Surveyors, prepare to get your feet wet. Global warming is about to hit you in the job list. By 2050, a majority of U.S. coastal areas are likely to be threatened by 30 or more days of flooding each year. This according to a December report in Earth’s Future, a journal of the American Geophysical Union.

Led by Dr. Attila Komjathy, who received his Ph.D. from the University of New Brunswick in 1997, a team from NASA’s Jet Propulsion Laboratory has demonstrated a technique that has the potential to significantly improve tsunami monitoring and warning. The technique uses data from multiple Global Positioning System receivers on the ground to measure small perturbations in the ionosphere’s electron density caused by a tsunami.
How Ionospheric Observations Might Improve the Global Warning System
Recent investigations have demonstrated that GPS might be an effective tool for improving the tsumani early-warning system through rapid determination of earthquake magnitude using data from GPS networks. A less obvious approach is to use the GPS data to look for the tsunami signature in the ionosphere.
