| Zusammenfassung |
| SeaDataNet(1) is a pan–European network connecting the existing professional
marine data centres of 35 countries. It is currently setting up a data management
infrastructure consisting of a standardized distributed system. Development and adoption of
standards for communication and Quality Assurance issues, will offer the users
access to consistent datasets and products through the unique portal of a virtual data
centre.
In order to demonstrate the proof of concept the consortium has started to elaborate
integrated products, using common procedures and methods, as if data were already available
through that unique portal. Among these, the computation of climatologies for the various
European regional seas, the Atlantic and the global ocean.
The poster shows the progresses made so far in establishing salinity and temperature
climatologies for the North Sea. Therefore, CTD data from various sources are
analyzed using the Variational Inverse Method (Brasseur et al., Deep-Sea Research
I,
textbf43:159-192, 1996) over the period 1975-2005.
The analysis provide better resolution of basin-scale processes absent in global
climatologies. Moreover, physical constraints such as advection and boundaries are
directly considered during the interpolation process, making the resulting fields more
relevant.
This standardization effort will greatly improve the overall quality of the final product
and, hence, its usefulness for the users (like modellers). The methodology will be later
applied to parameters like nutrients concentration.
