New results: the 2020–2022 drought led to ~3 km³/yr water loss around Lake Mead, incl. groundwater depletion. Remote sensing data show up to 8 mm/yr uplift as the crust rebounds. Drought impacts reach far below the surface. doi.org/10.1016/j.ej... #Drought #Groundwater #InSAR #WaterManagement

We wish you well, fellow Sentinel! With a gentle push, #Ariane6 has released the Copernicus Sentinel-1D satellite to orbit where it will begin its amazing life of scientific discoveries. Keep in touch! 📡🛰️

Imagine your city slowly sinking. In India’s megacities, 80M+ people face this reality. New satellite radar research by @nitheshnirmal.bsky.social reveals where the ground is shifting most unevenly. 🌍🏠 #LandSubsidence www.nature.com/articles/s41... @shirzaei.bsky.social @vtgeosciences.bsky.social

Please join me to welcome Ola to the HIRS & EOI labs. He started his PhD studies this semester at the Dept. of Geosciences at Virginia Tech and will be investigating groundwater-induced land subsidence in Virginia's near-coastal areas #InSAR #science @shirzaei.bsky.social @vtgeosciences.bsky.social

On September 12th, I successfully passed my preliminary exams and officially advanced to #PhD candidacy. As part of the process, I proposed my dissertation: "Integration of Remote Sensing Data and #Models for Prediction of #Groundwater Response to Anthropogenic #Drought".

Not just warming but also changes in precipitation may contribute to glacial melting in the Himalayas. See more at attheu.utah.edu/facultystaff... @utah.edu #GraceFO

A new Nature Cities study led by Leonard Ohenhen, PhD, reveals how groundwater extraction contributes to land subsidence in several major U.S. cities. At HIRS Lab, we were proud to support this research with our expertise in groundwater analysis. www.nature.com/articles/s44...

I was interviewed on this study by NASA's press office and provided some comments. The study is very thorough and interesting, recommend reading. Global decline of TWS happens even since many decades (see Fig. 5 of the study), in addition to the abrupt decline of ~2015.
