Research Interests

I am interested in the determination of dissolved trace metal concentrations in seawater and what the resulting concentration data tells us about physical, chemical, and biological processes. The area of study is the mesoscale anti-cyclonic eddies that form off the coast of the Queen Charlotte Islands in the winter months (Haida eddies).   These eddies transport coastal water, which contain high metal and nutrient concentrations, westward into the Alaskan gyre. The Alaskan gyre is considered a high nutrient, low chlorophyll region where primary production is limited by iron. The Haida eddies may be a form of iron introduction to the gyre. By using other trace metals as tracers of iron inputs and removals (since the iron system is complex) we hope to get a better idea of the importance of iron removal mechanisms. The study of these eddies also gives us a chance to study coastal water as it ages, since there is limited interaction with surrounding waters. This allows for calculation of removal rates of trace metals.

This research is done in collaboration with the Institute of Ocean Sciences, DFO in Sidney, British Columbia.
