A University of Alaska Fairbanks-led research team has developed a way to use satellite images to determine the amount of methane being released from northern lakes, a technique that could help climate change modelers better account for this potent greenhouse gas. By using synthetic aperture radar, or SAR, researchers were able to find a […]

Using data from the ICESat and ICESat-2 laser altimeters, scientists precisely measured how much ice has been lost from ice sheets in Antarctica and Greenland between 2003 and 2019. The Antarctic Peninsula, seen here, was one of the fastest changing regions of the continent. Credits: NASA / K. Ramsayer The results provide insights into how […]

The Arctic has experienced the warming effects of global climate change faster than any other region on the planet. Scientists at the Scripps Institution of Oceanography have developed a new theory aided by computer simulations and observations that helps explain why this occurs. A team led by Scripps researcher Emma Beer observed the changes taking place […]
When two National Hockey League hockey players collide, their pads and body tissues can absorb enough energy to power a 100-watt light bulb for a minute and a half. During the 60 minutes of a hockey game, players can burn 6,000 calories and lose up to 15 pounds. These are the calculations of Alain […]
The North Pacific Fishery Management Council has approved final action to allow vessels to deliver a partial load of crab and then continue harvesting under the crab rationalization program. The council reasoned during its December meeting in Anchorage, Alaska, that being able to resume fishing after a partial offload could help vessels faced with […]
