Dear colleague,
Since more than 40 years ago, WEGENER has brought together geoscientists who want to collaborate on the application of space and terrestrial geodetic techniques to the study of geodynamics in the Alpine–Mediterranean plate boundary region.
During the past decade, WEGENER has broadened its scopes beyond the Mediterranean and Geodesy. This led to the creation of a new Seismo-geodesy sub-commission, jointly supported by the International Association of Geodesy (IAG) and International Association of Seismology and Physics of the Earth’s Interior (IASPEI).
WEGENER, through meetings organized every two years in and around the Mediterranean is now an important component, offering a space for collaborative discussion and presentation of research.
The 20th WEGENER Assembly 2023 will be organized by the National Office of Mines (ONM which is the Geological Survey of Tunisia) from 24 to 27 October 2023 in Sousse, Tunisia. The ONM has shown a substantial interest in the processing of GNSS data and the geodynamic study of Tunisia since 2019.

For the past 12 months, global energy markets have been roiled by geopolitical conflict and instability, rising post-COVID demand, and efforts by many developed countries to speed their transition to a less carbon-intensive energy matrix. The United States has not been immune from these phenomena, nor has it been passive in its response. The enormous energy potential of the US, in both hydrocarbons and renewable energy, place the country in a privileged position to respond to turmoil in energy markets and to put forward a viable vision of the future.
Join us on March 29 for a conversation with Angelina LaRose, Assistant Administrator of the Energy Information Administration focused on the outlook for US and global energy markets in the face of the transition. As Assistant Administrator, Ms. LaRose directs the EIA’s energy modeling program, which supports the EIA’s forecasts and projections. Angelina also manages the topical analyses that EIA produces that span a range of fuels and activities.
Speakers
- Angelina LaRose - Assistant Administrator for Energy Analysis, U.S. Energy Information Administration
- Duncan Wood - Vice President for Strategy & New Initiatives; Senior Advisor to the Mexican Institute

The Arctic, dominated by continuous and discontinuous permafrost, which occupies about 22 million km2 of exposed NH land areas, has been warming much faster than the rest of the world, commonly known as Arctic amplification. The active layer above the permafrost is a seasonally frozen ground above the permafrost table that is frozen in winter and thaws in summer. In the 2017 Arctic Boreal Vulnerability Experiment (ABoVE) airborne campaign, airborne L- and P- band SAR was used to acquire a dataset that provides estimates of seasonal active layer thickness, ALT and the vertical soil moisture profile for 51 sites across the ABoVE domain, including 39 sites in Alaska and 12 sites in Northwest Canada. We modeled the ALT of ABoVE dataset using thawing degree day (TDD) taken from the 2-m air temperature of ERA5 dataset, using ALT = K√TDD modified from the Stefan’s Equation, where K is calibrated for the 51 swaths with an excellent fit, R2 = 0.9783. We also obtained an excellent fit between ALT and the surface ground temperature of ERA5 at 3 levels, with R2 = 0.9719. Therefore, ALT can be reasonably estimated using either TDD based on 2-m air temperature, or near surface soil temperature. Arctic structures are vulnerable to the settlement of frozen ground caused by thawing of permafrost. The SSP (Shared-Social Economic Pathway) climate change scenarios, SSP 1-2.6, SSP 2-4.5 and SSP 5-8.5 of 7 global climate models (GCMs) statistically downscaled to about 25-km resolutions are used to project climate change impact to the ALT of the 51 swatches of the ABoVE dataset. Assuming ALT= K√TDD, the projected warming of UKESM1-0-LL GCM resulted in the largest projected ALT for the study site, up to about 0.7 m in 2080s under SSP5-8.5 climate scenarios. Given the mean observed ALT of the study site is about 0.48 m, it means that ALT of the 51 study sites is projected to increase by 0.074m to 0.217m, or between 15 and 45% by 2080s, which is expected to impact the Arctic infrastructure.

Where: Inuvik Northwestern Territories Canada
The Arctic Development Expo welcomes all researchers, Indigenous leaders, circumpolar Governments, scientists, industry experts and passionate individuals to join us in 2023.
The Arctic Development Expo takes place in Inuvik, Northwest Territories, Canada as we strive to make knowledgeable decisions to enhance circumpolar life and create innovative solutions for our northern realities. We look to develop the Arctic through sustainable means and will do so by concentrating on the following four themes: Natural & Renewable Resources, Climate and Energy Innovations, Indigenous Leadership and Circumpolar Governance and Knowledge Economy.
