Disentangling the oceanic drivers behind the post-2000 retreat of Sermeq Kujalleq, Greenland (Jakobshavn Isbræ) [PDF]

The Cryosphere
Ocean temperatures have warmed in the fjords surrounding the Greenland Ice Sheet, causing increased melt along their ice fronts and rapid glacier retreat and contributing to rising global sea levels.

Glacial Ice‐Front Calving: Internal Wave Generation and Melting

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Small, frequent calving events dominate the behavior of most Arctic marine‐terminating glaciers, yet their oceanographic impacts remain largely unquantified. We present the first direct observations of internal waves generated by modest ice‐fall calving at Kronebreen, Svalbard. High‐resolution current meter and microstructure measurements show

Ice‐Sheet–Ocean Interactions and the Reversibility of a Regime Shift Beneath Filchner‐Ronne Ice Shelf

Journal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract Future atmospheric warming could cause an abrupt increase in ocean temperature beneath the Filchner–Ronne Ice Shelf, Antarctica, from −2.2°C to more than 0°C in a few decades. In simulations, such a transition leads to a twenty‐fold increase in sub‐shelf melt rates, driving a retreat of the ice sheet.

The Decline of a Caldera‐Filling Glacier at Volcán Sollipulli, Chile

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Southern Andean glaciers have undergone fast retreat in recent decades. This results in reduced freshwater storage, contribution to sea‐level rise, and locally to the formation of glacial lakes, that may pose the risk of glacial lake outburst floods (GLOFs).

Patterns in glacial-earthquake activity around Greenland, 2011–13

Journal of Glaciology, 2017
Glacial earthquakes are caused by large iceberg calving events, which are an important mechanism for mass loss from the Greenland ice sheet. The number of glacial earthquakes in Greenland has increased sixfold over the past two decades.

Role of Mid‐ and High‐Latitude, Southern Hemisphere Processes for Ushering in the Middle Pleistocene Transition

Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract Glacial‐interglacial cycles increased in length from about 41 to 100 thousand years during the Middle Pleistocene Transition (MPT) about 1.5 to 0.8 million years ago. This took place in step with strong global cooling after several million years of weaker cooling.

The Influence of Sea Ice and Ice Mélange on Outlet Glacier Dynamics in the Arctic and Antarctic: Recent Progress and Future Challenges

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Sea ice is situated close to the termini of many outlet glaciers in the Arctic and Antarctic and has the potential to influence their dynamics and, therefore, their contribution to sea level rise. However, the nature, prevalence, and ice‐dynamic significance of sea ice‐glacier interactions remains subject to several open questions.

Juvenile predation overwhelms nutritional effects on female ungulate fat reserves in a high‐predation system

Functional Ecology, Volume 40, Issue 6, Page 1578-1586, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ungulate body fat reserves reflect the nutritional environment, often serving as a useful indicator of bottom‐up resource availability. However, body fat reserves also integrate energetic costs associated with avoiding predation risk and reproductive effort, and it is ...

Modelled dynamics of floating and grounded icebergs, with application to the Amundsen Sea [PDF]

The Cryosphere
Icebergs that ground on the submarine Bear Ridge in the Amundsen Sea are known to block the drift of sea ice, playing a crucial role in maintaining shelf sea ocean conditions.
