Job at the Royal Netherlands Institute for Sea Research (NIOZ) – PhD student “Dynamics of acidification in the North Sea”

PhD student “Dynamics of acidification in the North Sea” wanted by The Department of Biological Oceanography from The Royal Netherlands Institute for Sea Research (NIOZ)

Job description

Burning of fossil fuels has led to accumulation of carbon dioxide in the atmosphere. This has two major consequences, namely global warming and ocean acidification (“the other CO2 problem”). Sea surface water pH has decreased already by 0.1 unit, and based on atmospheric CO2 scenarios, it is projected to further decline by 0.0015-0.002 unit per year over the coming century. However, observations in the North Sea show stronger decreases of 0.02 unit per year. The North Sea is apparently acidifying 10 times faster than global ocean model predictions.

This may have effects on photosynthesis by algae and bio-calcification by shellfish. It is essential to verify if indeed acidification of the North Sea is going very fast. This will be assessed by very accurate measurements onboard research vessel Pelagia, interpretations also by computer simulation of biology-chemistry-physics interactions of the entire North Sea, and publication of articles in international journals. Implementation of the research will be developed by the team with significant freedom of choices.


The successful applicant holds a BSc&MSc university diploma in natural science (chemistry, pharmacy, physics, biology) or engineering. Skills in modern computer-driven analytical chemistry, mathematics, simulation modeling, English writing, or sea-going experience would be an advantage but are not required. We expect that the candidates will successfully complete a PhD thesis.

Conditions of employment

We offer a full-time PhD position for 4 years, a pension scheme, a yearly 8% vacation allowance, year-end bonus and flexible employment conditions. Conditions are based on the Collective Employment Agreement for Research Institutes. Cost of relocation and help with housing is provided by NIOZ.


The Royal Netherlands Institute for Sea Research (NIOZ)

The Royal Netherlands Institute for Sea Research (NIOZ) is the leading research institute in the Netherlands for the basic marine sciences. Five departments (Physical Oceanography, Marine Geology, Marine Organic Biogeochemistry, Biological Oceanography and Marine Ecology) carry out the multidisciplinary research of the institute. Approximately 250 persons are currently appointed at the NIOZ. NIOZ has a large variety of instrumentation and is operating modernly equipped research vessels for coastal and ocean studies. The institute is located on the Wadden Island of Texel, close to the mainland.
