Research Interests
  • High-resolution regional modeling of the coastal ocean for applications related to coupled physical/ecosystem/bio-optical processes, including analysis and evaluation using satellite and in situ observations
  • Real-time ocean forecast system development
  • Applications of satellite radar altimetry in coastal regions
  • Variational methods for assimilating coastal observing system data in models, and observing system design
  • High resolution nested modeling of interactions between estuary, shelf sea and deep ocean circulation
  • Estuary and coastal ocean carbon and nitrogen cycling
  • Coastal ocean air-sea interaction, waves, and sediment transport
Short History

John Wilkin has 25 years of international experience (U.S., Australia and New Zealand) developing and applying model-based analysis systems for interdisciplinary research (nutrient and carbon cycling; larval dispersal; ocean forecasting) in coastal and adjacent shelf and boundary current waters. Most recently, these projects emphasize using variational methods for assimilation of in situ and remotely sensed observations and the design of observing networks. He is a developer of the Regional Ocean Modeling System (ROMS) and co-convenes the annual ROMS User Workshops.

Wilkin is a member of NASA’s Ocean Surface Topography Science Team (OSTST) and is active in promoting uses of radar altimetry in the coastal ocean. He represents OSTST on the Global Ocean Data Assimilation Experiment (GODAE) Science Team (GOVST). Wilkin also co-chairs the User Working Group for NASA’s Physical Oceanography Distributed Active Archive Center (PO-DAAC), and is a member of the Ocean Observing panel for Physics and Climate (OOPC) of the Global Ocean Observing System (GOOS).

John Wilkin has lectured in international summer schools in France and Australia that train students and early career scientists on developments in modern coastal ocean observing systems and the interface between observing, modeling and ecosystems. He is a regular member of the Scientific Program Committee of the Coastal Altimetry Workshops that accompany meetings of NASA’s Ocean Surface Topography Science Team, and was chair of the 2015 Gordon Research Conference on Coastal Ocean Modeling. Wilkin has promoted international development and collaboration in applied coastal ocean modeling by co-convening more than 10 Regional Ocean Modeling System (ROMS) User Workshops in the US, Italy, Spain, Australia, France, Brazil and Croatia, and is a regular contributor to the online ROMS User Forum.
