NWO Institute NIOZ: Royal Netherlands Institute for Sea Research

NIOZ, the Royal Netherlands Institute for Sea research, is an institute that is part of NWO-I and it closely collaborates with Utrecht University.

What does NIOZ do?

As the national oceanographic research Institute, the Royal Netherlands Institute for Sea research has carried out multidisciplinary fundamental seagoing research into important scientific and societal issues concerning the functioning of delta and coastal areas, seas and oceans for almost 145 years. NIOZ also manages the national research vessels and the equipment for the Dutch research community. Furthermore, NIOZ encourages and supports marine research, education and policy development at the national and international levels. In 2018, NIOZ was assessed by an international evaluation committee as excellent and world leading.

Why sea research?

We inhabit the blue planet: more than 70% is covered by sea, and oceans produce more than 50 percent of the oxygen on earth. Oceans are the most important buffer for CO2 and global warming. Many answers to the major, societal issues that are high on the Dutch, European and global agendas can be found along the coasts and in the seas and oceans. Whether this concerns the opportunities these provide (as a source of energy, food, raw materials, transport, tourism, nature), or solutions for the problems (pollution, overfishing, the consequence of climate change). Healthy, productive deltas, seas and oceans are of considerable ecological, economic and geopolitical importance for the Netherlands and the Caribbean parts of the Kingdom of the Netherlands. Sea research is desperately needed because utilisation and protection both start with understanding.

The course of NIOZ

We live in the Anthropocene epoch in which human impact is increasing and natural circumstances and the environment are changing considerably. NIOZ researchers want to understand how the important marine systems, and the processes within these, play a role in this with a clear emphasis on biodiversity, ecosystem architecture and the CO2 cycle. A better understanding of this provides the basis for society to tackle the major challenges and to set a sustainable course.

The people of NIOZ

At NIOZ, there are 325 dedicated employees who come from more than 25 different countries. About half of these employees do research ranging from the delta to the deep sea and the other half is vital for the support of the researchers. With each other, and together with colleagues in the Netherlands and abroad, they work hard on safeguarding our oceans, coasts and future.

NIOZ as nexus

NIOZ works nationally and worldwide together with universities, research institutes, universities of applied sciences, NGOs, companies and government bodies. As the national oceanographic Institute, NIOZ represents the Netherlands in many partnerships, such as the think tank for European Marine science policy, the European Marine Board (EMB), and the Partnership for the Observation of the Global Oceans (POGO).
