In United Nations Decade of Ocean Science, we hope to contribute to SDGs by the knowledge and technology of ocean science. One of the categories of ocean science defined in the UN Decade of Marine Science is "marine ecosystem functions and processes.” This category includes the marine ecosystem structure, diversity, chemical and physical process, nutrient cycling, energy flow, and others, because these support the richness of the ocean. To study t these, we need to examine the real ocean. On this page, you can learn about tools for quickly and safely collecting water near the shore. We would like to contribute to SDG 14 by spreading the fact that we can use such a tool to study the ocean environment.
