NIOZ Open Days

In October 2026, NIOZ will host two Open Days to celebrate our 150th anniversary year! On 3 October our Open Day at Texel will take place, and one week later, on Saturday 10 October, we welcome you at NIOZ Yerseke.

Sea, Science, Society 

During these Open Days, you will get a look behind the scenes of our marine research. With activities, experiments and talks, NIOZ researchers will share their work, passion, and the wonders of our blue planet with visitors of all ages.
