Climate Science
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. […] The post Shallow benthic Antarctic food webs recover complexity after disturbance appeared first on British Antarctic Survey.
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 […] The post Ikaite precipitation indicates near surface occurrence of methane in an Icelandic fjord appeared first on British Antarctic Survey.
Antarctic, Southern Ocean, and Global Ocean Temperatures during Dansgaard–Oeschger Events [preprint]
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 […] The post Antarctic, Southern Ocean, and Global Ocean Temperatures during Dansgaard–Oeschger Events [preprint] appeared first on British Antarctic Survey.
Extreme environmental events (EEEs) in Antarctica and the Southern Ocean are occurring with growing frequency and severity, and will become more pronounced under continued global warming. Antarctic research relies on […] The post Antarctic science operations must account for climate change and extreme environmental events appeared first on British Antarctic Survey.
Climate change is reshaping contaminant pathways in Antarctica by mobilizing rare earth elements (REEs) and heavy metals from the cryosphere into marine ecosystems. Thaw-driven changes in salinity, pH, stratification, and […] The post Climate-Driven Mobilization of Rare Earth Elements and Metals in Antarctica: Pathways, Ecological Exposure, and Implications for Trophic Transfer appeared first on British…
Ecological roles, climate-driven responses, and critical knowledge gaps of krill in the global ocean
Human-induced global climate change and other anthropogenic stressors are fundamentally altering our oceans. Understanding the ecological and societal implications of these changes is critical for developing mitigation strategies and conservation […] The post Ecological roles, climate-driven responses, and critical knowledge gaps of krill in the global ocean appeared first on British Antarctic Survey.
Increasing human activity and climate change in Antarctica may increase the rates of non-native species introduction and establishment, resulting in potentially irreversible changes in marine and terrestrial ecological communities. The […] The post Grass is not always greener: enablers and barriers of non-native species governance and management in Antarctica appeared first on British Antarctic Survey.
Background Antarctic marine food webs are expected to be significantly impacted by future climate change. In particular, the recent rapid regional warming in the West Antarctic Peninsula has, and will […] The post The effects of feeding guild, seasonality, and warming on the gut microbiomes of Antarctic echinoderms appeared first on British Antarctic Survey.
How climate change impacts pathogens in the natural environment is a critical ecological question. Yet, little is known of how rapid ongoing climate change in Antarctica and Patagonia will influence […] The post Climate Change Projected to Double the Richness and Abundance of Soilborne Phytopathogenic Fungi in Southern Maritime Antarctica appeared first on British Antarctic…
