| Research Abstract |
This study was first planned based on the paper "Dynamical study on the bay-typed shelf circulation and heat and water mass transport across the shelf break" by T.Sugimoto and J.A.Whitehead (1983). This theoretical and experimental study was extended to the infinite long shelf without side wall boundary (Whitehead, 1993) and its nonlinear theory (Whitehead and Kimura, to be published). Kimura also investigated generation and evolution of the frontal eddies in the rotating hydraulic model (Kimura et al., 1993).
Comparative study on the shelf break circulations and coastal boundary circulations of the western boundary currents between the Kuroshio and the Gulf Stream was also conducted, mainly by T.Sugimoto and H.Nakata. In this study fluctuation of the Kuroshio front and the accompanying frontal eddies and streamers are precisely investigated through intensive field observations (Kasai et al., 1993).
In relation to material exchange in and around the shelf break, Y.Hozaki in ORI and S.Honjo in WHOI worked to make clear the dispersion of the dissolved and suspended matters, respectively, from the Yangtze River on and across the East China Sea shelf (Nozaki, 1991).
