Sentences with phrase «ice over a larger region»

This type of analysis may be useful for future applications of using seismic records to track the strength of sea ice over large regions, which has been difficult to determine from satellite observations.»

Scientists say there was no new record set this year because summer temperatures were cooler than in the past two summers and because winds tended to disperse ice over a larger region.

Not exact matches

For their work Maksym and co-investigators Guy Williams from the University of Hobart, Tasmania and Jeremy Wilkinson of the British Antarctic Survey in Cambridge, UK, used a robot known as an autonomous underwater vehicle (AUV) to cruise under ice in three regions near the coast and measure the thickness directly over a much larger area.

The Arctic has transformed over the last five years into a region that's warmer and greener, with larger patches of open water as sea ice recedes.

«As a result of the acceleration of outlet glaciers over large regions, the ice sheets in Greenland and Antarctica are already contributing more and faster to sea level rise than anticipated,» he observed.

«As the Arctic sea - ice cover continues to disappear and the snow cover melts ever earlier over vast regions of Eurasia and North America, it is expected that large - scale circulation patterns throughout the northern hemisphere will become increasingly influenced by Arctic Amplification.»

It is a model of the ocean and ice over a specific domain covering a large part of the Arctic region.

Summer of 2008 shows a large region of less sea ice than normal over the Beaufort Sea compared to 2005 which had less ice cover than normal in the Eastern Siberian Sea and Laptev Sea.

The ongoing loss of ice in a region that is on average not wamer in the latter part of 60 years (1941 - 2000) seems like a good reminder that it does not take a constant yeaer on year increase to cause pronounced natural response over large areas.

If the «boxes» are so large that every land area is considered equal — how are coastal regions and ice - covered areas modelled as they change over the year?

Two main geomorphological forms are commonly found in continuous permafrost regions of Eastern Canada: (i) small, shallow, narrow runnel ponds formed over melting ice wedges where peat slumping occurs, and (ii) more stable, slightly larger and deeper, polygonal ponds, which are naturally linked to the active layer freeze - thaw cycles, and can be colonized by aquatic plants and microbial mats (Fig. 1).

In contrast, SLP has been higher over the Kara sector, which may have contributed to the large current negative anomalies in sea ice concentration in that region of the Arctic.

To a large extent the probability forecasts in Figure 11 resemble the surface air temperature anomaly of the last two months in Figure 7 in the high latitudes, illustrating the persistence of weak climate anomalies over the sea ice and ocean covered regions throughout the summer months.

Behavior of the sea ice over the past winter and the spring and the large positive temperature anomalies in the Arctic (as high as 20 degrees C over large regions in the past winter) suggest that an extent near that of the 2012 minimum may occur again if there is large export of sea ice out to the Atlantic Ocean via the Fram Strait.

The issue, beyond the core data representing but a single geospacial location and thus by itself not representative of the whole (and much larger) region in which it resides, is that the core is near the Greenland summit (in order to get the deepest profile of the ice possible) and therefore at an elevation of over 2 miles above sea level.

Polar Stratospheric Clouds Large, diffuse, ice - particle clouds that form in the stratosphere usually over polar regions.
