The purpose of this study is to analyze the relationship between high turbidity and sulfur, and transfer of a blue tide after upwelling. We achieved ship observations of a blue tide at 24th August 2015 on the inner part of Tokyo Bay. There was a definite positive correlation between turbidity and sulfur from analysis of water samples. Therefore, high turbidity indicates the particulate sulfur element in a blue tide. Upwelling water of the blue tide outflowed to the middle layer for analyzing a composition of the blue tide water. It was considered that a density of upwelling water decreased slightly due to mix with around surface water. The blue tide water drifted on a pycnocline for wind driven current and density current.
