Ocean modeling of the Gulf of Mexico

François Counillon will defend his Doctoral thesis "Ensemble-based data assimilation and forecasting with an eddy-resolving model of the Gulf of Mexico" on Friday the 12th September at 13:15, at the Nansen Center/Geophysical Institute, University of Bergen.

The main objective of the thesis is to develop and validate a state of the art operational ocean forecasting system for the Gulf of Mexico region.

The thesis contains three referee publications on:

• Implementing a state of the art eddy resolving model for the Gulf of Mexico and analyzing the capability and limitations of the EnOI for assimilation of altimetry data. Revised and resubmitted for publication in Tellus.

• Using a small stochastic system for providing an additional predictability index to our forecast. Revised and resubmitted for publication in Ocean Dynamics.

• Combining the above stochastic system with the EnOI in a hybrid data assimilation system. Submitted for publication in Ocean Dynamics.

The Ph.D. works has been conducted at the Nansen Center under supervision by Dr. Laurent Bertino, Dr. Geir Evensen and Prof. Ola M. Johannessen.

The opponents are;
Dr. O.M. Smedstad, Stennis Space Center, USA, Prof. P.J van Leeuwen, Utrecht University, The Netherlands and Prof. Tore Furevik, University of Bergen

The public defense will take place at the Nansen Center in Thormøhlensgate 47 at Marineholmen.
