Antarctic Meltwater‐Stratification Feedback Is Less Pronounced Under High Climate Forcing

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Several studies have shown sub‐surface warming in the Southern Ocean via an increase in meltwater flux from the Antarctic Ice Sheet (AIS), which can lead to a positive feedback through enhanced basal melting. In this study, we investigate how the feedback strength is related to the prevailing climate in a coupled climate–ice‐sheet model.

Airborne Radar Reveals Area‐Wide Decadal Increase of Surface Mass Balance on the Plateau in Dronning Maud Land, East Antarctica

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Projections of Antarctica's sea‐level contribution depend on future changes in surface mass balance (SMB), yet it remains uncertain whether climate change has already impacted SMB on the East Antarctic Plateau, given diverging trends in prior studies.

Nitrogen Stable Isotopes Track Ammonia Emission Sources and Ammonium Aerosol Formation Processes in the Marine Boundary Layer

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract We measured the nitrogen isotopic composition of surface seawater and aerosol ammonium in the Weddell Sea region of the Southern Ocean to investigate the natural atmospheric cycle of marine ammonia emissions and aerosol ammonium formation in a region not overwhelmed by anthropogenic emissions.

Self‐Lofting Drives Tropospheric and Stratospheric Transport of Australian Wildfire Smoke to Antarctic Ice

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The 2019–2020 Australian New Year (ANY) wildfires injected vast amounts of aerosols and trace gases into the atmosphere. Previous studies focused on pyrocumulonimbus (pyroCb) activities that inject smoke directly into the upper troposphere. Our study shows that extensive aerosol plumes emitted into the lower troposphere during ANY wildfires ...

Quantifying Under‐Ice Phytoplankton Blooms in the Changing Arctic and Southern Oceans

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Historically, polar marine phytoplankton were thought to primarily grow after the seasonal breakup of sea ice, when there is plentiful light available in the surface ocean. However, observations of substantial productivity under sea ice has called this assumption into question.

Observed Drivers of Rapid Sea‐Ice Melt Events in the Arctic During Summer

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Rapid, episodic sea‐ice loss during the summer is commonly attributed to strong winds from Arctic storms, but the physical relationship between winds and ice melt remains poorly understood. Therefore, we use observations of the air‐sea‐ice interface from autonomous buoys deployed throughout the Arctic over the last two decades to examine the ...
