Time series


Total heat and mean temperature

The monthly mean value of heat content can be converted to the mean temperature of the total North Sea volume including the near-surface layers, and can thus be compared to the mean monthly surface temperature of the North Sea. Owing to the proximity of surface water to the energy source, i.e. the sun, the mean surface temperature is clearly higher than the mean value of the total water volume. The combined winter values show that vertical mixing takes place in the water column of the North Sea as soon as the surface water has cooled sufficiently in the course of the winter season. Vertical mixing transports oxygen to deeper water layers. As energy input increases in spring, a temperature stratification develops again, and mean temperatures rise in dependence on the strength and duration of energy input.
