Marine Biogeochemistry
• BIOPOLE (Biogeochemical processes and ecosystem function in a changing polar system) in collaboration with British Antarctic Survey & University of Exeter. Understanding of the lipid pump - a major conduit for carbon sequestration in the Arctic. Quantify pelagic-benthic coupling in food webs using calanoid biomarkers and show whether benthic animals increase the efficiency of the lipid pump by consuming overwintering animals at depth.
• SMARTEX (Seabed Mining and Resilience to Experimental Impact) and in collaboration with the University of Leeds BIOMEx (Biogeochemical Impact of Experimental Deep Sea Mining). Investigating the effects of deep-sea mining of polymetallic nodules from the abyssal seafloor in the Clarion Clipperton Zone on sediment organic matter and subsequent impacts on benthic ecology.
• EU's Horizon 2020 programme ATLAS working with international collaborators. Our work package focussed on understanding the food sources and food delivery pathways to sponge grounds, cold-water corals and coral gardens at our three case study sites in the Atlantic (Rockall Bank, The Azores and Davis Strait)
• iATLANTIC along with project partners DFO Canada deployed landers at Sambro Bank Sponge Conservation Area on the Scotian Shelf. I processed sediment trap material for lipid biomarkers to inform ecosystem management decision-making.
• NERC's COMICS (Controls over Ocean Mesopelagic Interior Carbon Storage) programme investigated organic matter in the mesopelagic zone and the role of the biological carbon pump, exporting carbon from the ocean surface to storage in the deep ocean. Investigating mesozooplankton physiological- and trophic ecology using lipid biomarker and stable isotope signatures
• NERC's CUSTARD (Carbon Uptake and Seasonal Traits in Antarctic Remineralisation Depth) programme examining the carbon remineralisation depth at a key junction of the global ocean circulation influences how long carbon is trapped in the ocean rather than escape to the atmosphere as carbon dioxide.
• NERC's SSB (Shelf Sea Biogeochemistry) programme investigating dissolved and particulate matter dynamics in the Celtic Sea
• Investigating planktonic foraminifera-bound organic carbon isotopes with Heriot-Watt University as a proxy to reconstruct environmental conditions in the upper ocean
• The effects of nanoplastics on krill development and seasonal trends in lipid profiles for copepods with BAS
Terrestrial Carbon Cycle
