Jakobshavn Isbrae glacier

Glacier in Western Greenland. The Ilulissat Glacier has the largest concentration of supraglacial lakes on the ice sheet and is responsible for 7 percent of mass loss for the ice sheet. The goal of the study was to better understand how temperature, data that is typically more accessible, relates to the volume ...

They work on the Jakobshavn Glacier, one of the world's fastest-melting glaciers. It produces more than 10 per cent of Greeland's icebergs. It is an unpredictable environment. In 2015, a 12.5 square kilometre iceberg broke off and floated out to sea. Assuming that the ice was about 1,400 metres deep, ...

NOVA takes a helicopter over Greenland with David Holland, of New York University, and mountaineer Brian Rougeux, for a dangerous trip to research the rapidly disintegrating Jakobshavn Glacier. The loss of polar ice is causing sea levels to rise in ways that could devastate cities and communities ...

The scientists' first suggestion concerns Jakobshavn – Greenland's biggest and fastest-moving glacier and the largest contributor to the sea-level rise of any ... Warmer currents from the Atlantic are melting the glacier's base, so the scientists propose building a wall up to 100m tall in front to prevent the warm ...

“They're not coming out of nowhere saying things that don't make sense,” she said. “The three mechanisms imitate nature in slowing ice discharge to the sea.” And the three glaciers they suggest focusing on -- the Jakobshavn glacier in western Greenland, and the Pine Island and Thwaites glaciers in West ...

The Jakobshavn glacier in western Greenland is one of the fastest-moving ice masses on Earth. It contributes more to sea-level rise than any other glacier in the Northern Hemisphere. Ice loss from Jakobshavn explains around 4% of twentieth-century sea-level rise, or about 0.06 millimeters per year.

The Jakobshavn glacier alone drains about seven per cent of that ice sheet through two processes: direct melt into the ocean, and calving (when big chunks - totalling 35bn tonnes a year - of ice break off the front of the glacier). The balance over a year between the rate of ice loss on one hand, and of snow ...

Some scientists are suggesting pretty insane solutions to prevent total glacier meltdown, as Futurism reports. One idea is to create a wall and wrap it across the five-kilometer fjord in front of Greenland's Jakobshavn glacier. Its goal? To block warm water from reaching the sea. There are other similarly ...

An iceberg from Greenland's Jakobshavn Glacier is thought to have been responsible for sinking the Titanic in 1912, for example. But now boats are running into trouble because of sea ice getting flushed out of the Arctic. "The warming in the Arctic and decline in ice cover is increasing the ability of this ice to ...

The first of the cockamamy, desperate schemes: a wall 100 meters (330 feet) high, built across the 5-kilometer (62-mile) fjord in front of Greenland's Jakobshavn glacier. Its purpose: to block warm water from reaching the sea. There are other proposals laid out in a Nature article that advocates for extreme ...

To stem melting at the Jakobshavn glacier in western Greenland – the biggest glacial contributor to sea-level rise in the Northern Hemisphere – the team wants to build a mammoth wall underwater. Standing 100 metres high above the surface of the ocean floor, this epic barrier would stretch the 5-kilometre ...

For example, building a dam across the Jakobshavn fjord could affect ecology, fisheries and tourism, and large numbers of workers would have to be shipped in to complete the project. Similarly, building artificial islands in front of glaciers would mean importing about six cubic kilometres of material, a task ...

“Earth – Power of the Planet – Ice”: This film explores the Jakobshavn glacier from below to discover how it shaped our past and may affect our future. 4 p.m. Saturday, March 17, Beckman Auditorium, Caltech, 332 S. Michigan Ave., Pasadena, $10, recommended for ages 8 and up, 626-395-4652, ...

We think that geoengineering of glaciers on a similar scale could delay much of Greenland and Antarctica's grounded ice from reaching the sea for centuries, buying time to address global warming. In our ... The Jakobshavn glacier in western Greenland is one of the fastest-moving ice masses on Earth.

The Jakobshavn Glacier is a large valley glacier in west Greenland. It moves about 100 feet (30 meters) a day, making it one of the fastest-moving glaciers in the world, according to Smithsonian Ocean Portal. The Jakobshavn drains 6.5 percent of the Greenland ice sheet and produces about 10 percent of ...
