Although large amplification of inertial oscillation was observed, the trajectories for 2 surface drifters clearly revealed the existence of clockwise circulation over the bay with typical speeds of 20~30 cm s-1. To confirm the formation of this circulation in summer, satellite Sea Surface Height Anomaly (SSHA) data were used to investigate the seasonal variability of flow pattern. We infer development of circulation in July and decline in October, i.e., the formation period during the latter half of sea-surface heating season.北海道大学大学院水産科学研究院Departmental Bulletin Paperapplication/pdfhttp://hdl.handle.net/2115/76380info:doi/10.14943/bull.fish.69.2.57https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/76380/1/bull.fish.69.2.57.pdf2435-3353北海道大学水産科学研究彙報69257692019-12-09jpnpublisher
