The most important and remarkable result is the very good oxygen situation in the 
North Sea in the summer of 2002 (Fig. 2c, near-bottom oxygen saturation). The 
DELPHIN measurements showed lower chlorophyll concentrations (Fig. 3); the 
Figure gives the DELPHIN data obtained on the east-west transects. Chlorophyll is a 
measure of phytoplankton production; here, the chlorophyll concentration is given in 
relative units. 
In the summer of 2002, less phytoplankton was generally observed in the North Sea 
than in the preceding three years. The observations made one year earlier have
