My main research interests are generally oriented towards the study of biogeochemical
cycles with a clear focus on the effects on, and effects of biota. Within this vast field
I focus on processes occurring at the interphase, whether it be sediment-water
interactions or air-water exchange. My earlier work investigated the beneficial effects
of iron on seagrass growth by titration of toxic sulphur species. Later on, I focused on
the air-sea boundary investigating the stocks of gaseous phase organic carbon both in air
and water and evaluating the exchange rates, especially as it relates to the DOC pool in
the water column and CO2 exchange. At SCU I will focus on carbonate biogeochemistry, both
organic and inorganic using a variety of approaches including, but not limited to,
spatial-temporal assessments, manipulative field experiments… and the suite of techniques
available at the CCB facilities.
