Abstract In Kongsfjorden (Spitsbergen), we quantified the zonation of visually dominant macroalgal taxa and detached macroalgae from underwater videos taken in summer 2009 at six transects between 2 138 m water depth. For first time, provide information on occurrence deep red algae below kelp forest depth > 30 m. The presence distribution were especially pronounced outer fjord, decreased with proximity to glacial front they absent innermost locations. Deepest crustose coralline foliose observed 72 68 m, respectively. Brown distributed along entire fjord axis 2–32 Green only present middle inner areas influenced by physical disturbance depths 2–26 With all became shallower extended 18 location. Major recipients sites photic zone They may either fuel secondary production, decompose or support carbon sequestration. Univariate community analyses classes including across over reveal a considerable difference structure outermost sites, central part areas, reflecting strong environmental gradients fjords.

Towards Incorporation of Blue Carbon in Falkland Islands Marine Spatial Planning: A Multi-Tiered Approach

Frontiers in Marine Science, Journal Year: 2022, Volume and Issue: 9

Ecosystem-based conservation that includes carbon sinks, alongside a linked credit system, as part of nature-based solution to combating climate change, could help reduce greenhouse gas levels and therefore the impact their emissions. Blue habitats pathways can also facilitate biodiversity retention, aiding sustainable fisheries island economies. However, robust blue research is often limited at scale regional governance management, lacking both incentives facilitation policy-integration. The remote highly biodiverse coastal ecosystems surrounding continental shelf be used better inform long-term ecosystem-based management in vast South Atlantic Ocean sub-Antarctic, synergistically protect unique on magnitude benefits they provide. Understanding key ecosystem information such location, extent, condition habitat types, will critical understanding sequestration, threats this, vulnerability. This paper considers current status data available, what still required before tool integrated national Marine Spatial Planning (MSP) initiatives. Our indicates gathered has enabled baselines for number different ecosystems, indicated potential vulnerability need managed. significant knowledge gaps remain across habitats, salt marsh, mudflats mesophotic zones, which hinders meaningful progress ground where it needed most.
