Abstract

This study is aimed at numerically discussing the formation mechanism of intermittent subsurface-layer hypoxia in summer season in Ise bay. The long-term variation of hypoxia was examined by using a quasi three-dimensional numerical ocean model with MOVE-WNP data, which are dataset of an ocean variational estimation system in Western North Pacific. The numerical result revealed that hypoxia in the subsurface-layer was formed by the intermittent intrusion of oceanic water into the bottom layer of the bay. The MOVE-WNP data were also confirmed to be useful in comprehending the influence of ocean on internal structure in a bay through the numerical experiments.
