Seascape genomics reveals high genetic diversity and apparent panmixia in endemic Southern Ocean phytoplankton

Limnology and Oceanography Letters, Volume 11, Issue 6, November 2026.
Abstract The adaptive potential and resilience of cold‐adapted phytoplankton to climate change have the potential to impact polar marine food webs and global biogeochemical cycles. Two central but poorly constrained facets of adaptive potential in polar phytoplankton are standing genetic diversity and its spatial structure. Here, we partially sequenced

The 2 May 2025 Mw 7.4 Drake Passage Earthquake: Insights Into Tectonics at the Shackleton Fracture Zone–Chilean Trench Transition

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract On 2 May 2025, an Mw 7.4 earthquake occurred ∼120 km off the southern tip of Tierra del Fuego, at the transition of the Shackleton Fracture Zone and the Chile Trench. This event exhibits reverse‐faulting mechanisms with relatively steeply dipping planes and is the largest recorded along this complex plate boundary.

Reassessing Methanesulfonic Acid as a Sea Ice Proxy: An Example From the Weddell Sea Sector

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Antarctic sea ice has declined since 2015, but placing this trend in a longer‐term context remains challenging. Ice core methanesulfonic acid (MSA) offers a potential record of sea ice variability beyond the instrumental period, yet its applicability in sectors including the Weddell Sea remains unclear.

Antarctic Peninsula mesoscale cyclone variability and climatic impacts influenced by the SAM [PDF]

, 2008
The frequency of mesoscale cyclones in the Western Antarctic Peninsula (WAP) region during 1991-94 is correlated with the Southern Hemisphere Annular Mode (SAM) index, most strongly during winter and spring.

Long-term spatiotemporal variability and driving mechanisms of tropospheric total column water vapor over Antarctica based on radiosonde, GNSS, and reanalysis data

Geo-spatial Information Science
Total column water vapor (TCWV) is a crucial indicator of atmospheric processes in the troposphere and a key driver of climate change. However, the severe environmental conditions in Antarctica constrain research on spatiotemporal variability and its ...

Interpreting Air Temperature Trends Across the Antarctic Peninsula Between 1979 and 2025

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The near‐surface temperature of the Antarctic Peninsula is marked by strong spatio‐temporal variability. In situ observations are scarce and therefore have limited spatial coverage. Furthermore, ERA‐5 reanalysis does not have a sufficient spatial resolution to capture the steep topography and other climate gradients of the peninsula.

Shipborne Measurements of Mineral Dust and Black Carbon Aerosols Over the Southern Ocean in the Austral Summer

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Atmospheric mineral dust and black carbon (BC) aerosols play important roles in the Earth's climate system, yet direct observations over the Southern Ocean (SO) are scarce. In this study, we present the characteristics of airborne water‐insoluble particles (WIPs) collected during a cruise of the R/V Shirase in the Australian and Indian sectors

State of Balance of the Ice Sheet in the Antarctic Peninsula [PDF]

Annals of Glaciology, 1982
Data from ice rises on the east coast of the Antarctic Peninsula can be interpreted as showing that the ice is thinning at rates of up 0.5 m a−1. However, a level line between two nunataks in Palmer Land showed no change in surface elevation over a period of 5 a.
