Josh Willis, Project Scientist, JPL,
  • Public Event

Global sea level rise is one of the major environmental challenges of the 21st century. As lead scientist for multiple NASA JPL projects, Josh Willis and team are addressing this urgent problem from above and below. The Jason and Sentinel-6 satellites are measuring sea levels from space, and Oceans Melting Greenland, an airborne mission, is probing the island's warming coastal waters to help better predict the rising seas of the future. In this lecture, Willis will discuss how these missions will provide revolutionary data for modeling ocean and ice interactions and lead to improved estimates of global sea level rise.

This lecture will be presented in a hybrid format, allowing for both virtual viewers and in-person attendees. No advanced registration is required for either format.

About the Series

Since 1922, The Earnest C. Watson Lecture Series has brought Caltech's most innovative scientific research to the public. The series is named for Earnest C. Watson, a professor of physics at Caltech from 1919 until 1959. Spotlighting a small selection of the pioneering research Caltech's faculty is currently conducting, the Watson Lectures are geared toward a general audience, as part of the Institute's ongoing commitment to benefiting the local community through education and outreach.

Many past Watson Lectures are available in a playlist on YouTube.
