Marine Biogeochemistry

Research Area: Marine biogeochemistry

Dr Schuster is a marine biogeochemist specialising in the study of the variability of the marine carbon cycle through observations and numerical techniques. She is a member of the observational group at Exeter that specialises in making and interpreting oceanic measurements of carbon cycle parameters at high accuracy. Her core research aims to understand the biogeochemical drivers of the changes observed in the marine carbon cycle, both the exchange of CO2 with the atmosphere at the sea surface and the transport of carbon in the ocean interior.

Dr Marie Jose Messias conducts research in the following areas:

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.
