Primary production is the base of coastal food webs, yet it is difficult to measure this process, especially using automated procedures.
A classical method to measure primary production is based on the radioisotope 14C, but this is expensive and cumbersome.
Because of the challenges of working with radioisotopes, the department of Estuarine & Delta Systems (NIOZ, Yerseke) has developed novel methods for measuring primary production, one based on automated measurements of fluorescence of a water sample and another on continuous measurements of the oxygen concentration in surface water.
These novel methods are now in principle ready for more routine and continuous application in various marine ecosystems.
Therefore, we actively recruit a Technical Assistant for 2 years to apply these novel methodologies side-by-side in the Dutch Delta and North Sea.
You will apply the various methods to measure primary production in different ecosystems with a focus on the Dutch Delta, most notably the nearby Oosterschelde, and the North Sea.
You will prepare and pack equipment for regular day trips with a small vessel to the Delta or for longer trips (1-2 weeks) with a larger research vessel.
In addition, you will program the scientific instruments, perform measurements, take water samples and prepare samples for analysis in the laboratory.
Finally, you will help to develop a clear and concise data workup and archiving pipeline. The measurements will run in parallel with other projects that focus on the role and distribution of zooplankton in coastal waters and occasionally you are expected to be involved with these activities as well.
