Research

Research interests

  • Transient tracers  such as Chlorofluorocarbons (CFCs), Sulfur Hexafluoride (SF6), Trifluoromethyl Sulfur Pentafloride (SF5CF3)
  • Tracer release experiments  (TRE)  in the ocean 
  • The use of transient tracers and TRE to study the rates and pathways of ocean circulation and ocean mixing rates
  • The use of transient tracers to improve the estimates of the oceanic uptake of anthropogenic carbon dioxide  (CO2)
  • The use of transient tracers  observations to evaluate numerical model simulations of  oceanic processes
  • Development for high precision analysis of trace gases in the atmosphere and ocean.
  • Climate change

Research projects

Diapycnal and Isopycnal Mixing Experiment in the Southern Ocean (DIMES,  July 2009 to August 2016). 
DIMES is a US/UK field program aimed at measuring diapycnal and isopycnal mixing in the Southern Ocean, along the tilting isopycnals of the Antarctic Circumpolar Current.

Radiocatively Active Gases from the North Atlantic Region and Climate Change  (RAGNAROCC, June 2013 to July 2017).
The overarching objectives of RAGNAROCC is to “Quantify and explain CO2 and other Green House  Gas fluxes in the North Atlantic and the processes giving rise to inter-annual and decadal variability”.
