David Bekaert is a Radar Scientist at the Radar Science and Engineering Section of the Jet Propulsion Laboratory, where he utilizes Interferometric Synthetic Aperture Radar (InSAR) processing techniques for Earth Science and Geoscience applications including natural hazards and critical infrastructure monitoring. Amongst many applications, time-series InSAR techniques can be used to generate land-based subsidence, one of the two components defining relative sea-level rise. As part of the NASA Sea Level Change Team he is analyzing long-duration SAR time-series to generate regional subsidence maps, helping to identify areas of high vulnerability where land subsidence can exceed the rate of sea-level rise.
A new video series highlights the hard work and passion of scientists and engineers who are helping to get this remarkable new satellite off the ground.
An ongoing sea level change project takes a look at the effects that river discharge has on sea level.
The international Surface Water and Ocean Topography mission will provide high-definition data on the salt- and fresh water on Earth’s surface.
New results show average sea level rise approaching the 1-foot mark for most coastlines of the contiguous U.S. by 2050. The Gulf Coast and Southeast will see the most change.
