The total amount of methane (CH4) released from the global ocean is uncertain. It is important that this component of the global CH4 budget is better constrained, as a more […]
In the Southern Ocean, reconstructions of past sea ice conditions remain challenging because of limited proxy and calibration approaches. Sedimentary DNA can complement the available proxies for reconstructing past sea […]
Natural disturbance events are expected to increase with climate change. This is particularly evident in polar regions where reduced winter sea-ice has increased movement of icebergs, and thus seafloor scouring. […]
Sediment cores from two glacial lake basins in northeast Pennsylvania, USA, record the timing of Laurentide Ice Sheet (LIS) retreat along with post-glacial climate and environmental conditions. Basal radiocarbon ages […]
Global ocean warming is reshaping marine communities, with consequences for species- and community-level functioning. Serpulid polychaetes are a key component of benthic ecosystems that may be particularly vulnerable to rising […]
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, […]
