- Relationships between the packaging of aquatic organic matter (in various size classes and particle morphologies), the molecular level characteristics of this organic matter, and the reactivity of this material in the water column. Various techniques employed include electrospray mass spectrometry, FTIR, chromatography, ultrafiltration, and analyses of radiocarbon and stable carbon isotopes.
- The Minor lab enjoyed having visiting professor Bruce Mattson (on sabbatical from Creighton University) join in lab and field work. His description of our May/June 2010 research cruise on Lake Superior can be found here.
