    • Biogeochemical consequences of a changing Arctic shelf seafloor ecosystem 

      März, Christian; Freitas, Felipe; Faust, Johan Christoph; Godbold, Jasmin A.; Tessin, Alyson; Abbott, Geoffrey D.; Airs, Ruth; Arndt, Sandra; Barnes, David K.A.; Grange, Laura; Gray, Neil; Head, Ian M.; Hendry, Katharine R; Hilton, Robert; Reed, Adam J.; Ruhl, Saskia; Solan, Martin; Stevenson, Mark A; Tait, Karen; Ward, James M.; Widdicombe, Stephen; Souster, Terri A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-09)
      Unprecedented and dramatic transformations are occurring in the Arctic in response to climate change, but academic, public, and political discourse has disproportionately focussed on the most visible and direct aspects of change, including sea ice melt, permafrost thaw, the fate of charismatic megafauna, and the expansion of fisheries. Such narratives disregard the importance of less visible and ...

    • Climate Mitigation through Biological Conservation: Extensive and Valuable Blue Carbon Natural Capital in Tristan da Cunha’s Giant Marine Protected Zone 

      Barnes, David K.A.; Bell, James B.; Bridges, Amelia; Ireland, Louise; Howell, Kerry L.; Martin, Stephanie; Sands, Chester J.; Mora Soto, Alejandra; Flint, Gareth; Morley, Simon A.; Souster, Terri (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-16)
      Carbon-rich habitats can provide powerful climate mitigation if meaningful protection is put in place. We attempted to quantify this around the Tristan da Cunha archipelago Marine Protected Area. Its shallows (<1000 m depth) are varied and productive. The 5.4 km<sup>2 </sup>of kelp stores ~60 tonnes of carbon (tC) and may export ~240 tC into surrounding depths. In deep-waters we analysed seabed data ...
