CLEAN : Swiss boat maps ocean

The video discusses the presence of microplastics in global samples, even in remote areas like the Pacific and Patagonia. It highlights challenges in data collection and the impact of sonar and oil exploration on the ocean. Inspired by Magellan's journey, the project aims to share data with the scientific community and raise awareness about noise, greenhouse gases, and microplastic pollution.
