Titel: 
On hunt for a wave climatology in the Atlantic Ocean - merging of data sources 

Abstract:
Knowledge of the variability of the wave climate at a given location of 
the world is important in ocean engineering e.g. for design purposes, 
planning of  marine operations, and ship routeing. In particular, the 
statistical distribution of significant wave height is of interest. By 
means of collected data, we are able to formulate a convenient model. 
These data may origin from different sources: measurements `in situ' 
(by buoy); satellite measurements; numerical wave models (hindcast). 
Each source has its advantages and drawbacks. 

I will present the on-going work at Ifremer of finding an operational 
methodology which will merge different data sources; one of the foremost 
keywords is interpolation. For a successful modelling, physical and
meteorological knowledge needs to be taken into account. The talk will 
commence with a broad introduction to data analysis within oceanography.
