Sentences with phrase «if glacier flow»

Not exact matches

All told, if the eastern and western Antarctic ice shelves were to melt completely, they would raise sea levels by as much as 230 feet (70 meters); the collapse of smaller shelves like Larsen B has sped up the flow of glaciers behind them into the sea, contributing to the creeping up of high tide levels around the world.

«If that happens, the glacier's flow could be significantly destabilized, causing it to discharge even more ice into the ocean,» he said.

One 2004 NASA - led study found that most of the glaciers they were studying «flow into floating ice shelves over bedrock up to hundreds of meters deeper than previous estimates, providing exit routes for ice from further inland if ice - sheet collapse is under way.»

On the other hand, if the ice shell is sufficiently thick, the less intense interior heat can be transferred to warmer ice at the bottom of the shell, with additional heat generated by tidal flexing of the warmer ice which can slowly rise and flow as do glaciers do on Earth; this slow but steady motion may also disrupt the extremely cold, brittle ice at the surface to produce the chaos regions.

But also: the geography below the glacier will determine what, if anything, will retard the flow of all that ice into the sea.

However, if as a consequence of shortening, the glaciers are also flowing faster, then we would be seeing another (small) contribution to sea level rise.

Thin glaciers would barely flow compared to thick ice sheets if that was the case.

We used Sentinel - 1 satellite data to watch a giant iceberg four times the size of London break free from Antarctica's Larsen - C ice shelf in 2017, and now students can use the same data to measure if new icebergs calve off some of the fastest flowing glaciers in the world!»

If the ice upstream from the calving front warms from whatever it was does that affect the flow rate of the glacier?

If that happened a natural barrier to the flow of ice from glaciers and land - covering ice sheets into the oceans would be removed.

If enough fresh water from melting glaciers flows into the North Atlantic, this would make the seawater less salty and less dense, so that it couldn't sink anymore.

If the glacier thins than there is less friction at the calving front from the fjord walls and the fjord base, leading to greater flow.

Likewise, Rees and Collins (2006) show that if all the Himalayan glaciers were to disappear, there would be about a 33 per cent reduction in annual mean flow in the west compared to the 1990 level, whereas the decline in the east would be only about 4 - 18 per cent (31).

If lava flowing from Eyjafjallajokull melts the glaciers that hold down the top of Katla, then Katla could blow its top, pumping gigantic amounts of ash into the atmosphere.

If the ice shelves were smaller, the glaciers would flow much faster towards the ocean, melting and calving more ice than snowfall inland could replace.
