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.
As satellites collect larger and larger amounts of data, engineers and researchers are implementing solutions to manage these huge increases.
As the ice-and-snow rubble known as mélange melts in Antarctica’s ice shelves, rifts can grow and icebergs break off even in the brutal cold of winter.
Are you a coastal planner, a policymaker, or concerned about the future of sea level rise? A new tool allows you to visualize and download the projection data from the Intergovernmental Panel on Climate Change's 6th Assessment Report (AR6).
A new online visualization tool will enable anyone to see what sea levels will look like anywhere in the world in the decades to come.
The pioneering campaign drops probes from a plane into the sea to track how seawater is melting glaciers and lend insight into the future of sea level rise.
