Research interest and drive

I am a scientist performing fundamental research, interest driven. However, I need to see a cause for my research. This cause is most often to understand part of the ocean ecosystem. As an illustration: Iron is an interesting element since it has a complex chemistry in seawater, depending on pH, oxygen and organic content of seawater. However, for me inspiring is that this element is essential for growth of phytoplankton and limits this growth in large parts of the oceans near the surface.
I study metals in seawater, with the main focus on iron and specifically the chemical forms of iron in seawater. These chemical forms define the residence time of iron in seawater and its bio-availability.

Ultraclean water sampler

View the underwater operation of the NIOZ PRISTINE Ultra-clean water sampler for the determination of low concentrations of trace metals in the open ocean waters.

To prevent contamination during sampling, 24 “PRISTINE” bottles each with a volume of 24.4 L, made of a high-purity polymer Polyvinylidene  Fluoride (PVDF) are mounted on an all-titanium frame. To open and close the bottles use a butterfly valve system allowing a large opening at the top and bottom. Before deployment bottles remain always closed when onboard and only open after deployment at 25 m depth, preventing contamination from the ship. This sampler is an example of the co-operation at NIOZ between scientists and technicians as illustrated in the author list of the paper describing the functioning of the ultra-clean sampler:
