SUMMARY:Talks on GIA Seminar
DESCRIPTION:Jacky Austermann and Ben Stoker\, both at Columbia University\, Palisades\, USA\, will present \nProglacial Lakes as Windows into GIA and Drivers of Ice-Sheet and Climate Chang \nPart I (Jacky):\nProglacial lakes are lakes that form around the margins of ice sheets. Both talks will focus on proglacial lakes around the Laurentide Ice Sheet. In the first part\, we will present simulations of the Last Glacial Cycle where we included self-consistently evolving proglacial lakes in a glacial isostatic adjustment (GIA) model. We found that proglacial lakes are up to five times bigger (by volume) during the deglaciation compared to glaciation for the same ice position and size\, which is a result of the differences in the position and size of the peripheral bulge. Proglacial lake depth affects ice dynamics at the grounding line and we show that indeed at certain times during the deglaciation\, Laurentide ice-margin retreat rate is positively correlated with proglacial lake presence. This supports an early hypothesis that GIA – by shaping proglacial lakes – plays an active role in accelerating collapse of the deglacial Laurentide Ice Sheet. \nPart II (Ben):\nThe new NADI-1 reconstruction of the Laurentide Ice Sheet margin chronology allows us to update the GIA-proglacial lakes model to reconstruct proglacial lake evolution more accurately. Despite widespread evidence of glacial lake extent and dynamics at the basin-scale\, continental-scale compilations of this evidence is outdated and does not take advantage of the advances in surficial mapping. Here we will present a new effort to compile paleo lake shorelines across North America. We find that our lake compilation enhances existing databases by orders of magnitude along the western margin and therefore increases important constraints on GIA in the continental interior. We have compared our lake database to an ensemble of the GIA-proglacial lakes models and will show the new constraints that this data-model comparison puts on both ice reconstruction and solid Earth properties. Further\, we have used our best-fitting simulations to calculate freshwater routing over the deglaciation\, providing new\, data calibrated model predictions on where and how much freshwater forcing might have affected ocean circulation.

SUMMARY:2028 Glacial Isostatic Adjustment Workshop
DESCRIPTION: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 June 2028. This will be a follow-on workshop in a series of similar events. The last GIA Workshop took place in Sidney\, BC\, Canada\, in 2025 (cf. https://polenet.org/2025-gia-workshop/). Detailed information will be published in due time.

SUMMARY:CGU 2028-IGC2028 First Circular
DESCRIPTION: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 theme “Geosciences for Humanity\,” this joint event serves as a premier global forum for advancing Earth science research and its societal applications. \nThe CGU program specifically anchors the Geomatics and Geodesy theme (Category V\, Group AJ)\, focusing on the critical role of geodetic infrastructure in monitoring a changing planet. \nKey Scientific Focus Areas: \n\nReference Frames & Gravity: Modernizing global and regional spatial frameworks.\nGeodynamics: Solid Earth processes\, active tectonics\, and natural hazard assessment.\nClimate & Cryosphere: Glacial Isostatic Adjustment (GIA) and sea-level change.\nSpace Geodesy: Advanced GNSS applications\, reflectometry\, and Earth observation.\nEnvironmental Monitoring: Hydrology and anthropogenic impact tracking.\n\nSubmission Deadline: Session proposals must be submitted via the Scientific Program Portal by March 2027. \nThe first circular is available here \n
