Around Antarctica, disturbance from iceberg scouring and natural macroalgal senescence result in the accumulation of macroalgal detrital material. This detritus in turn supports a significant abundance of detritivorous invertebrates and […]
Introduction: Migratory marine species face complex conservation challenges due to their dependence on habitats spanning vast scales. Humpback whales in the Western South Atlantic illustrate this complexity, undertaking long-distance migrations […]
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 […]
As extreme summer heat causes disruption across the UK and Europe this week, Midwinter at Antarctica’s Rothera Research Station is becoming increasingly unrecognisable.
This combined dataset presents major ion, macronutrient, and algal cell abundance data from supraglacial samples collected from three glaciers near Ny Alesund, Svalbard (Vestre Broggerbreen, Austre Broggerbreen, and Feiringbreen) during […]
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 […]
