Interests

• Biogeochemical processes in the Arctic including climate-related shifts in food webs and nutrient-trace element processes in the Chukchi and Beaufort Seas. Also, coastal erosion, sea ice melt and increased runoff from Arctic rivers.
• Biogeochemical processes in Florida waters (Indian River Lagoon and Florida Bay) that are influenced by shifting climate including potential for increased hypoxia and nutrient and trace element recycling.
