This six-year NASA mission may not be as simple as switching to tap water or cutting down food waste, but it’s just as important. IceBridge, the largest airborne survey of Earth’s polar ice, will soon provide us the most accurate measure of change over time. The data collected during the mission (which will be completed in 2016) helps scientists keep track of annual changes in thickness of sea ice, glaciers, and ice sheets. Rather then prevent further environmental damage like some of the other campaigns on this list, IceBridge is out to provide concrete data about what to expect from global climate change for years to come.
NASA’s Cryosphere Program
Remote sensing plays a key role in characterizing the world’s major ice sheets due to their size and the scale of change that they undergo. The NASA Cryosphere program has a range of goals, but at present its two highest priorities are understanding:
- Terrestrial ice sheets of Greenland and Antarctica with an emphasis on acquiring data to characterize them and develop predictive models of their behavior and contributions to sea level change.
- Arctic sea ice, and to a lesser extent the Antarctic sea ice, with an emphasis on determining its status and the controls on its extent and thickness.
