Latest Model Indicates Ice Caps Can Recover

By Henry Workman Marine Science Today Writer Today, the body of evidence that points towards the climate change driven melting of the polar ice caps is substantial, and continues to grow.  The environmental implications of this process have been consistently shown to be severe, and the problems associated with the subsequent rise in sea levels [...]

Antarctica sea ice - Data collected during NASA's Operation Ice Bridge with airborne radar and laser instruments will provide information about surface elevation, snow depth and ice thickness. Other primary targets include ice sheets and glaciers.  -  Image Credit: National Snow and Ice Data Center

NASA’s Flights Over Antarctic Continent Bridge Satellite Gap

NASA is currently conducting Operation Ice Bridge, a six-year campaign of annual flights to each of Earth’s polar regions designed to help scientists bridge the gap between NASA’s Ice, Cloud and Land Elevation Satellite (ICESat) — which is operating the last of its three lasers — and ICESat-II, scheduled to launch in 2014 by providing the needed data collected by researchers on board the DC-8, a 157-foot-long airborne laboratory and the largest aircraft in NASA’s airborne science fleet that accommodates many instruments.

New Satellite Data Shows Ocean Plants Health

A study funded by NASA allowed researchers to conduct the first global analysis of the health and productivity of ocean plants.

Melting Ice Is Creating Climate and Ocean Condition Changes

New studies show global temperature is increasing and polar ice is melting more rapidly than expected, accelerating climate and ocean condition changes.
