Stable and Radioisotopes of Carbon

Following carbon dioxide through terrestrial to freshwater ecosystems.

Following carbon dioxide through terrestrial to freshwater ecosystems.

We utilize the stable isotope carbon 13, and the radioisotope carbon 14 measured in aquatic carbon, we can begin to identify both its source to freshwater and marine systems, as well as the longevity of that carbon in the environment. 

Geospatial Analysis Along River Networks

We utilize large national and international databases on aquatic chemistry, in tandem with spatial data on stream, river, and lake locations to identify large scale fluxes across ecosystem boundaries. A strong emphasis is on GIS applications for carbon and nutrient flows from terrestrial to aquatic environments. 

Application of Remote Sensing Products to Identify Landscape Level Changes

Space based remote sensing technologies allow for near real time investigations into the impacts of changing seasons and land covers on aquatic ecosystems.

We apply creative and cutting edge field sampling technique to monitor aquatic carbon and nutrient biogeochemistry in remote environments.  New techniques are constantly being developed with an emphasis on greenhouse gas monitoring of aquatic environments.
