Advisory boards  

NIOZ has a structure of formal advisory and network bodies that help to define and evaluate the strategy and to improve the positioning of the institute nationally and internationally.  

Institute Advisory Committee (IAR)  

The Institute Advisory Committee (IAR) functions as a societal network in the broadest sense. It contributes to maintaining and strengthening strategic relationships with science, corporate businesses, local, regional and national policies, and other relevant national parties within society. The IAR members all have an affinity with the research carried out at NIOZ and contribute expertise and advice from a wide range of perspectives. The IAR keeps the interests of NIOZ in mind and functions as a critical sparring partner for the institute director. The IAR meets once a year, while for specific issues the director consults with individual group members.

University Forum NIOZ (UF-NIOZ)  

Because of the institute’s national role in seagoing marine research and as national platform-provider (NMF), NIOZ installed a new networking body ‘University Forum NIOZ’ in 2022, to strengthen the links with the Dutch universities involved in marine research. The members of this Forum are at the level of dean, sometimes at the level of professor, at their universities. The aim of the Forum is to enhance collaboration and to strengthen marine scientific research in the broad sense in the Netherlands, with a view to developing joint research programmes and expeditions.
