Arctic ice level down to a fifth since 1980

Washington, Feb 14 (IANS) The Arctic has lost more than a third of summer sea-ice volume since a decade ago, and is only a fifth of what it was in 1980, according to satellite observations.

Arctic ice level down to a fifth since 1980

Feb 14 2013, 1:58am CST | by

Washington, Feb 14 (IANS) The Arctic has lost more than a third of summer sea-ice volume since a decade ago, and is only a fifth of what it was in 1980, according to satellite observations.

Washington, Feb 14 — The Arctic has lost more than a third of summer sea-ice volume since a decade ago, and is only a fifth of what it was in 1980, according to satellite observations.

"What this new paper shows is that our ice loss estimates may have been too conservative, and that the recent decline is possibly more rapid," said study co-author Axel Schweiger, polar scientist in the University of Washington (UW) Applied Physics Lab.

"Other people had argued that 75 to 80 percent ice volume loss was too aggressive," said Schweiger, the journal Geophysical Research Letters reports.

Arctic sea ice is shrinking and thinning at the same time, Schweiger explained, so it's normal for the summer ice volume to drop faster than the area covered, according to a Washington statement.

The system developed at Washington provides a 34-year monthly picture of what's happening to the total volume of Arctic sea ice.

The Pan-Arctic Ice Ocean Modelling and Assimilation System, or PIOMAS, combines weather records, sea-surface temperature and satellite pictures of ice coverage to compute ice volume.

It then verifies the results with actual thickness measurements from individual moorings or submarines that cruise below the ice.

"Because the ice is so variable, you don't get a full picture of it from any of those observations," Schweiger said.

"So this model is the only way to reconstruct a time series that spans multiple decades."

The UW system also checks its results against five years of precise ice thickness measurements collected by a specialized satellite launched by NASA in 2003.

The Ice, Cloud, and Land Elevation Satellite, or ICESat, measured ice thickness across the Arctic to within 15 inches until spring of 2008.

Backed by tribes and a trash company, MicroGreen raises $17M for recycled cups

More than 58 billion disposable coffee cups are thrown out every year, and 20 million trees were cut down to make them. Arlington-based MicroGreen Polymers announced recently that it has raised $17 million to support a technology that would change that. The company, founded in the late 1990s by University of Washington graduate student Krishna Nadella, found a way to turn the plastic from recycled water bottles into recy ...

Looking out, looking in: UW researchers develop sensor that can be embeded in your eye

Jun 16 2014 2:06pm CDT | Source: Seattle Business Journal

Engineers at the University of Washington have designed a high-tech sensor that can be permanently embedded in a glaucoma patient’s eye to track critical pressure changes. After being embedded with an artificial lens during cataract surgery, the sensor provides immediate feedback on changes in the eye that are usually difficult to track. “No one has ever put electronics inside the lens of the eye, so this is a little more rad ...
