Accelerating Ice Loss From Peripheral Glaciers in North Greenland by Shfaqat A. Khan, William Colgan, Thomas A. Neumann, Michiel R. van denBroeke, Kelly M. Brunt, Brice Noël, Jonathan L. Bamber, Javed Hassan, Anders A. Bjørk

“…While their total area of Greenland ice cover is relatively small (4%), their mass loss is disproportionally large compared to the Greenland ice sheet. Satellite altimetry from Ice, Cloud, and land Elevation Satellite (ICESat) and ICESat‐2 shows that mass loss from Greenland's peripheral glaciers increased from 27.2 ± 6.2 Gt/yr (February 2003–October 2009) to 42.3 ± 6.2 Gt/yr (October 2018–December 2021). …”

Assessing the effects of fjord geometry on Greenland tidewater glacier stability by Elizabeth Fischer, Andy Aschwanden

On the factors and the degree of their effect on subglacial melt and changes in the state of Antarctic subglacial lakes by Alina Boronina, Sergey Popov, Gang Qiao

“…It is the heat flux that is responsible for the transition of most Antarctic lakes from a stable state to an active one (except for the ice stream regions). In areas where the ice sheet is thinner than 1,500 m, air temperature is the second most important factor affecting subglacial conditions. …”

Interannual Variability and Trends in Extreme Precipitation in Dronning Maud Land, East Antarctica by Lejiang Yu, Shiyuan Zhong, Svetlana Jagovkina, Cuijuan Sui, Bo Sun

“…These findings shed light on how large-scale atmospheric circulation and tropical-extratropical teleconnections shape Antarctic precipitation patterns, with potential implications for ice sheet stability and regional climate variability.…”

Theoretical stability of ice shelf basal crevasses with a vertical temperature profile by Niall Bennet Coffey, Ching-Yao Lai, Yongji Wang, W. Roger Buck, Trystan Surawy-Stepney, Anna Elizabeth Hogg

“…Using HFB instead of Zero Stress for cracks in an ice-sheet model would substantially enlarge the predicted fracture depth, reduce the threshold rifting stress and potentially increase the projected rate of ice shelf mass loss.…”

Lacustrine sedimentation patterns at the Northern Antarctic Peninsula and surroundings as a response to late Holocene and Modern Climate changes by Heitor Evangelista, Sergei Verkulich, Bulat Mavlyudov, Mariza P. Souza Echer, Marcus Vinicius Licinio, Gerd Dercon, Felipe García-Rodríguez, Arthur A. Neto, Stephanie Kusch, Rodrigo C. Abuchacra, Anna B.J. Oaquim, Sérgio J. Gonçalves, Zinaida Pushina, Marília H Shimizu, Maria Heiling, Johanna Slaets, Christian Resch, Alejandra Castillo, Roman Gruber

“…Abstract The Northern Antarctic Peninsula (NAP) and the West Antarctic Ice Sheet (WAIS) are likely to respond rapidly to climate changes by increasing the collapse of peripheral ice shelves and the number of days above 0 °C. …”

Radar internal reflection horizons from multisystem data reflect ice dynamic and surface accumulation history along the Princess Ragnhild Coast, Dronning Maud Land, East Antarctica by Inka Koch, Reinhard Drews, Steven Franke, Daniela Jansen, Falk Marius Oraschewski, Leah Sophie Muhle, Vjeran Višnjević, Kenichi Matsuoka, Frank Pattyn, Olaf Eisen

“…Ice shelves, which regulate ice flow from the Antarctic ice sheet towards the ocean, are shaped by spatiotemporal patterns of surface accumulation, surface/basal melt and ice dynamics. …”

New glacier thickness and bed topography maps for Svalbard by W. van Pelt, T. Frank

“…Specifically, we model large glaciers with the Parallel Ice Sheet Model (PISM) at 500 m resolution, while we resolve smaller mountain glaciers at 100 m resolution using the physics-informed deep-learning-based Instructed Glacier Model (IGM). …”

Environment of European Last Mammoths: Reconstructing the Landcover of the Eastern Baltic Area at the Pleistocene/Holocene Transition by Ivan Krivokorin, Anneli Poska, Jüri Vassiljev, Siim Veski, Leeli Amon

“…Our results indicate that these last mammoths utilised the open landcover of the Eastern Baltic, which developed as the continental ice sheet retreated during the termination of the last glaciation. …”

Recent change in surface mass-balance trends of glaciers on James Ross Island, north-eastern Antarctic Peninsula by Zbyněk Engel, Kamil Láska, Jana Smolíková, Jan Kavan

“…Glaciers cover 132 900 km2 around the Antarctic Ice Sheet, but few are subject to annual mass-balance measurements. …”

Mechanisms for upstream migration of firn aquifer drainage: preliminary observations from Helheim Glacier, Greenland by Jessica Z. Mejia, Kristin Poinar, Colin R. Meyer, Aleah N. Sommers, Winnie Chu

“…Surface meltwater can influence subglacial hydrology and ice dynamics if it reaches ice sheet's base. Firn aquifers store meltwater and drain into wide crevasses marking the aquifer's downstream boundary, indicating water from firn aquifers can drive hydrofracture to establish surface-to-bed hydraulic connections at inland locations. …”

Ocean warming, icebergs, and productivity in the Gulf of Alaska during the Last Interglacial by Maria Luisa Sánchez Montes, Maria Luisa Sánchez Montes, Erin L. McClymont, Hirofumi Asahi, Joseph Stoner, Christopher M. Moy, Sophie Gleghorn, Jerry M. Lloyd

“…The Pacific Ocean is an important region for carbon storage, yet the past ocean–climate interactions are relatively underexplored in explaining glacial/interglacial climate variability during the late Pleistocene re-expansion of the Cordilleran Ice Sheet (CIS). We analysed marine sediment samples from IODP 341 Expedition Site U1418 in the Gulf of Alaska (GOA) using marine and terrestrial biomarkers to study the periodicity of glacial–interglacial cycles over the last 500 thousand years and reconstruct the North Pacific oceanography and marine productivity. …”

“…Finally, despite similar findings between the proxy and model data, notable differences persist between both interglacials – emphasizing the necessity for different Antarctic ice sheet configurations to be employed and more robust paleoclimate data to enhance climate model performance close to the Antarctic continental margin.…”
