Abstract:

My long term goal is to contribute to our understanding of coastal ocean circulation through the application of tracer signals for water mass identification. Of particular interest to me is the distinction of freshwater sources, be they riverine, local precipitation or ice melt and the effects of their transport pathways and chemical contents on the health of coastal ecosystems. My laboratory group has shown that its biogeochemical characteristics render barium a useful tracer of riverine inputs on the 10s to 100s of km spatial scales. The ultimate objective of this project is to establish a technique for the in-situ determination of barium in seawaters. An intermediate step toward achieving that goal is the development of a ship-board technique so as to be able to use barium distributions to make near real time sampling decisions in the field.
