Radiocarbon Dating of Hadal Water Replacement in the Puerto Rico Trench
GENERAL TOPICS IN PHYSICAL AND GEOLOGICAL OCEANOGRAPHY POSTER
ocean sciences | 14 december 2023
Steven D'Hondt, David Casagrande, Alan R. Gagnon, ...
We recently generated the first radiocarbon profile for seawater in and above a deep-sea trench. The profile was made possible by intensive sampling d...

Subsidence in Coastal Cities Throughout the World Observed by InSAR
GEOPHYSICAL RESEARCH LETTERS
30 march 2022
Pei-Chin Wu, Meng (Matt) Wei, Steven D'Hondt
We measured subsidence rates in 99 coastal cities around the world between 2015 and 2020 using the PS Interferometric Synthetic Aperture Radar met...
Using InSAR to detect coastal urban subsidence around the world
RECENT ADVANCES IN SAR AND INSAR DATA PROCESSING, BIG DATA ANALYSIS, AND EARTH SCIENCE APPLICATIONS IV POSTER
geodesy | 16 december 2021
Pei-Chin Wu, Meng (Matt) Wei, Steven D'Hondt
Our InSAR results indicate that land is subsiding faster than sea-level is rising in many coastal cities throughout the world. If subsidence continues...
