International study provides more solid measure of shrinking in polar ice sheets

Channel through glacier

Climatologists have reconciled their measurements of ice loss in Antarctica and Greenland during the past two decades. A second article looks at how to monitor and understand accelerating losses from the planet’s two largest continental ice sheets.

Novel scientific equipment will unlock ocean secrets for decades — with slide show

The shallow profiler will float to the surface and get pulled back down to the floating platform by a winch.

University of Washington engineers and scientists are one step closer to deploying sophisticated equipment that will collect important information about ocean properties like currents and temperature and send the information via the Internet in real time to scientists around the world.

Increasing speed of Greenland glaciers gives new insight for rising sea level

These icebergs recently calved from the front of the north branch of Jakobshavn Isbrae, a large outlet glacier that drains 6.5 percent of the Greenland ice sheet. The fact that they are upright, indicated by their dirty and crevassed surfaces, suggests they calved from the floating end of a glacier.

Changes in the speed that ice travels in more than 200 outlet glaciers indicates that Greenland’s contribution to rising sea level in the 21st century might be significantly less than the upper limits some scientists thought possible, a new study shows.

Kids can explore icy worlds with scientists at Polar Science Weekend (with video)

Taryn Black, a UW undergraduate, coaches two young visitors conducting an experiment to find out which block of ice is from fresh water and which from salt water.

Learn about polar bears and penguins. Center a two-foot tusk on your forehead and imagine youre a narwhal exploring your icy-ocean home. For these activities and more, grab the kids and head for Polar Science Weekend, March 1 to 4, sponsored by the UW’s Applied Physics Laboratory and Pacific Science Center.

While stability far from assured, Greenland perhaps not headed down too slippery a slope

In a pair of companion papers in Science Express this week, scientists investigate the role of surface meltwater on accelerating the flow of the Greenland Ice Sheet and outlet glaciers and conclude that, while surface melt plays a substantial role in ice sheet dynamics, it may not produce large instabilities.

Pacific Science Center in grips of polar blast March 2-5

With the extent of Arctic ice reaching record-breaking lows in recent seasons and Antarctic ice sheets losing dramatic, miles-wide pieces of ice, the world’s attention has been focused on changes underway at both ends of the Earth.
