Abstract Extreme winter warming events over the Antarctic Peninsula (AP) have potential impacts on ice‐shelf stability, but their mechanisms and teleconnections remain poorly studied. Using multi‐station observations, we report several warm extremes during May–June 2026, with early–June temperatures exceeding 0°C and peak anomalies reaching +22.32°C ...

Assessing the catastrophic break-up of Briksdalsbreen, Norway, associated with rapid climate change
Recent research has raised concerns about the potential influence of rapid climate change on the stability of major ice sheets. The behaviour of glaciers is determined largely by the processes and conditions operating at their base.

The Chaos Beneath a Glacier’s Calving Front
For the first time, researchers have captured continuous data on the abrupt changes and activities happening at a glacier’s calving front.

Glacier dynamics near the calving front of Bowdoin Glacier, northwestern Greenland [PDF]
AbstractTo better understand recent rapid recession of marine-terminating glaciers in Greenland, we performed satellite and field observations near the calving front of Bowdoin Glacier, a 3 km wide outlet glacier in northwestern Greenland. Satellite data revealed a clear transition to a rapidly retreating phase in 2008 from a relatively stable glacier ...

Hidden subsurface suspended sediment export from Greenland's marine‐terminating glaciers
Abstract Runoff and calved ice volumes from the Greenland Ice Sheet are well constrained, but quantifying the associated suspended sediment flux remains challenging. Here we present near‐terminus observations from three glacierized fjords in southeast Greenland, combining full‐depth turbidity profiles and current velocity from summer 2024 to evaluate ...

The integrated ice sheet response to stochastic iceberg calving
Iceberg calving is a major source of ice loss from the Antarctic and Greenland ice sheets. However, it is still one of the most poorly understood aspects of ice sheet dynamics, in part due to its variability at a wide range of spatial and temporal scales.

Abstract Nitrogen uptake by phytoplankton influences Southern Ocean productivity and carbon export, but how source‐resolved meltwater is associated with nitrate and ammonium use remains unclear. Here, 15N tracer incubations and a δ18O‐salinity mixing model were combined to examine nitrogen uptake in the early‐summer Cosmonaut Sea.

Step-wise changes in glacier flow speed coincide with calving and glacial earthquakes at Helheim Glacier, Greenland [PDF]
Geodetic observations show several large, sudden increases in flow speed at Helheim Glacier, one of Greenland's largest outlet glaciers, during summer, 2007.

Tidewater glacier response to individual calving events
AbstractTidewater glaciers have been observed to experience instantaneous, stepwise increases in velocity during iceberg-calving events due to a loss of resistive stresses. These changes in stress can potentially impact tidewater glacier stability by promoting additional calving and affecting the viscous delivery of ice to the terminus.

Abstract On its way south to the North Atlantic Ocean, Arctic water of both Atlantic and Pacific origin is modified by sea ice and glacial melt, meteoric water (MW), and continental shelves. In the eastern Canadian Arctic, this modification occurs during transit through Nares Strait, Jones Sound, Barrow Strait, Lancaster Sound, and southward through ...
