Abstract
This study aims at investigating structures of ocean current, salinity and water temperature in Miyako Bay, Iwate, Japan after the Great East Japan Earthquake. Field observation using CTD was performed at 0.1 m vertical intervals for 28 locations in the bay in September 6, 2013. Ocean current, salinity and water temperature in Miyako Bay were reproduced using a coastal ocean current model, CCM. The comparison between the numerical and observational results was conducted to verify the model results. As a result, it was demonstrated that the model can appropriately reproduce the salinity and water temperature in the bay. In addition, the characteristics of the ocean current, salinity and water temperature in the bay such as isolated water mass with low salinity in the east-central part of the bay were revealed by numerical analysis.
