Research Interests

  • Trace metal geochemistry
  • GEOTRACES
  • Analytical chemistry
  • Stable metal isotopes
  • ICP-MS methodology

My work focuses on trace metal cycling and dynamics in the Arctic Ocean. Specifically, I employ trace metal geochemistry as a tool to quantify and examine physical, biological, and chemical processes related to sea ice melt, riverine input, and water mass influence, among others. Within the diverse category of trace metals I focus on dissolved, colloidal and soluble fraction analyses. My goal is to see how trace metals in the ocean respond to the rapidly changing polar environment of the Arctic Ocean and what we can learn from that relationship. Currently, my method uses ICP-MS to analyze for Fe, Mn, Ni, Cu, Zn, Co, Cd and Pb. This work is part of a collaboration with the NSF-supported, international GEOTRACES study.
