Research Interests

  • The role of the coastal ocean in global biogeochemical cycles.
  • Mechanisms for transport of dissolved and particulate nutrients on and off the shelf.
  • The role of the winds, stratification, shelf size, freshwater forcing, and sea level changes on exchange between the coastal and open ocean.
  • Controls over source water depth for upwelled water and how that might change in a global warming world.
  • Ocean acidification in the coastal ocean.
  • Numerical Models of the coastal ocean.
  • Tracer design and implementation in models
