抄録: Nutrient distributions (NO^-_3,NO^-_2,PO^<3->_4,SiO_2) were measured in Kuroshio Warm-Core Ring (WCR) during the Hakuho-maru cruise KH-97-3. WCR is occurring as a transit zone between the Kuroshio and Oyashio. In generally, it is thought that organic production is much greater at the edge of WCR than at the center of that. Concentration of chlorophyll-a is also higher at the edge of WCR than center of that. But, We have no clear interpretation about the mechanism of nutrient supply, especially to the edge of WCR. We had studied hydrographic of WCR structure using potential T, S, σ_θ and nutrient. Consequently, I had gotten new hypothesis on WCR structure : The edge of WCR has lower than sea surface and mulchlayered structure from surface to bottom of WCR. This WCR structure will bring to the small scales upwelling around top of edge, which supplies nutrient to the edge of WCR, and maintains the higher organic production at the edge.
