Ocean Prediction Networking (OPNet)

Welcome to the Ocean Prediction Networking wiki.

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

The project is a collobarative project by and between the Norwegian Meteorological Institute met.no, Nansen Environmental and Remote Sensing Center NERSC, Institute of Marine Research IMR and Norwegian Institute for Water Research NIVA

Project leader is Lars Petter Røed, met.no/UiO

The project is funded by the Research Council of Norway RCN. Project started January 1, 2007 and estimated ending date is December 31, 2010. The project was officially ended by hosting a final seminar May 11 and 12, 2011, and is thus completed.

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 (models), 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

The approach is to arrange 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 seminar.

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.

We emphasize that no research per se is pursued. The underlying idea is that by organizing seminars at which views on how to improve ocean predictions are exchanged, the seminars should lead to an increased understanding of the weaknesses and strengths of the different forecast systems used by the various partners, and thereby lead to possibilities for efficient refinements and improvements. Another important outcome is that the seminars should lead to collaborative research proposals and research. One such example is the European project MyOcean funded by the EU Commission.

  • 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
