Welcome to the Ocean Prediction Networking wiki.

The objevtive of these pages is to inform about the project and to make the presentations delivered at the various OPNet seminars available.

The overall objective is to strengthen and formalize collaboration among Norwegian institutes actively involved in research and development related to marine forecasting. The collaboration is through organization of a series of formal seminars in which all partners are required to attend and to give contributions. The seminars involves discussion of methods, tools and systems whereby forecasts of physical and biogeochemical variables can be evaluated, forecast skills measured, and to recommend avenues whereby improvements can be made.

Specific objectives are:

• To monitor and discuss existing forecast products and their performance to help improving the tools and the methods used to produce the ocean forecasts
• To develop common validation tools that can be run to provide measures of the forecast skill
• To develop our understanding of the strength and weaknesses of the different model modules used by the partners
• To implement and operate a web-page for dissemination of forecasts, and forecast performance, e.g. skill measures

We emphasize that no research per se is pursued within OPNet. However, by organizing the proposed seminars, we believe weaknesses and problems in the predictions system will come to the forth, and methods and/or avenues that may be explored to solve them can be recommended. We envisage that one of the main outcome of OPNet is collaborative research and research proposals.

The approach is to arrange two two-day long seminars twice a year at Geilo, Norway. One to be held in spring and one in the fall. At least two scientists from each of the partners must attend each of them.

Also representatives from selected user group (e.g., offshore industry, yachtsmen, fishermen, governmental authorities, search and rescue organizations) and from foreign national groups dedicated to ocean prediction research are invited.

On the agenda is to discuss ocean prediction products, that is, tools and methods whereby they are produced, observational methods (in situ vs. satellite), data assimilation methods, numerical methods and numerical model implementations. Also results originating from other projects of relevance are discussed.

Focus initially is on methods whereby the skill of existing ocean prediction products is measured. This includes how the validation is performed, and how to develop, implement, monitor and disseminate the validation product. As the seminars proceed it is foreseen that also other products may be of interest to the partners.

The underlying idea is that the discussions at the seminars should lead to avenues and/or views on how to improve ocean predictions. Furthermore, that it should lead to an increased understanding of the weaknesses and strengths of the different forecast systems used by the various partners, and, finally, that is should lead to possibilities for efficient refinements and improvements.

It is foreseen that the discussions in the seminars lead to recommendations of other discussion products that needs to be developed. The development, implementation, monitoring and dissemination of such products are also part of the project.

• A strengthening of the national collaboration between Norwegian institutes actively involved in ocean forecasting
• A streamlining of techniques and tools whereby national Norwegian forecasts are made
• An increased exchange of information between the partners and the participants
• An improvement in the numerical models and techniques used for ocean prediction in Norway
• An increased awareness internationally of the status of Norwegian ocean prediction
• The Norwegian institutions become attractive partners in upcoming international collaborative projects funded under EU FP7

Project started January 1, 2007 and ended December 31, 2007. A total of eight seminars are arranged, the last and final on May 11 and 12, 2011.
