• Benthic Biodiversity, Carbon Storage and the Potential for Increasing Negative Feedbacks on Climate Change in Shallow Waters of the Antarctic Peninsula 

      Morley, Simon A.; SOUSTER, TERRI; Vause, Belinda J.; Gerrish, Laura; Peck, Lloyd S.; Barnes, David K. A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-17)
      The importance of cold-water blue carbon as biological carbon pumps that sequester carbon into ocean sediments is now being realised. Most polar blue carbon research to date has focussed on deep water, yet the highest productivity is in the shallows. This study measured the functional biodiversity and carbon standing stock accumulated by shallow-water (<25 m) benthic assemblages on both hard 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 ...
