Sentences with phrase «of ice volume»

These changes are dominated by the amount of ice volume change.

This can cause data estimates to snowball, and it might account for the apparent accellerating decline of the ice volume time series.

It appears that the warming seas around Antarctica are causing an increase in snowfall over the ice - cap, and the increased snowfall on top roughly cancels out the decrease of ice volume caused by erosion at the edges.

Glacial periods during the 100,000 - year cycles have been characterised by a very slow build - up of ice which took thousands of years, the result of ice volume responding to orbital change far more slowly than the ocean temperatures reacted.

Using new data from CryoSat - 2 validated with in situ data, they generate estimates of ice volume for the winters of 2010/11 and 2011/12 and compare these data with current estimates from the University of Washington team of sea ice hindcasts (PIOMAS) and earlier (2003 — 8) estimates from the ICESat mission.

The transient response of ice volume to orbital forcing during the warm late Pliocene.

The number of cryospheric elements now routinely monitored from space is growing, and current satellites are now addressing one of the more challenging elements, variability of ice volume.

Estimates of ice volume in northern hemisphere permafrost range from 1.1 to 3.7 x1013 m3 (Zhang et al., 1999), equivalent to 0.03 to 0.10 m of global - average sea level.

Soon we'll know more: Cryosat, already in orbit, will soon finish its shakedown period and begin the first series of regular satellite reports of ice volume.

«Our new method not only provides an estimate of the ice volume, but allows calculating local ice thickness on a fine grid for each of the 200,000 glaciers worldwide,» he said.

«While everyone only looks at ice extent or area, because it is so easy to do with satellites, we study ice thickness, which is important to assess overall changes of ice volume, and helps to understand why and where the ice is most vulnerable to summer melt,» says lead researcher York Professor Christian Haas, the Canada Research Chair for Arctic Sea Ice Geophysics.

«The climate has always changed and it always will — there is nothing unusual about the modern magnitudes or rates of change of temperature, of ice volume, of sea level or of extreme weather events,» Mr Carter added.
