The One Ocean Expedition can give us better understanding of levels and transport routes of microplastics in the ocean
Under the framework of the UN Decade of Ocean Science for Sustainable Development, the tall ship Statsraad Lehmkuhl has started a 20-month circumnavigation, the "One Ocean Expedition" in August 2021 with the ambition to "create attention and share knowledge about the crucial role of t...

Under the framework of the UN Decade of Ocean Science for Sustainable Development, the tall ship Statsraad Lehmkuhl has started a 20-month circumnavigation, the "One Ocean Expedition" in August 2021 with the ambition to "create attention and share knowledge about the crucial role of the ocean for a sustainable development in a global perspective" (https://oneoceanexpedition.com).
