The bulk of our work is concerned with both basic and applied research. Among others, we develop new methods to use acoustical and optical properties (both from remote sensing and in-situ sensors) to quantify and characterize oceanic particulate materials.

Our research is most often done in collaboration with researchers from outside UMaine, both from other universities (e.g. OSU, WHOI, Dalhousie) as well as private companies (e.g. Sequoia Scientific and WETLabs).
