Observations to support predictions of sea level “CReSIS” contribution toward understanding the term glacial speed

Accurate prediction of sea level is arguably one of the most important societal goals facing the research community. Combining cutting-edge technologies with sustained observations to understand processes and improve numerical models will be required to address the issue of future ice-sheet changes and impacts on global sea level.

Sea Level Rise Modeling with GIS: A Small University’s Contribution To Understanding A Global Dilemma

Earth process modeling and data visualization tools are critical to understanding the processes associated with climate change. One such set of tools is Geographic Information Systems (GIS).

IPY Data Sets at the Alaska Satellite Facility (ASF): RADARSAT-1

Like a canary in a mineshaft, the Earth’s polar regions display the effects of climate change sooner than other places on Earth. International Polar Years (IPY) are specific time frames chosen to gather diverse data sets to examine these effects.

Keeping an Eye On Antarctica

One goal of the International Polar Year is to learn more about the polar regions, but it may not be obvious to most people how we know as much as we do. These areas are remote and harsh, to say nothing of the obvious cold.

Securing the Legacy of IPY

We are in the midst of one of the most exciting international and interdisciplinary science projects that many of us will encounter in our professional careers - the International Polar Year. Scientists in the natural, social, and health sciences are collaborating on some 228 endorsed projects in both the Arctic and Antarctic during a two-year period (March 2007-March 2009) of intense field observations.

Sea Ice Thickness: Hidden Key To Understanding Arctic Change

In the summer of 2007, satellite observations showed that the sea ice coverage of the Arctic Ocean declined to a record low areal extent of only 4.14 km², 23% less than during the previous summer minimum observed in 2005. The shrinkage of the Arctic sea ice cover is generally considered as one of the most striking expressions of the ongoing global climate warming.
