Mathematician uses skills to study Greenland’s retreating glaciers – Science Nation

♫MUSIC♫ MILES O’BRIEN: Dodging icebergs in Greenland’s Jackobshavn Icefjord is all in a day’s work for Mathematician David Holland. With support from the National Science Foundation, Holland and his team from New York University are crisscrossing the mouth of the fjord, lowering a probe deep under water to gather data on salinity, temperature, pressure and other factors. DAVID HOLLAND: The

Dark Ice on Greenland Could Mean Faster Rise in Sea Levels

Dark Ice on Greenland Could Mean Faster Rise in Sea Levels

I’m Gabe Garza with today’s health news. The continuous darkening of Greenland’s ice is causing sea levels to rise at faster rates. Ice on Greenland’s surface is currently in a “feedback loop” in which it melts faster as it darkens, according to researchers from Columbia University’s Lamont-Doherty Earth Observatory in Palisades, New York. The darker color is a result of

What’s hidden under the Greenland ice sheet? | Kristin Poinar

What’s hidden under the Greenland ice sheet? | Kristin Poinar

When was I was 21 years old, I had all this physics homework. Physics homework requires taking breaks, and Wikipedia was relatively new, so I took a lot of breaks there. I kept going back to the same articles, reading them again and again, on glaciers, Antarctica and Greenland. How cool would it be to visit these places and what

NASA | GROVER in Greenland

The robot consists of two snowmobile tracks and two solar panels. It’s not a robot for the sake of building a robot. But it’s a robot for science. The climate is changing and snow is really important because it reflects a lot of the energy and heat from the sun. Places like Greenland which are covered in snow are very

ScienceCasts: Greenland’s Thinning Ice

[ MUSIC ] Greenland’s Thinning Ice – presented by [email protected] With temperatures around the world climbing, melt waters from the continental ice sheets of Greenland and Antarctica are raising sea levels. Those ice sheets are melting from both above and below. Much of the ice lost from ice sheets comes from a process called calving where ice erodes, breaks off,

Meet Greenland – S1 Episode 1 – Organisation de l’expédition

After a first expedition, we are going back to Greenland. Last year we went to south region, this time we are going to east just under the artic circle. This year as we are going further north greenland, it is totally different kind of logistic, because we need to take under considaration the climate,colder. It also an isolated land where

Prof Jonathan Bamber on ‘tipping points’ for Greenland and Antarctic glaciers

The Greenland ice sheet is a relic of the last glacial period, which ran from about 130,000 years ago to 12,000 years ago. There’s this thing called the “small ice cap instability”. What that means is, as you warm air temperatures, you’re going to melt some ice and the surface of the ice sheet is going to go down a

Drone images show Greenland ice sheet becoming more unstable as it fractures

Drone images show Greenland ice sheet becoming more unstable as it fractures

The world’s second-largest ice sheet, and the single largest contributor to global sea-level rise, is potentially becoming unstable because of fractures developing in response to faster ice flow and more meltwater forming on its surface. Using custom-built drones strong enough to withstand the extreme Arctic conditions, researchers led by the University of Cambridge made the first drone-based observations of how

Greenland Ice Sheet Changing

Greenland Ice Sheet Changing

Greenland, the world’s largest island, extends over an area more than one quarter the size of the continental United States. Although sparsely populated, it holds the potential to impact populations around the world. The Greenland Ice Sheet, covering three quarters of the country in ice up to 3 kilometers thick, would increase global sea level by 7.2 meters if it
