A prominent glaciologist will spend 10 days gathering driftwood from Baffin Island and West Greenland in hopes that the wood will reveal new information about ocean currents, sea-ice extent, and sea level changes. The logic behind the study currently under consideration by the Nunavut Impact ... Scientist

More snow now melts on Mt. Hunter than at any time in the past 400 years, said Dominic Winski, a glaciologist at Dartmouth College in Hanover, New Hampshire and lead author of the new study published in the Journal of Geophysical Research: Atmospheres, a journal of the American Geophysical Union. Arctic
"We have not seen snow melt like this in at least four centuries," lead author Dominic Winski, a glaciologist at Dartmouth College, told USA Today. For the study, Winski and 11 other researchers from Dartmouth College, the University of Maine and the University of New Hampshire examined ice cores ...
Dominic Winski, a glaciologist at Dartmouth College and lead author of the study said in a statement on the American Geophysical Union (AGU) website: "The natural climate system has changed since the onset of the anthropogenic era," he said, referring to the era marked by the human impact on ...

Hunter than at any time in the past 400 years, Dominic Winski, a glaciologist at Dartmouth College in Hanover, New Hampshire and lead author of the new study, said in a news release on Tuesday. The new study's results show the Alaska Range has been warming rapidly ... Arctic
So a group of glaciologists is proposing a radical solution to buy us more time to reduce carbon emissions and adapt to climate change. ... John Moore, a glaciologist at Beijing Normal University in China, and his colleagues suggest three ways that the glaciers in Greenland and Antarctica contributing ...
Greenland is melting rapidly, but some glaciers are disappearing faster than others. A new map of the surrounding seafloor helps explain why: Many of the fastest-melting glaciers sit atop deep fjords that allow Atlantic Ocean water to melt them from below. Researchers led by glaciologist Romain Millan ...
It's tricky to estimate exactly when the massive chucks of ice will become extinct, but at least one glaciologist believes the glaciers of Iztaccihuatl, a dormant volcano and the country's third tallest, could be gone within the next decade—or even sooner.
“Ice cores can take us back centuries,” said Erich Osterberg, a Dartmouth glaciologist who led the research along with graduate student Karina Graeter. “It gives us that long-term context to see just how unusual is what's happening today.” Current melt rates may even be unprecedented over a time frame ...
“We understand the hesitancy to interfere with glaciers — as glaciologists, we know the pristine beauty of these places,” the authors continue. “But we have also stood on ice shelves that are now open ocean. If the world does nothing, ice sheets will keep shrinking and the losses will accelerate.” And even if ...
"We understand the hesitancy to interfere with glaciers — as glaciologists, we know the pristine beauty of these places," the group explains. "But we ...

Climate scientists and glaciologists from NIWA and Victoria University of Wellington have just completed their annual end of summer snowline flight over nearly 50 glaciers in the Southern Alps. ... In the late 1970s, glaciologist Dr Trevor Chinn carried out an inventory of all of New Zealand's glaciers.
The idea is that the white canvas blankets will be able to reflect sunlight away from the glacier. This might sound outlandish, but it's having a positive effect. Glaciologist David Volken told the Agence France-Presse (AFP) that the blankets can reduce the amount of ice that melts by around 70 percent, ...
Victoria University glaciologist Prof Andrew Mackintosh said he was expecting one of the largest melt years on record.

While the team mobilises for the expedition, glaciologists and remote sensing specialists continue to monitor the movement of the Larsen C Ice Shelf. In December 2017, a team from University of Leeds worked on the remaining ice shelf to investigate changes in ice structure after the calving event, to be ...
It's continuing to shrink by as much as 8 inches on a hot day, and has retreated some 20 feet in the last three weeks, Swiss glaciologist David Volken tells AFP. The dirty blankets, easily mistaken for ice from afar, reflect sunlight and may help reduce melting by up to 70%, per Quartz. They allow Rhone ...
While the blankets are certainly a low-tech solution to this particular global warming crisis, they do appear to be having some positive results. In 2015, David Volken, a glaciologist working with the Swiss environment ministry, said in an interview that the blankets have been reducing melt by as much as 70 ...
The blankets are a simple fix, but they seem to help — Swiss glaciologist David Volken has previously suggested to Agence France-Presse that they may reduce melting by up to 70 percent. Similar protective coverings are used on other glaciers, as well, in places like Italy and Germany — and scientists ...
Every summer for the last eight years, people who live in the Swiss Alps have been wrapping a beloved glacier in blankets. The white canvas blankets are intended to reflect sunlight off the Rhone Glacier, to try to reduce how much of it disappears each year. And Swiss glaciologist David Volken says it's ...
Glaciologists, in other words, are renaissance people, capable of winding knowledge around multiple lures. By the end of this story, though, our glaciologist may have encountered too many inter-disciplines colliding with the outcome of his current studies. “The Glacier” might just be an examination of some ...
The man who posted the video is one Peter Neff, a glaciologist. He has BSc ... Glaciologists serve a vital role in studying past, present and future changes in climate, and their work is of the utmost important when it comes to understanding our planet and the challenges it is up against, particularly with rising ...

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 ...

“As these glaciers develop more and more of these ponds that we can see on the surface, they will also develop voids inside the ice as well and it will become more porous and it will be able to hold more and more of that water back,” said Duncan Quincy, another glaciologist of Leeds University who was ...
Twenty years later, John Mercer, a glaciologist at Ohio State University, connected that unusual feature to the recent idea that humans were warming .... Glaciologists had once floated an idea to pump sea water into the middle of the Antarctica, so it could freeze solid and reduce the rise of global sea levels.
Steffan Danino talks to Harry Kemble about deep conversations with guests, and why Greenland remains such a special place to him. I start the day with… Let's say we are on a trip to Antarctica. The expedition staff will be up about half an hour before the guests. We get kitted up, then have breakfast, and ...
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 ...
