We work on the biogeochemistry of
metals (iron, cobalt, zinc, copper, chromium, and other), sulfide, and specific
organic compounds (folic acid, glutathione, and others), in the oceanic water
column, coastal waters, estuaries, and lakes. We study speciation of metals with
organic matter, their redox speciation, and the speciation of specific organic
compounds. We do get quite desperate sometimes. So, we decided to do some work
on microorganisms too: we are looking for feed-backs between speciation and
bio-availability. We are now growing Emiliania huxleyi and other algae and even
some bacteria in "realistic" cultures. This is of course different
from the unrealistic cultures which most other people may be growing. We mostly use cathodic stripping
voltammetry, usually with ligand competition to determine metal speciation.
