Upright and honest, she was very sensitive to the problems of the people who worked under her. For her many friends she was a kind and understanding confidante, who always found words of comfort and encouragement for those who needed them. A warm-hearted and just person – that is how we shall remember her. Requiescat in pace. Gdynia, 2 August 2011 “
“The North Sea region is the living domain of about 50 million people in nine highly developed

PF-562271 industrial countries. It is one of the best and most intensely investigated sea areas in the world. For accounts of the present state of knowledge, we refer the reader to Otto et al. (1990), Charnock et al. (eds.) (1994), Sündermann (ed.) (1994), Laane et al. (1996), Proctor (ed.) (1997), Ruddick K. (ed.) (1997), Prandle (ed.) (2000), Sündermann et al. (2001), Lozan et al. (eds.) (2003), Pohlmann (2003) and Pohlmann (2006). As far as the physical (oceanographic and meteorological), chemical and biological parameters of the North Sea are concerned, comprehensive data sets are available, providing three-dimensional distributions and time series from many decades. These data are constantly being supplemented by in situ observations and remote sensing information.

Major data centres for the North Sea are the BODC (British Oceanographic Data Centre), the DOD (German Oceanographic Data Centre) and PANGAEA (Data Tacrolimus Publisher

for Earth & Environmental Science). Furthermore, in the states surrounding the North Sea there exists a variety of complex computer models simulating the physical state of the water body for research purposes and for operational applications in hydrography, sociology http://www.selleck.co.jp/products/BAY-73-4506.html and economics (POLCOMS, NORWECOM, HAMSOM, BSH-mod). They are often coupled with models of the North Atlantic Ocean and the Baltic Sea (providing lateral boundary interactions) and with regional meteorological models of north-western Europe (providing atmospheric forcing). For estimating the quality of the currently available hydrographical and numerical data, see Delhez et al. (2004). It turns out, however, that remarkable data gaps still exist for spatial distributions of parameters (velocity, radiation, precipitation data) and with respect to long-term records (velocity, salinity data). New models for both research and routine purposes are still being developed. The trends are towards higher resolution, adaptive grids, coupling of physical, geochemical and biological sub-models and – more technically – towards data assimilation and the parallelizing of computer codes. Owing to the stochastic nature of the processes involved, ensemble runs are often carried out with subsequent model output statistics (MOS).
