NIOZ Royal Netherlands Institute for Sea Research

The Royal Netherlands Institute for Sea Research (NIOZ) conducts marine research in Dutch and overseas waters from its Texel and Yerseke divisions. Its research areas, among others, include biology, physics, chemistry and geology.

Over 70 percent of the Earth’s surface is covered by seawater, and that water has a significant influence on the food cycle and the climate. Sea research contributes to knowledge that enables the sustainable exploitation of the planet. For example, NIOZ conducts experiments on the cultivation of seaweed and salt-water algae for food, medicines and biofuels. Its deep ocean work yields a wealth of practical information for the offshore industry. In addition, NIOZ tests systems for the treatment of ballast water in shipping.

NIOZ has its own ships, specialised laboratories and technical workshops where innovative equipment is developed and built. NIOZ is always on the look-out for new partnerships with research institutes, universities and companies.


NIOZ was founded in 1876 as the Zoological Station in Den Helder. It is one of the oldest oceanographic research institutes in Europe. In 1970, the institute moved to the island of Texel, giving it access to flowing seawater in the laboratories and a dedicated harbour. At its 125th jubilee year, NIOZ was granted permission to use the designation ‘Royal’.

In 2012, the Centre for Estuarine and Marine Ecology in Yerseke became a division of NIOZ.
