From April 23-24 2018, deSter joined forces with By The Ocean We Unite and embarked on a 2-day expedition to discover the amount of plastic pollution currently present in the North Sea.

The aim of the expedition was to learn more on how plastic affects marine life, witness first hand scientific research conducted by The Ocean We Unite, and actively take part in a Beach Clean Up on the Dutch Island of Terschelling.

During the expedition, samples were collected using a “manta tray” which skimmed the sea looking for plastic. Afterwards the samples were analysed using a reduced sampling method. This was done under supervision of By The Ocean We Unite and according to set parameters in order to submit the research results to the 5 Gyres Institute’s database.

By the Ocean we Unite is a Dutch foundation with charitable status (ANBI) that contributes to preventing more plastics from ending up in our oceans. Through the organization of a variety of activities such as sailing expeditions, lectures and research, they aim to grow awareness, educate and activate people, organisations and governments to make much needed changes concerning marine pollution and sustainability.
