Abstract: | The dynamics of dissolved oxygen (DO) were studied during a typical wind condition for each season in Lake Kasumigaura, a hypereutrophic lake. Vertical and diel fluctuation of DO was extremely dynamic during the summer algal bloom in August. As the vertical transport of DO for the typical local-wind (1 to 2 m s?1) was only one order of magnitude greater than for at the windless condition, the stability of oxygen conditions in the dysphotic zone could not be disturbed greatly by the wind stress. |
