About Us
Our group uses thermodynamic principles to assess the fate and transport of natural and anthropogenic compounds in the environment including:
- alkalinity and acidification in coastal systems
- air-sea gas transfer (bubbles & sea spray)
- carbon and nitrogen geochemistry
- emerging contaminants in coastal and far-shore environments
- Harmful Algal Blooms (HABs) and biogeochemical links
- chemical samplers and sensors (sulfate and contaminant samplers)
