Paul Tregoning (Australian National University, Canberra, Australia), will present "A tool to assess the accuracy of glacial isostatic adjustment predictions of present-day crustal uplift rates" While there are many global […]
Tracking Mountain Aquifer Storage and Discharge Using Space Geodesy: Using high-precision GNSS surface displacements, this study quantifies groundwater storage changes in the Sierra Nevada and Cascade ranges. Results show long-term depletion due to droughts but rapid recharge during extreme precipitation events, which can restore and sustain groundwater storage and influence regional water supply and ecosystem resilience.
EPOS Days is the flagship annual conference of the European Plate Observing System (EPOS), bringing together researchers, data providers, and infrastructure developers from across Europe to advance collaboration in solid Earth science. The event serves as a key forum to discuss the evolution of EPOS as a pan-European research infrastructure and to showcase progress in […]
We announce a seminar by Wenjin Chen on algorithms and software for efficient gravity forward modeling of hydrological mass changes. The talk reviews methods in Cartesian and spherical systems, comparing accuracy and efficiency of modeling approaches, and highlights trade-offs between realism and computation, with applications to hydrological mass change analysis.
Allie Coonin (Brown University, Providence, USA) and Tamara Pico (University of California, Santa Cruz, USA) will present: "Transient Earth Rheology Temporarily Slows West Antarctic Ice Retreat in Future Climate Projections" […]
We are pleased to announce our third seminar hosted by the IAG Working Group 3.1. Christian Massari will present on hydrologic variability in Europe and beyond using satellites and in situ sensors. The seminar will be held on May 13; further details and the link will be provided later.
Achraf Koulali (Newcastle University, UK) and Matt King (University of Tasmania, Australia) will present: "Sensitivity of Antarctic GPS time series to varying surface mass balance loads, and implications for estimates […]
Here we show that GIA models with realistic 3-D mantle viscosity derived from seismic structures with an effective activation energy of 300–400 kJ/mol and a weak asthenosphere fit paleo-sea level data in North America better than several widely used 1-D GIA models.
We will be hosting three consecutive meetings in Gävle (Sweden) in autumn 2026. Please join us for: Tracking and Investigating Geodynamics and Earth Rotation - TIGER Symposium in Geodesy […]
The Institute of Geosciences (IGEO) and joint IAG-IASPEI sub-commission "Seismo-geodesy" are delighted to invite you to the 21st WEGENER Assembly, which will take place in Tirana, Albania, from October 13–15, […]
A workshop focused on glacial isostatic adjustment (GIA), ice sheets, sea-level change, and associated geodetic and geophysical observational constraints will be held in Dresden, Germany, from 28 May to 2 […]
The Canadian Geophysical Union (CGU) 2028 annual meeting will be held in conjunction with the 38th International Geological Congress (IGC) in Calgary, Canada, from August 12–20, 2028. Under the overarching […]
