The Cold Regions Research and Engineering Laboratory Permafrost Tunnel (CRREL Tunnel) in Alaska is one of the best studied Yedoma sequences in North America and is an exceptional site for […]
Climate change driven release of methane (CH4) from polar and sub-polar sediments could accelerate global warming, and tracking CH4 in cold sediments over geological time helps predict future releases. Isotopic […]
Global Mean Ocean Temperature (GMOT) changes are thought to be both an important consequence and a possible cause of Dansgaard–Oeschger (DO) events, a series of abrupt climate changes during the […]
Human activity intensifies the spread of antibiotic resistance genes (ARGs), threatening environmental and public health. Plant metabolite-microbe interactions play a crucial role in mitigating ARGs by shaping the soil environment. […]
Soil ecosystems are shaped by complex interactions between their biological communities, environmental conditions and physicochemical properties. However, higher-trophic soil fauna is often neglected in soil risk assessments. This study utilized […]
Benthic microbial mat communities are key drivers of ecosystem functioning in polar lakes and ponds, forming the base of aquatic food webs and contributing substantially to nutrient cycling. Although Arctic, […]
Sub-Antarctic Macquarie Island is ideally located for reconstructing past variations in Southern Hemisphere westerly wind strength. Diatoms are a valuable palaeolimnological tool on sub-Antarctic islands, providing a means to reconstruct […]
We present high-resolution 10Be concentration and flux records from the Talos Dome ice core (East Antarctica), covering the period from 170 to 270 ka BP, to assess the capacity of Antarctic ice […]
Monitoring reproductive traits in Southern Ocean species is challenging. Males in some channichthyids thicken the epithelium along their anal fins to aid nest construction. This study presents initial evidence that […]
Penguins are emblematic inhabitants of the Antarctic continent and play a significant role in the biogeochemical cycles of the Southern Ocean by transferring essential nutrients to marine ecosystems via guano […]
Southern Hemisphere westerly winds are important drivers of Antarctic and sub-Antarctic environmental change. Short observational wind records prevent us from fully understanding the scope of their variability. Proxy records provide […]
Geomagnetic storms represent a space weather hazard to power transmission networks due to the effects of induced geo-electric fields within the conducting surface of the Earth. These drive electric currents […]
