Project: The effects of changing Arctic sea ice cover on pelagic microbial organic matter utilisation: from composition to consumption
Supervisors: Dr Joanna Dixon (PML), Dr Fanny Monteiro (University of Bristol), Dr Sandra Arndt (Universite Libre de Bruxelles), Dr Karen Tait (PML), Dr Claire Widdicombe (PML)
The overarching aim of this PhD will be to understand how phyto- and bacterioplankton respond to changes in dissolved organic matter, from the perspective of functional composition and component dissolved organic carbon consumption in the water column (from surface to benthic-pelagic interface).
Patrick will participate in two Arctic research cruises sampling across spatial environmental gradients (drift ice to open-ocean, covering both Arctic waters and Atlantic inflow), and undertaking incubation addition experiments.
Arctic phytoplankton face competition in warming seas
As Arctic seas warm, important phytoplankton communities could find themselves competing for nutrients with encroaching Atlantic species, suggests new research from Plymouth Marine Laboratory. Read more23 September 2020
Arctic study to shed light on organisms key to the food chain
A research team – led by a University of Stirling expert – will set off on a scientific cruise to the Arctic Ocean this weekend in a bid to understand the behaviour of tiny organisms that are key to the food chain. Read more04 August 2019
