Sedimentology and geochemistry of the recent sediments of the river system on Hurd Peninsula, Livingston Island, Antarctica

open access: yesThe Depositional Record, Volume 12, Issue 4, September 2026.
This study investigates the sedimentology and geochemistry of recent sediments from ephemeral river systems on Hurd Peninsula, Livingston Island, Antarctica. These systems are important for understanding sedimentary and geochemical processes in unique polar environments.

GLOBAL ESTIMATES OF THE IMPACT OF A COLLAPSE OF THE WEST ANTARCTIC ICE SHEET: AN APPLICATION OF FUND [PDF]

open access: yes
The threat of an abrupt and extreme rise in sea level is widely discussed in the media, but little understood in practise, including the likely impacts of such a rise.

Cross‐Range Comparison of Supraglacial Microbial Communities Between Gongga and Gangrigabu Mountains, Southeast Tibetan Plateau

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
We investigated bacterial and fungal community distribution on supraglacial debris from two monsoon‐influenced mountain ranges (Gongga and Gangrigabu) using high‐throughput sequencing. Despite harsh, nitrogen‐limited conditions, diverse microbial taxa were detected, with clear distance–decay patterns and strong glacier‐specificity; heterogeneous ...

Fine‐Scale Population Genomics Reveals Genetic Differentiation in the Brooding Amphipod Cheirimedon femoratus Across the South Shetland Islands, Antarctica

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
Using genotyping‐by‐sequencing‐derived single‐nucleotide polymorphisms, we investigated population connectivity in the Antarctic benthic amphipod Cheirimedon femoratus across the South Shetland Islands. Despite the limited dispersal potential of this brooding species, populations showed substantial genetic connectivity, likely maintained through ...

Variability in Overwinter Antarctic Krill Transport Pathways and Connectivity in the South‐West Atlantic Sector of the Southern Ocean

open access: yesGlobal Change Biology Communications, Volume 1, Issue 3, September 2026.
Our study demonstrates that particles transported within sea ice are advected over substantially larger distances compared with those transported solely by ocean currents, indicating that sea ice dynamics play a dominant role in enhancing long‐range particle dispersal in the Southern Ocean relative to ocean‐only transport.

Rethinking Plasticity in Sponges

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 6, Page 431-446, September 2026.
This systematic review critiques the conceptual confusion caused by the indiscriminate use of “plasticity” in Porifera literature, revealing that researchers often overlook genetic variability and fail to distinguish between real‐time environmental responses and natural selection.

Antarctic sea ice : a seasonal perspective

open access: yes
Saisonnalité de la banquise antarctique La banquise antarctique a subi une réduction brutale en 2016, après plus de quatre décennies d'une lente augmentation. Une telle évolution pourrait avoir de larges conséquences, compte tenu de l'importance de la banquise antarctique pour le climat, l'océan et l'écosystème marin polaire local ...

Composition and Provenance of Victoria Group Sandstones in Southern North Victoria Land, Antarctica

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.
Three distinct source areas contributed to sandstones of the Victoria Group within the Transantarctic Basin in southern North Victoria Land. During the Permian, quartzose sandstones were derived from erosion of the local Ross Orogen, likely from an uplifted swell in the area of today's Ross Sea, the Ross High.
