Sentences with phrase «smaller ice shelves»

The collapse of several small ice shelves has caused glaciers to accelerate two - to ninefold and spill more ice into the ocean, raising the sea level.

Meanwhile, fewer than a dozen small ice shelves floating on «warm» waters (seawater only a few degrees above the freezing point) produced half of the total melt water during the same period.

The scientists detected a similar high rate of basal melting under six small ice shelves along East Antarctica, a region not as well known because of a scarcity of measurements.

Not exact matches

This could have significant implications for Antarctica's ice shelves and ice sheets, with previous research showing that even small increases in ocean temperatures can substantially increase melt rates around the Peninsula.

While the rift is only visible in radar images when it is more than 50m wide, by combining pairs of images, SRI allows the impact of very small changes in ice shelf geometry to be detected, and the rift tip to be monitored precisely.

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.

However, it is often overlooked that the major ice shelves in the Ross and Weddell Seas and the many smaller shelves and ice tongues buttressing outlet glaciers are also vulnerable to atmospheric warming.»

All that was left of the massive ice shelf were small icebergs as far as the eye could see.

The Be: Wise project aims to improve understanding of ice - shelf flow dynamics by focusing on the buttressing role of ice rises and pinning points — small offshore mountains which...

For example, how much confidence can we really have in results from ice sheet models, which very likely miss important mechanisms (e.g., due to limited understanding of ocean - ice shelf interactions, calving physics and influence of small - scale topography)?

«Dermot Antoniadesa said: «At this point, it doesn't appear that the shelf ice around Ellesmere Island is any smaller now than it was during the previous period of warming, but because it's still shrinking, it's possible it could become, an «unprecedented» event.

Most of the grounded West Antarctic ice sheet drains into the floating Ross and Ronne - Filchner ice shelves, but a significant fraction also drains into the much smaller Pine Island Glacier.

We've seen this in glaciers after the loss of the Larsen A and B ice shelves (relatively small shelves on the Antarctic Peninsula), and we've seen a similar effect in Greenland, where the floating end of the glacier, and the fjord choked with calved bergs, could apparently perform a similar braking function, now lost for several rapidly - retreating glaciers.

Small changes in global sea level or a rise in ocean temperatures could cause a breakup of the two buttressing ice shelves.

Larsen B glaciers are too small to significantly affect sea level, but the processes that acted on this area could play out on other, bigger ice shelves.

Although only a tiny fraction of the ice shelf melts, the water infiltrates the shelf through small cracks in the ice.

Livescience: When iceberg chunks break off of floating ice shelves, it can serve as dramatic proof of melting — and this traditionally has been considered the main way that these expanses of Antarctic ice become smaller.

A relatively small amount of melting beneath the Amundsen Sea's ice shelf has pushed its grounding line to the top of a sub-glacial hill, from which it is now «rolling down.»

If ice retreats and there is strong upwelling, these copepods could end up on the inner shelf and possibly outcompete smaller zooplankters.

«Apparently, there are weaknesses in the ice shelf — just inland of the rift that caused the 2015 calving — that are resulting in these smaller breaks.»

Antarctica is smaller following the break - up of the Larsen B and Wilkins ice shelves.»

They point out that most of the basal melt come from «small warm cavity ice shelves» and warn about the same stretch near Totten:

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.
