Prepping for radar vision
Sentinel-1A, Europe's first satellite for Copernicus, is almost ready for launch on 3 April. Meanwhile, ESA is showing how its advanced radar will map ice, monitor subsidence and much more.
First assessment of noctilucent cloud variability at midlatitudes
As the Sun dips below the horizon, the last rays of light can glint off crystals of ice high in the atmosphere, lighting up the sky with an electric blue glow. Known as noctilucent clouds, these collections ...
Geographers create 'easy button' to calculate river flows from space
(Phys.org) —The frustrated attempts of a UCLA graduate student to quantify the amount of water draining from Greenland's melting ice sheet led him to devise a new way to measure river flows from outer space, ...
Dolphin pod dies trapped in ice off Canadian coast
Some 30 white-beaked dolphins have died after being trapped in ice off the coast of Canada's easternmost Newfoundland province, and three remaining alive are not faring well, officials said Monday.
Unearthing a fossil haven
Seventy feet below Wilshire Boulevard, catercorner from the Los Angeles County Museum of Art's street-lamp installation, fresh air roaring from giant ventilation pipes dulled the sickly sweet smell of petroleum.
Greenland implicated further in sea-level rise
An international team of scientists has discovered that the last remaining stable portion of the Greenland ice sheet is stable no more.
Vanishing ice warning for 'Africa's Alps'
In swirling snow, John Medenge prods a thin ice bridge over a crevasse with an iron-tipped spear, guiding climbers scaling the steep glacial wall using crampons and axes.
IceBridge starts with sea ice surveys
NASA's Operation IceBridge started the 2014 Arctic campaign with two surveys of sea ice north of Greenland. The two flights follow similar surveys flow in previous years and continue the mission's goals of ...
Charting Icelandic glacier dynamics
Mark Simons, professor of geophysics at Caltech, along with graduate student Brent Minchew, recently logged over 40 hours of flight time mapping the surface of Iceland's glaciers. Flying over two comparatively ...
Researcher develops more accurate method to measure surface meltwater volume of Greenland ice sheet
(Phys.org) —A University of Wyoming researcher discovered that using satellite imagery to map the depth of melt ponds and melt-water stream channels on the surface of the Greenland ice sheet could become ...
Computer model predicts vastly different ecosystem in Antarctica's Ross Sea in the coming century
The Ross Sea, a major, biologically productive Antarctic ecosystem, "clearly will be extensively modified by future climate change" in the coming decades as rising temperatures and changing wind patterns ...
How wind helps Antarctic sea ice grow, even as the Arctic melts
Strong winds linked to climate change and the hole in the ozone layer are driving a steady increase in Antarctic sea ice, even as Arctic levels continue to shrink dramatically, a new report shows.
First thin films of spin ice reveal cold secrets
Thin films of spin ice have been shown to demonstrate surprising properties which could help in the development of applications of magnetricity, the magnetic equivalent of electricity.
NASA data shed new light on changing Greenland ice
Research using NASA data is giving new insight into one of the processes causing Greenland's ice sheet to lose mass. A team of scientists used satellite observations and ice thickness measurements gathered ...
