NIOZ Open Day Yerseke
On Saturday 10 October, NIOZ Yerseke will open its doors to the public for an Open Day. With activities, experiments and talks, our staff will give you a look behind the scenes of marine research.
Sea, Science, Society
Are you curious to the very bottom? Dive into the depths at our Open Day! Observe marine life through a microscope or in the aquariums, and get hands-on with plankton, seaweed and oysters. Look through VR goggles, build a sea wall out of Lego and learn more about coastal protection and rising sea levels. There’ll also be talks, an exhibition marking 150 years of NIOZ, and demonstrations of our research equipment. This is how we’ll show you how water, science and our world are all connected.
Below are a few examples of the many things on offer that day. We’ll be updating the programme over the coming weeks, so keep an eye on this webpage.

The puzzle of the food web
An alga is eaten by a fish, which in turn is eaten by a bird. That seems like a simple chain of predation. But in reality, the food web is much more complex. Can you piece together the puzzle of the food web in the Wadden Sea?

Dike breaches
To protect ourselves from rising water levels, we have to keep building our dykes higher and higher. Or is there another way? Build a dyke out of Lego and discover how plants can help make our dykes stronger and better protect us against rising sea levels.

Invisible life in the water
A drop of seawater may look clear, but it’s actually teeming with life! Discover this in our plankton lab, where you can use a microscope to examine various ‘water droplets’ and learn all about these tiny plants and animals.
A bit more about seaweed
Is seaweed the food of the future? Come and see what different types of seaweed live in the local area. You can make your own seaweed art, learn more about what you can use seaweed for (not just for eating!) and why it’s a good idea to do so.
