SUMMARY:Geodesy Day - International Webinar on Geodesy
DESCRIPTION:  \n“Every map ever drawn. Every satellite ever launched. Every border ever defined. All rest upon one science… \nGeodesy”\nAbout the Event\nWhat if the science that holds our modern world together remains largely invisible to those who need it the most? Survey of Pakistan (SoP) is determined to change that. \nOn 3 June 2026\, Survey of Pakistan will proudly observe National Geodesy Day in Pakistan – which will become a permanent observance every year. This event on 3 June is a landmark initiative to bring Geodesy out of the shadows and into the spotlight it deserves. In the spirit of the International Union of Geodesy and Geophysics (IUGG) and the International Association of Geodesy (IAG)\, this international webinar unites brilliant minds from across the globe to celebrate\, advance and reimagine the future of geodetic sciences. \nWhy This Moment Matters?\nWe live in an era of climate change\, rapid urbanization\, satellite navigation and digital mapping – all underpinned by the precision of Geodesy. In Pakistan\, however\, the field continues to face institutional challenges\, including limited academic recognition and the absence of dedicated university level degree programs. National Geodesy Day is a strategic initiative to address these gaps\, stimulate scientific discourse and align national efforts with international geodetic standards and priorities. \nObjectives\n\nPromote awareness of Geodesy in Pakistan and its scientific significance within the framework of IUGG and IAG goals\nFacilitate international exchange of knowledge on modern geodetic methods\, technologies and applications\nStrengthen scientific cooperation between Pakistan and the global geodetic community\nTo promote geodetic education and research programs at the national level\nContribute to the advancement of geodetic sciences at regional and global levels in support of IUGG’s mission\n\nWho Should Attend\nThis webinar is open to all experts\, researchers\, academics\, geospatial professionals and students with an interest in geodesy\, surveying\, remote sensing and related disciplines. \nBe Part of Something Significant\nNational Geodesy Day is not a mere webinar\, it is a meaningful step toward strengthening Pakistan’s engagement with the global geodetic community. We invite international experts\, researchers and professionals to join us\, share expertise and help shape Pakistan’s path towards joining more scientifically connected world. \nTo Join the Session\nPlatform:        Zoom \nJoin Link:       https://us06web.zoom.us/j/88311296173 \nMeeting ID:    883 1129 6173 \n“No registration required. Simply click the link on 3 June 2026 and join the session at 11AM (Pakistan Standard Time)” \nHosted by \nSurvey of Pakistan (SoP)\, National Geospatial Agency of Pakistan \nhttps://geodesy.science/wp-content/uploads/EVENT_POSTER_Copyright-JunaidMemon_2026-05-21_b2c478.pdf \nhttps://geodesy.science/wp-content/uploads/EVENT_POSTER_Copyright-SurveyofPakistan_2026-05-21_e7317a.pdf \nhttps://geodesy.science/wp-content/uploads/EVENT_POSTER_Copyright-SurveyofPakistan_2026-05-21_74f73d.pdf \n  \n  \n

SUMMARY:Talks on GIA Seminar
DESCRIPTION:Achraf Koulali (Newcastle University\, UK) and Matt King (University of Tasmania\, Australia) will present: \n“Sensitivity of Antarctic GPS time series to varying surface mass balance loads\, and implications for estimates of Glacial Isostatic Adjustment” \nAntarctic Global Positioning System (GPS) vertical time series exhibit non-linear signals across a wide range of temporal scales\, complicating the interpretation of long-term deformation associated with Glacial Isostatic Adjustment (GIA). One important contributor to these non-linearities is the short-term elastic response of the solid Earth to contemporaneous surface mass balance (SMB) variability. During the first part of this talk\, we will show analysis results of GPS vertical displacement time series from the Transantarctic Mountains (TAM) to quantify the impact of SMB-driven loading on observed crustal motion. SMBL-induced deformation is found to introduce multiyear apparent changes in vertical velocities. After correcting for SMB loading\, most GPS sites exhibit near-zero uplift rates\, with a median velocity of 0.67 mm/yr\, substantially lower than predicted by forward GIA models. We will then discuss these results within the wider context of Antarctica to show the critical role of SMB loading variability in interpreting GPS observations more widely\, with implications for estimates of present-day Antarctic ice mass change. As a second case study\, we will discuss the sensitivity of GPS velocities to SMB variability in a critical sector of East Antarctica\, including in the Denman-Totten glacier region\, suggesting that bedrock motion in that region is broadly of subsidence rather than uplift in contrast to GIA models. Finally\, we will show that modelled SMB variability can be compared with GPS elastic displacements across Antarctica\, as a new form of SMB model validation.

SUMMARY:12 Spanish-Portuguese Assembly of Geodesy & Geophysics
DESCRIPTION:The Spanish-Portuguese Assembly of Geodesy and Geophysics\, which held its first meeting in Almería in 1998\, began meeting every two years\, alternating between the two countries responsible\, Spain and Portugal. Over the course of its sessions\, it has established itself as a research forum in the fields of Geodesy\, Seismology\, Meteorology\, Geomagnetism\, Hydrology\, Oceanography\, Volcanology\, Applied Geophysics\, and Cryospheric Sciences\, as well as a place for meeting and scientific exchange between Spanish and Portuguese researchers through the presentation and discussion of papers in these fields. The COVID-19 period marked the largest gap in the established periodicity\, which we now wish to resume. Thus\, two years after the last meeting\, which took place in Évora in 2024\, the 2026 meeting will be held in Spain. Next June\, from the 16th to the 19th\, Universidad Politécnica de Madrid and its Higher Technical School of Topography\, Geodesy\, and Cartography will host the 12th Spanish-Portuguese Assembly of Geodesy and Geophysics.
