The Response of the Global Overturning Circulation to Recent and Projected Antarctic Meltwater Changes

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract The Antarctic ice sheet and ice shelves are losing mass and release freshwater to the ocean, affecting the ocean state. The response of ocean circulation to recent and projected increases in Antarctic meltwater is still uncertain, because of uncertainties in meltwater forcing and deficiencies in global ocean and climate models. Here, we use an

Cosmic Dust Flux During the Quaternary: The Record of Large Scoriaceous and Unmelted Micrometeorites From the Transantarctic Mountains Collection

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract We estimate the cosmic dust flux to Earth through the study of rare micrometeorites that preserve part of their precursor features during atmospheric entry heating, namely unmelted and scoriaceous subtypes. Combining high‐precision mass balance measurements, X‐ray computed microtomography and scanning electron microscopy, we studied mass, size

Dynamic Deglacial Evolution of Interior Seaways and Ice Streams in the Weddell Sea Embayment

Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.
Abstract Improving our understanding of Antarctic glacial dynamics is essential for accurately predicting ice sheet behavior and its contribution to global sea level rise under future climate scenarios. The Weddell Sea Embayment, which channels ice from East Antarctica, West Antarctica, and the Antarctic Peninsula into the Filchner‐Ronne Ice Shelf, is ...

A Novel Deep Learning Model for High‐Latitude Ionospheric Convection Using SuperDARN Data

Space Weather, Volume 24, Issue 7, July 2026.
Abstract Plasma convection at high latitudes is a key manifestation of magnetosphere–ionosphere coupling and serves as a critical indicator of space weather conditions. The Super Dual Auroral Radar Network (SuperDARN) provides essential data on ionospheric convection.

Lichen bleaching as a response to long‐term experimental warming in the High Arctic

Functional Ecology, Volume 40, Issue 7, Page 2318-2331, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Lichens are an important component of Arctic ecosystems. Studies have indicated a decline in the abundance of Arctic lichens during recent decades, which is often attributed to competitive pressure from vascular plants.

Wind, waves, wing loading and the flight energetics of giant petrels

Functional Ecology, Volume 40, Issue 7, Page 1979-1993, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Wind is a major factor driving seabird movement and energetics, the effects of which are modulated by morphology. Developments in tagging technology now make it possible to test predictions from aerodynamic theory about the effects of wind on flight performance in free ...
