The United Nations has declared the Decade of Ocean Science, and while the prospects for the Blue Economy in Africa are promising, the development and use of the ocean and its resources remains unchanged from days past, and coordination and synergy on the regional and international levels are lacking. In order to facilitate early implementation of blue economy policies it is important to adopt systems incorporating new concepts, which I hope to promote through regional and international cooperation.

In this article, I will use historical documentation to introduce the work of Dr. Shizuo Ishiguro (1920–2007) during his time at Nagasaki Marine Observatory. Dr. Ishiguro was known for his pioneering work in using analog electronic circuits to identify complex oceanic phenomena and would eventually move from Nagasaki Prefecture to the U.K. I would also like to reflect on his research, which remains unfaded even now, on secondary undulations (abiki) in Nagasaki Bay, and discuss expectations for future research.

Change Our Next Decade is an organization of young people involved in a wide range of activities in the field of biodiversity conservation, aiming to "creating better society in living in harmony with nature.” Through trial and error, Change Our Next Decade continues to make policy proposals and conduct public awareness activities to resolve issues related to marine biodiversity. We will keep striving forward so that we can enjoy the bounty of the beautiful and productive ocean even throughout our future.
