[7MgO-EqD-01] Second Cooperative Study of the Kuroshio and its Adjacent Region (CSK-2)

*Akira Nagano¹ (1. JAMSTEC (Japan))

Our knowledge of the Kuroshio is mostly based on data obtained in the international Kuroshio observation programme during 1965-1977, the Cooperative Study of the Kuroshio and Adjacent Regions (CSK). Most of ongoing long-term observations in the western North Pacific have been initiated since the CSK era. In addition, the activity of the CSK led to the establishment of WESTPAC as a branch of UNESCO/IOC. To take our current understanding of the Kuroshio to the next level such that it can benefit society, we have initiated the successor of the CSK, the CSK-2, since 2022 as a UN Decade Action project of UN Decade of Ocean Science for Sustainable Development (UNDOS). The CSK-2 contributes to UNDOS with two objectives: to elucidate the relationship between the Kuroshio Current and climate and weather, and its impact on marine ecosystems. As of now, 14 projects from 6 countries participate the CSK-2. To achieve the goals, we share information on progresses, discuss future cooperation and direction, and solicit new proposals. Stimulating research activities across the themes due to data sharing and gaining a deeper understanding of the Kuroshio and surrounding current systems due to data assimilation are future tasks and are working on them. In addition, we are eager to enhance collaborative research with numerical modeling and prediction communities. In this presentation, we introduce the present efforts of the CSK-2 for further collaboration with ocean modeling and prediction communities.
