Terrestrial Silica Cycling:
​What role does "terrestrial" biology play in regulating silica availability in downstream receiving waters? How do vegetated coastal systems impact the marine silica cycle?

---

Oysters as Biogeochemical Engineers:
How do oyster habitats (e.g., reefs, aquaculture) alter benthic metabolism? Do oysters increase nitrogen removal via denitrification? Can we use oysters to mitigate excess nitrogen?

---

Nitrogen Cycling in Coastal Ecosystems:
How does climate change alter benthic-pelagic coupling? What are the rates & controls of N fixation in estuaries? in aquatic systems? What's the role of hypoxia and pH in shifting benthic metabolism? What's the role of permeable sediments in removing nitrogen?

Watershed Nutrient Export:
​How does climate change alter nutrient export from forested watersheds? How do urban landscapes alter nutrient export and water quality? 

---

Coastal Greenhouse Gas Fluxes:
​What's the magnitude of nitrous oxide and methane fluxes in coastal systems? What environmental parameters control these fluxes? How do human activities change these fluxes across space and time?

---

New Lab Directions:
Can we develop low cost CO2 sensor packages? Can we develop a share model to improve access? Are macroalgae a host for pathogenic Vibrio? Changing primary production in Narragansett - exactly how much macroalgae is there?
