Has anyone put the pieces together yet and considered how these improvements in understanding ice shelf break - up translate to predicting sea level rise?

Not exact matches

«Many people look at this ice - shelf data and will fit a straight line to the data, but we're looking at all the wiggles that go into that linear fit, and trying to understand the processes causing them,» said Fricker, who was Paolo's PhD adviser at the time the study was conceived.

Understanding what's causing the changes in the ice shelves «puts us a little bit closer to knowing what's going to happen to the grounded ice, which is what will ultimately affect sea - level rise,» Fricker said.

Scientists need to better understand why and how fast the ice shelves are disintegrating so that they can better estimate future sea - level rise.

«Now we want to understand how the ice shelf will react to this calving event.»

A better understanding of how and why the Larsen C crack expanded so quickly could help scientists better predict the future of all Antarctic ice shelves, says Richard Alley, a glaciologist at Penn State.

For six weeks the researchers collected radar data to map changes in ice shelf thickness to understand the processes that contribute to melting at its base.

Now, Bindschadler and other researchers are heading out to fetch some of the first temperature data from under the Pine Island Glacier ice shelf, the outlet of one of the largest and fastest moving glaciers in Antarctica, in hopes of understanding what is happening beneath it.

A study published in February also documented changes in the glacier's flow rate, indicating that little - studied ice shelves are starting to get more attention as scientists» understanding of ice and satellite coverage improves.

Understanding how the ice shelf behaved in the past should help scientists to understand how it will respond to changing climatic and oceanic conditions in the future.

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...

The project aims to improve understanding of snow melt on ice shelves, floating extensions of the massive inland ice sheet which stabilize ice loss, and how melt will impact on ice shelf stability and sea level.

The point of the mission, which involves researchers from the National Oceanography Centre (NOC), the British Antarctic Survey, Oxford University, and other UK - based institutions, is to determine how much glacial ice is drifting into the ocean, and to gain a better understanding of how water is mixing and behaving across the front of the shelf.

One of Antarctica's largest ice shelves is thinning from above and below, helping scientists finally understand just what exactly is causing this rapid ice melt, according to new research.

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)?

# 146: my understanding is that ice shelf breakup does contribute to eustatic sea - level rise, as you say, but only a little, and less so for larger ice shelves (the anchoring is more distant).

At present, numerical models are simply unable to deal with East Antarctica for a variety of reasons including poor model constraints and insufficient understanding of key processes, e.g. circulation of warm water around the periphery and its impact on ice shelf melt.

By studying the factors that cause icebergs to break up, researchers hope to better understand the influences that lead to ice shelf breakup, and to better predict how ice shelves will respond to a warming climate.

This knowledge will help us understand the affects that melting ice shelves have on glacier acceleration and, hence, on sea - level rise.

the sedimentary record (Jakobsson et al., 2011), and our physical understanding (Alley et al., 2008) suggest that beyond some threshold ice - shelf reduction leads to complete loss as the ice shelf calves away, potentially in less than or much less than one year.
