Sea water systems Kristineberg

For both deep and surface water entering the Kristineberg Main Building, salinity and temperature are continuously measured. It can be seen on the Weather data web page. Compiled measurement results from 2007-2013 and 2016-2018 are shown in diagrams below.

Deep water
The deep water intake is at 32 metre depth. It is pumped up through the Main Building to a water reservoir on the third floor. The water is flowing through four serie-connected tanks, where sediment and large particles sinks. From the last tank, the water flows down through the building to the laboratories. In the thermoregulated rooms there are screen filters in the taps. In other labs, water is unfiltered.


Salinity of deep water in the laboratories, mean (bold line) with 95% confidence interval (blue). Highest and lowest measured values are 35.2 PSU and 26.5 PSU, respectively.


Temperature of deep water in the laboratories, mean (bold line) with 95% confidence interval (blue). Highest and lowest measured values are 21.0 °C and 1.4 °C, respectively.

Surface water
The surface water intake is at 5 metre depth. This water is usually available in the laboratory from April to November. The water is pumped to the water reservoir on third floor of the Main Building. From here it flows through tanks and down into the laboratories.


Salinity of surface water in the laboratories, mean (bold line) with 95% confidence interval (blue). Highest and lowest measured values are 33.5 PSU and 15.6 PSU, respectively.


Temperature of surface water in the laboratories, mean (bold line) with 95% confidence interval (blue). Highest and lowest measured values are 22.1 °C and 4.7 °C, respectively.
