The 3D structures and temporal variations of typhoon-driven coastal upwelling are mapped by data assimilation of travel-time data into Princeton Ocean Model (POM)
Coastal acoustic tomography
Data are grouped into three:
First group: coastal acoustic tomography data obtained at acoustic stations H1, H2, H3 and H5, located at the periphery of the bay.
(1) travel time difference data proportional to path-average current velocity
(2) travel time summation data proportional to path-average sound speed (temperature)
Second group: temperature array data obtained at the raft station near Nino-shima Island.
The 5-min interval temperature are obtained at depths 0, 2, 4, 7, 10 and 15 m.
Third group: CTD (conductivity-temperature-depth) data obtained at 10 stations (C1-C10) distributed over the bay. One-time CTD casts were done during 11:00-13:00 of September 18, 2013. Data were sampled at a 0.1-m interval at each station.
Data Time Period: From September 11 to 23
GeoLocation: Hiroshima, JAPAN
Dataset Progress Status: complete
Use Limitations: No limitation
Funding Reference: JST A-STEP program (AS242Z01178H)
