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.
NASA Sea Level Change Team member Robert Kopp uses data on past sea-level rise to improve forecasts of what's to come – and to help coastal planners prepare.
The researchers shared their latest findings, and discussed how to make sea-level science more useful to planners and others preparing for changes on the U.S. coast.
To better predict changes in Antarctica's Thwaites Glacier, sea-level scientists turn their focus to the bedrock beneath.
The Surface Water and Ocean Topography mission will explore how the ocean absorbs atmospheric heat and carbon, moderating global temperatures and climate change.
In a question and answer session, ice sheet researcher Sophie Nowicki, a member of the NASA Sea Level Change Team, discusses a new era in sea-level research.
