That year, the late Mercer, a glaciologist at Ohio State University in Columbus, first warned about the potential for rapid sea-level rise from melting ice caps. His landmark paper drew on fieldwork at the Reedy Glacier, which feeds into West Antarctica's Ross Sea (J. H. Mercer Int. Assoc. Sci. Hydrol. Symp.

The findings, by a Stanford-led team of radar engineers and geophysical glaciologists, came from radar data collected at the same locations in 2004, 2012 and 2014, each revealing details of the glaciers miles below the surface. The surveys show that ocean water is reaching beneath the edge of the Pine ...
glaciologists hadn't quite believed that glaciers could behave this way, and suddenly they had witnessed two similar collapses in a year. An analysis of the events, published this week in the journal Nature Geoscience, found that climate change was the culprit in both collapses. The study suggests that in ...

Writing in the journal Geophysical Research Letters, a publication of the American Geophysical Union, a team of glaciologists led by Aberystwyth University in Wales have shown that the ponds, which form on debris-covered glaciers in the Himalaya, control the rate at which water from melting ice flows ...
"It's very complicated and hazardous to navigate in and that's been one of the impediments to sending robotic submarine missions that do not have autonomous navigation technology," Knut Christianson, glaciologist on the project from the University of Washington, told Newsweek. "There's no guarantee ...
glaciologists have long known materials such as mineral dust and black carbon can darken the surface of large ice sheets. scientists study these impurities because they reduce the sheet's albedo, or the extent to which it reflects light, which increases melting of the ice and affects projections of sea level ...
Hydrologists and glaciologists have traditionally used fluorescent dyes, or salts such as sodium chloride, to track water systems including melting ice. But such tracers have limitations, especially in a place like the Greenland ice sheet. When researchers drop them in a location, some of the dyes and salts ...

"We have almost no information about the area where the glacier is floating on top of the ocean," said glaciologist Knut Christianson, a UW assistant professor of Earth and space sciences. "The ice is 300 to 500 meters (1/5 to 1/3 of a mile) thick. There's no light penetrating, it's impossible to communicate ...
glaciologists call these frozen columns "ice cores." The shortest are usually around 328 feet (100 meters) long, but cores stretching more than 2 miles (3.2 kilometers) from end to end have also been collected. During the extraction process, a core is broken up into smaller pieces, which are then placed into ...
With the world still nowhere near the emissions reductions needed to stave off significant global warming, Princeton University glaciologist Michael Wolovick thinks it's not a bad idea to consider other ways to forestall marine ice sheet collapse. This week, he is presenting as-yet unpublished research that ...

"We predicted that the rifting would result in more frequent calving, which is what's happening here," glaciologist Ian Howat of Ohio State University told The Washington Post in September when the iceberg cut loose. "If new rifts continue to form progressively inland, the significance to ice shelf retreat would ...
"Ice is only so strong, so it will collapse if these cliffs reach a certain height," explains Kristin Poinar, a glaciologist at NASA's Goddard Space Flight Center. "We need to know how fast it's going to happen." In the past few years, scientists have identified marine ice-cliff instability as a feedback loop that could ...
The iceberg now seems like a large chunk of ice, "but it will become a threat" since it will move out to sea and break up into smaller pieces, said Ricardo Jana, a glaciologist at the Chilean National Antarctic Institute. Given its size, the smaller icebergs likely to break off can create problems for area ...
