meter) reflector antenna and associated boom arm, NASA's new Soil Moisture Active Passive (SMAP) observatory has successfully ... read more

Friction Means Antarctic Glaciers More Sensitive to Climate Change Than We Thought

Mar. 10, 2015 — A new study finds that incorporating Coulomb friction into computer models increases the sensitivity of Antarctic ice sheets to temperature perturbations driven by climate ... read more

Mar. 6, 2015 — Researchers measure underwater noise in Alaskan and Antarctic fjords and find them to be the noisiest places in the ocean. This leads researchers to ask how animals such as whales and seals use the ... read more

Mar. 5, 2015 — When you walk on the beach, the sand supports your weight like a solid. What happens to the forces between the sand grains when you step on them to keep you from sinking? Researchers have developed a ... read more

Mar. 4, 2015 — A new study finds that climate change and past hunting in the remote Tibetan Plateau is forcing female wild yaks onto steeper and steeper ... read more
