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.

Smart devices that lack a battery or wire connection but can still send data over Wi-Fi, have been created by computer scientists. Experts from the University of Washington have developed a way of using radio frequency (RF) signals as a power source for smart devices and reusing existing Wi-Fi infrastructure to provide connectivity to them. Currently, RF-powered devices require a dedicated gateway such as an RFID read ...

Weaving HIV protection: UW researchers use fabric to protect women against infection

Aug 4 2014 4:05pm CDT | Source: Seattle Business Journal

University of Washington bioengineers have developed a technology that could help better protect women from contracting HIV. The secret is using a new fabric to deliver high doses of a drug currently being tested for staving off the infection. Scientists use a method of weaving the drug into silk-like fibers that dissolve quickly when inserted into the vagina before sex, delivering a higher dose than is possible with othe ...

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 recyclable coffee cups. Clean tech has been gaining steam, especially in th ...
