Greetings to all,

The Global Ocean Data Assimilation Experiment (GODAE) final symposium will be held in Nice in November 12-15 2008. This
project has been a precursor to a world wide experiment to demonstrate the feasibility of global ocean observing systems using
state of the art assimilation techniques. Today, several teams are working on operational ocean systems to provide forecast and
description of the ocean, using increasingly complex assimilation schemes and high resolution models. As we saw in the last
newsletter, these systems have reached the coast and routinely provide real time ocean forecast. But they need input information
for their boundaries and initialisation fields, from regional, basin wide or global configurations.

This month, the Newsletter is dedicated to global ocean systems resulting from the GODAE project.

In the first news feature, a review of the GODAE achievements in ocean observing systems is made by Le Traon et al. In a
second introduction paper, Pierre Bahurel provides a “Global view on MyOcean” where he introduces the special ongoing efforts
to improve products and services to users.

Four systems from three countries (U.S., France and Japan) are then presented, showing a variety of developments, model
resolutions and assimilation schemes that are all facing the same challenges: to describe, understand and forecast the world
ocean. The first contribution is from Chassignet et Hurlburt and is dedicated to the U.S. HYCOM 1/12° global configuration.
Menemenlis et al. will then tell us how useful the ECCO2 system is in understanding and estimating ocean processes.
Legalloudec et al. follow with the 1/12° Mercator g lobal model and its ability to represent the mesoscale activity. Finally, Kamachi
et al. will present the MRI global systems, including two nesting configurations dedicated to several applications from climate
variability to boundary forcing or ocean weather.

The next newsletter will be published in January 2009 and dedicated to the Mediterranean Sea.

We wish you a pleasant reading.
