Boron Isotope Evidence for Reduced Ventilation of the Deep Arctic Ocean During the Last Glacial Period

Paleoceanography and Paleoclimatology, Volume 41, Issue 9, September 2026.
Abstract Understanding the ventilation of the deep ocean, where most ocean carbon is stored, is essential to understanding how changes to ocean carbon budgets contribute to climate change. In the Arctic Ocean, shifts in ice cover, stratification and temperature are likely to impact carbon sequestration in the ocean interior.

Precession‐Related Variability in North Pacific Deep Water Formation in the Early Eocene: Insights From cGENIE Simulations

Paleoceanography and Paleoclimatology, Volume 41, Issue 9, September 2026.
Abstract Past warmhouse climates differed from the modern ocean circulation regime, with deep‐water formation occurring in regions that are inactive today. Evidence suggests that the North Pacific may have been one such region. The early Eocene, characterized by elevated greenhouse gas concentrations and orbitally paced carbon cycle perturbations ...

Extreme Cold Tolerance in a Calanoid Copepod Embryo From Antarctic Maritime Lakes Helps Explain Expansive Distribution in the Southern Hemisphere

Freshwater Biology, Volume 71, Issue 9, September 2026.
ABSTRACT The Antarctic copepod, Boeckella poppei, occurs in maritime freshwater lakes on sub‐Antarctic islands, Antarctic Islands and the Antarctic continent, but no previous studies assess the thermal tolerance behind this broad geographic distribution.

Non‐Fungi Diversity Present in Soil and Snow Impacted by Anthropogenic Activity in King George Island, Maritime Antarctica Using Metabarcoding Approach

Journal of Eukaryotic Microbiology, Volume 73, Issue 5, September/October 2026.
ABSTRACT The Antarctic Peninsula shows a fast‐rising temperature trend, increasing the risk of colonization by non‐native species, such as the invasive Poa annua. The “cryptic diversity” of largely unknown microscopic propagules in soil and snow poses a significant threat, as traditional morphological surveys are inadequate.
