Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract This study investigates the sensitivity of the oceanic circulation and δ13C ${\delta }^{13}C$ of the dissolved inorganic carbon to ice discharge events from the Laurentide ice sheet (LIS), using an isotope‐enabled and coupled climate–ice sheet model, and observations. The ice discharges are triggered by either reduced friction at the ice sheet‐

Dynamic jamming of iceberg-choked fjords [PDF]
, 2014 We investigate the dynamics of ice mélange by analyzing rapid motion recorded by a time-lapse camera and terrestrial radar during several calving events that occurred at Jakobshavn Isbræ, Greenland. During calving events (1) the kinetic energy of the ice

Earth Surface Processes and Landforms, Volume 51, Issue 2, February 2026.High‐resolution PlanetScope imagery reveals seasonal variations in proglacial lake area are underestimated by ~7% in moderate‐resolution data, while use of a single summer image can underestimate annual maximum area by ~2%. Capturing these seasonal variations provides valuable insights into the factors driving lake dynamics at Fjallsárlón, Iceland ...

Global Biogeochemical Cycles, Volume 40, Issue 2, February 2026.Abstract Increasing freshwater discharge from the cryosphere has the potential to affect mechanisms that regulate the supply of macronutrients to primary producers in the ocean. Although numerous studies have characterized the biogeochemical effects of freshwater discharge from the Greenland Ice Sheet within fjords, it is unclear to what extent these ...

Understanding the physics of iceberg calving is a holy grail problem of glaciology. Progress on this problem has been slow in part because simulating any system with an evolving geometry is a major challenge. We have developed new approaches to simulating glacier flow with evolving termini, including both iceberg calving and the advance and retreat of ...

Iceberg jam floods in Icelandic proglacial rivers: testing the self-organized criticality hypothesis [PDF]
, 2016 In this paper, we describe a fluvial marginal process associated with the formation of iceberg jams in Icelandic proglacial lakes. The floods triggered by the release of these iceberg jams have implications for the geomorphic evolution of the proglacial ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.Abstract During the Eocene‐Oligocene Transition (ca. 34 Ma), the Earth underwent a dramatic decline in atmospheric CO2, global cooling, a deepening of the carbonate compensation depth (CCD), and the formation of a permanent ice sheet on Antarctica. The expansion of Antarctic glaciers eroded the underlying bedrock and increased the weathering flux to ...
