NIOZ Royal Netherlands Institute for Sea Research

NIOZ Royal Netherlands Institute for Sea Research is the national oceanographic institution for the Netherlands. Our mission is to conduct fundamental and frontier applied scientific research on important processes in delta areas, coastal seas and open oceans. The institute also acts as the national facility for academic marine research in the Netherlands. NIOZ facilitates and supports marine research and education in the marine sciences in the Netherlands and in Europe.


Dear visitor,

At this moment, our institute is in reorganisation and therefore we are developing an entirely new website. In the mean time, we will make provisional changes in the current website to allow our visitors to find the right information; e.g. our new (4) scientific departments and support departments and units. We apologize for the inconvenience. Should you be lost somewhere, please send an email with your question(s) to cpr@nioz.nl and we wil try to put you on the right track again.

Knots Must Scrape a Living in a Sea of Food

Press release 25 April 2016

Every year, knots migrate from their Arctic breeding grounds via our Wadden Sea to the south. There, they winter in Banc d’Arguin, an area full of contrasts, consisting of mudflats and bordering on the Sahara and the East Atlantic Ocean. The Sahara may be a sandy, dry place, but the mudflats are covered in seagrass and teem with life. Food galore for the knots, one might think. It so happens that knots have a unique sense in the tip of their bill that helps them find molluscs in dry mudflats superfast. However, on the rich Mauritanian mudflats, the seagrass hides the molluscs from the knots. This surprising mechanism as well as the fact that this game of hide-and-seek cannot be played in times of severe droughts were discovered by Jimmy de Fouw who conducted his PhD research at the NIOZ. His PhD defence ceremony will be held at the University of Groningen on 29 April.

App Measures Colour Palette of Lakes, Seas, and Oceans

Press release 14 April 2016

Marcel Wernand

Both fresh and salt water (natural water) can be many different colours, depending on other substances in the water. Moreover, the colour may vary with time, both seasonally and over longer periods of time. However, research cannot keep up with these changes, and that is why the general public is now asked to join the colour measurements using the Eye-on-Water App on their smartphones.

This app will be presented at the STOWA conference in Burgers Zoo on 20 and 21 April.

Symposium Cumulative Effects in Marine Ecosystems

Most coastal marine ecosystems, including the Wadden Sea, experience multiple environmental stressors simultaneously that can differ widely in their pathways and strengths of impact. An understanding of all relevant stressors is critical to prioritize conservation actions, including restoration, protection, and management. Yet, scientific concepts and empirical evidence on the separate and cumulative impacts of all relevant stressors is often insufficient to guide such decisions.

Surprising: food density is a bad predictor of bird numbers

Press release, 6 April 2016

It seems so logical: animals come together where food is abundant. Yet, it is not so simple, say scientists from the NIOZ Royal Netherlands Institute for Sea Research. Collaborating with engineers from the American Cornell University they developed transmitters to track bird movements, and discovered that Red Knots ignored places with the most abundant prey and preferred areas with high quality prey. Today, these findings are published in the leading scientific journal Proceedings of the Royal Society B.
