Where is the RV Pelagia?

The RV Pelagia is the NIOZ flag ship. With an overall length of 66 m, this versatile and stable vessel is suited for research on both coastal seas and open oceans (except for the polar regions).

2 weeks

Due to Arctic warming, spring starts 2 weeks early and hatching chicks miss the insect peak, ending up lighter, smaller and shorter-billed. Visit our Waddenflyways Blog >>>

Algal growth in Dutch coastal waters

Wadden Sytems Research Centre supplies easy access to expert teams, equipment, technology and protocols as developed for a variety of tidal environments

Building safe and productive deltas with nature

Climate change heats up water over 31 degrees Celsius bleaching coral reefs

Scientific Departments

Our science is conducted in four scientific departments;. Three of them are area oriented: estuaries and delta areas, coastal seas and open oceans. Marine Microbiology and Biogeochemistry conducts science in all three area types.

Key Areas

NIOZ performs maritime research in seas and oceans around the world. Our focus is on six key areas, including the home bases of our institute, the Wadden Sea and the Dutch Delta.

Wadden Sea

A unique coastal tidal environment and one of the main research areas

Dutch Delta

A protective boundary between land and sea, and a principal research area


Studying the rich biodiversity and functioning of the tropical region

North Sea

Balancing human use and healthy ecosystems in one of the busiest seas

North Atlantic Ocean

Crucial to our climate and harbouring unique ecosystems in its dark depths


Assessing the rapid change of the polar regions, which impacts our planet

Asian estuaries and coasts

The value and problems of Asian estuaries and coasts


An important part of the NIOZ mission is valorisation of our research efforts – what we like to call frontier-applied research. Successful examples include projects around ballast water, seaweed, tidal energy and deep-sea mining.
