Ms. Smyth began working with Drs. Liss and Yvon-Lewis in Spring 2012. Her project concerns whether ozone, deposited from the atmosphere, is able to affect the chemical speciation of metals in the ocean and their reactions with organic molecules in seawater. She is looking initially at its effect on manganese, which has several valence states that determine the metal’s bioavailability. The eventual aim of the project is to understand the effects of ozone on other metals as well. To date, she has constructed the necessary analytical apparatus for the measurement of manganese at ambient (nanomolar) levels in seawater, using chemoluminescence, and has combined and refined several published methods to determine the best analytical conditions and establish a reproducible calibration curve. The next step is to take natural water samples and expose them to ozone, with and without light, to see how (if) manganese concentrations change. She needs to include the effects of light as photochemistry is also thought to be involved with metal speciation changes in surface seawater.
