NASA ice images aid study of Pacific walrus arctic habitats

Changes in climate are causing alterations in sea ice formation resulting in a changing habitat for Pacific walrus. Researchers will present findings from a joint NASA-US Fish and Wildlife Service study that assessed the use of satellite imagery for studying walrus habitat on sea ice. American Geophysical Union meeting (session H23I-05), December 12 at 5:50 p.m. EST.

1. Arctic ice retreats into uncharted territory
   09-27-2007 · EurekAlert!
   On Oct. 1, the National Snow and Ice Data Center will issue a report summarizing the 2007 Arctic sea ice season, and NASA will issue a press release on a new sea ice study by NASA/JPL researchers. NASA has created new images in support of these and other reports about the remarkable decrease in sea ice this summer.

2. MCA backs closure of Arctic waters
   06-12-2007 · EurekAlert!
   The Marine Conservation Alliance supports action today by the North Pacific Fishery Management Council to close all federal waters north of the Bering Strait to commercial fishing until a management plan, including habitat protection, is fully developed."Climate change is having a significant effect on the Arctic, opening previously ice-covered waters and drawing cold water species further north," said MCA's Dave Benton. "The council is right to look at closing these waters as a precautionary measure."

4. Investigating the invisible life in our environment
   02-01-2007 · EurekAlert!
   A new computational method to analyse environmental DNA samples, developed by researchers at the European Molecular Biology Laboratory (EMBL) in Heidelberg, now sheds light on the microbial composition of different habitats, from soil to water. The study, which will be published in this week’s online issue of the journal Science, also reveals that microbes evolve faster in some environments than in others and that they rather rarely change their habitat preferences over time.

8. Older Arctic sea ice replaced by young, thin ice, says CU-Boulder study
   01-10-2008 · EurekAlert!
   A new study by University of Colorado at Boulder researchers indicates older, multiyear sea ice in the Arctic is giving way to younger, thinner ice, making it more susceptible to record summer sea-ice lows like the one that occurred in 2007.

10. NASA mission checks health of Greenland's ice sheet and glaciers
    05-30-2007 · EurekAlert!
    A NASA-led research team has returned from Greenland after an annual three-week mission to check the health of its glaciers and ice sheet. About 82 percent of Greenland is made up of a giant ice sheet. During the Arctic Ice Mapping Project, researchers measured critical areas of the island's ice sheet as well as its glaciers and monitored changes that may be connected to global climate change.
