Marine Conservation Day at “Sharky am Schloss” - the sharks were loose in Bensberg. 50 children participated and went swimming with "Haidemarie". As always, there was much information worth knowing about the ocean to explore: The focus was on the ecosystem and its inhabitants, but also on the correct handling of plastic and the associated avoidance of single-use plastic.

At the end of the day, we looked into the happy eyes of our junior marine conservationists.
As demand was enormous, we will attempt to offer several dates in Bensberg in 2026. We will presumably announce them on our homepage from February onwards.

We thank the Sharky Schwimmschulen, Martin Becker and his team, for the repeated opportunity to host our marine days at your locations and the magnificent support from your professional swimming instructors.

Quieter thanks to bubble curtains: noise mitigation (not only) for marine mammals

Fundamentally, a high background noise level already exists in the ocean due to wind, waves, and precipitation: depending on the frequency, this is around 80–90 dB, which is comparable to a passing lorry.
