Surface Area Of Ice Melting

This seminar series is open to the public and does not require a reservation.

These mass flux solutions provide important observations of the seasonal and inter-annual evolution of the Earth’s land ice as well as overall trends. An increase in meltwater production in a warmer climate could have major consequences on ice-flow rate and mass loss. He studied first electrical engineering and then graduated in natural sciences; with a master degree in 1977 on the climatology of the high Canadian Arctic, and a Ph.

. While climate simulations suggest that ice loss may have impacts on weather patterns well beyond the Arctic, little is known at this time. Community service has included contributions to the National Science Foundation, the National Oceanographic and Atmospheric Administration, and the World Climate Research Programme.

Since its launch in March of 2002, blot hiv test western the soar to success reading program NASA/DLR Gravity Recovery and Climate Experiment (GRACE) mission has been acquiring ultra-precise inter-satellite K-band range and range-rate (KBRR) measurements enabling a direct mapping of static and time-variable gravity. Through the detailed reduction of these GRACE KBRR data, we have computed multi-year time series of surface mass flux for Greenland and Antarctica coastal and interior ice sheet sub-drainage systems as well as the Alaskan glacier systems.

He has lead field expedition to the Greenland ice sheet and other Arctic regions for the past consecutive 33 years to measure the dynamic response of the ice masses under a warming climate; since 1990 he established a climate monitoring network on the Greenland ice sheet with a total of 22 instrument towers transmitting data via satellite link every hour for process studies and model verification.

The rate of ice loss appears to have accelerated in recent years. For more information please contact: Anthony D. Mark Serreze received his BS and MS from the University of Massachusetts, Amherst, in 1982 and 1984, respectively. Recent data show a high correlation between periods of heavy surface melting and increase in glacier velocity. Sea ice extent for September 2007 was the lowest ever recorded, beating the old record set in September 2005 by 23%, an area the size of Texas and California combined.

Konrad Steffen, Professor of Climatology and Remote Sensing and Director of the Cooperative Institute for Research in Environmental Sciences (CIRES), University of Colorado, Boulder, CO Rates of Change in Arctic Sea Ice Cover: Causation, Extent and Implications Since the advent of routine monitoring via satellite in 1979, the area of the Arctic Ocean covered with sea ice, known as ice extent, has declined in all months, most strongly in September.
There is growing recognition that once the ice thins sufficiently, it will become sensitive to a "kick" from natural climate variations that, through feedback mechanisms such as ocean warming in ice free regions due to solar radiation, result in rapid loss of the remaining summer ice cover.

There is strong evidence that reductions in sea ice extent have been accompanied by substantial thinning. Scott is currently a member of the ICESat, GRACE and Jason-2/OSTM science teams and is a member of the American Geophysical Union.
Steffen is the director of the Cooperative Institute for Research in Environmental Sciences (CIRES), the largest research unit at the University of Colorado Boulder Campus. He received a BS in Physics from the University of Maryland and an MS in Physics from the Johns Hopkins University.

Recent Observations on Changes in Polar Land Ice Mass Mass changes of the Earth’s ice sheets and glacier systems are of considerable importance because of their sensitivity to climate change and their contribution to rising sea level. He is a member buying cutting laser machine of the American Geophysical Union and the American Meteorological Society. In addition strong inter-annual variations are observed such as the large mass loss of 2005 resulting from higher surface temperatures and a longer melt season.
Essentially all state-of-the-art global climate models indicate that sea ice extent should be declining over the period of observations, pointing strongly to a role of increased greenhouse gas concentrations. The combination of GRACE high-resolution mass flux observations together with the surface elevation change and surface melt observations is beginning to reveal a detailed understanding of the Earth’s high latitude land ice evolution.

He is now a Senior Research Scientist at the National Snow and Ice Data Center, part of the Cooperative Institute for Research in Environmental Sciences at the University of Colorado. Tentative Topic: The Scale of the Climate/Energy Problem: Treating Symptoms vs. Serreze had authored or co-authored 84 publications in peer-reviewed journals and 8 book chapters.
Steffen serves on a number of national and international committees, most notably he is the co-chair of the World Meteorological Organization (WMO) World Climate Research Program (WCRP) Climate and Cryosphere Program (CliC), the vice president of the IUGG Association of Cryospheric Sciences, the former vice president of the Commission for Snow and Ice for the International Association for Hydrological Sciences, a member of the subcommittee on Earth science to advise the NASA administrator, and he is leading the cryosphere chapter for the for the U. Serreze's research over the past decade has largely turned to understanding these synergistic changes. His early research focused on variability in Arctic weather patterns, and aspects of the Arctic's hydrologic cycle. The Greenland Ice Sheet is losing mass, and that this has most likely been accelerating since the mid 1990s. The likely sensitive regions for future rapid changes in ice volume are those outlet glaciers in Greenland like the Jakobshavn Isbrae, with an over-deepened channel reaching far inland. His all american football jersey dissertation addressed Arctic sea ice circulation and its links with atmospheric variability. The gravity observations show the Greenland ice sheet is losing significant mass at the low elevation coastal regions that is not compensated for by gains in the high elevation interior resulting in an overall rate of loss of 154±10 Gt/yr.
