鹿児島湾口山川港沖における噴気孔の確認 Confirmation of Submarine Fumarole off Yamagawa Port in Kagoshima Bay 内山, 正樹 101537 UCHIYAMA, Masaki 福田, 隆二 101538 FUKUDA, Ryuji 日高, 正康 12954 HIDAKA, Masayasu 1000020208771 452 Kagoshima Bay echo sounder ROV submarine fumaroles Submarine fumaroles was surveyed by using echo-sounder of training ship Nansei Maru, off Yamagawa Port located at a mouth of Kagoshima Bay in 2012 similar to a study by Fukuda et al. (2011)1). The submarine fumaroles were checked visually, when ROV was sunk in the point where the reflective image was obtained by echo-sounder, so this approach is effective to search the submarine fumaroles. It found by attached temperature gauge of ROV that water temperature in an upwelling of a submarine fumarole indicates 27ºC which is 9ºC higher than the surrounding area. Forty five points of submarine fumaroles were searched by echo-sounder. It is found that thirty nine points of them were concentrated in the narrow area within 500m radius around location at 31°-11′.7N, 130°- 40′.4E (WGS). departmental bulletin paper 鹿児島大学 Kagoshima University 2012-12-25 VoR application/pdf 鹿児島大学水産学部紀要 61 1 8 Memoirs of Faculty of Fisheries Kagoshima University 0453087X AN00040498 https://ir.kagoshima-u.ac.jp/record/2655/files/AN00040498_v61_p1-8.pdf http://hdl.handle.net/10232/17497 https://ir.kagoshima-u.ac.jp/records/2655 jpn open access
