Research Summary

Biogeochemistry of Aquatic Systems

In-situ Environmental Instrumentation

Research in the Hemond lab focuses on the geochemistry of aquatic ecosystems, with emphasis on the carbon and nitrogen cycles, and trace metal chemistry. Because spatial heterogeneity and transient processes often limit the ability to understand the functioning of such ecosystems, we are concurrently developing new means of measuring water chemistry by autonomous, mobile instrumentation.

As part of ESI we are studying the temporal and spatial chemical structure of aquatic ecosystems, and the extent to which structure informs us about underlying process. Novel instrumentation for observing chemical structure in freshwater and marine systems will be integrated with signal processing techniques in an effort to constrain underlying geochemical mechanisms.
