Using a grant from the National Science Foundation (EAR-0115900) we assembled a cost-effective and technically sophisticated instrument platform for coordinated biogeochemical investigations in lakes. The platform is based in a Godfrey Marine pontoon boat equipped with: four on-line FIA-based instruments (Fe, HOOH , and nutrient analysis), CTD (temperature, depth, conductivity, pH, eH, oxygen, fluorescence), GPS navigation, and a vibracoring system. This instrument provides the capability to measure multiple geochemical parameters in the water column and sediments over a range of scales - both temporal (seconds to centuries) and spatial (cm to km).
A diagram of the boat, the Colby Compass, is provided below. Please click on features of the boat for more information.
