DIDSON is an acoustic lens-based sonar. Institute of Industrial Science, University of Tokyo (IIS) has understood DIDSON\u0027s superior performance and tried to find new method for utilization of it. A next challenge is to develop an observation method based on DIDSON for hydrothermal discharging from seafloor vent. In October 2009, we conducted seafloor reconnaissance using a manned deep-sea submersible (DSV) Shinkai 6500 in Central Indian Ridge 1820deg. S, where hydrothermal plume signatures were previously perceived. DIDSON was equipped on the top of Shinkai 6500 in this cruise. DIDSON could obtain acoustic images of seafloor hydrothermal flows, even though we could not fully utilize the performance of DIDSON due to low-quality wire connection between DIDSON and Shinkai6500. Contrasting density inside the acoustic image of the hydrothermal flow could be distinguished. DIDSON showed its possibility of observation tool that can delineate spatial and temporal change of internal structure of the hydrothermal flows. © 2011 IEEE.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1109/UT.2011.5774118"}}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Masashi Mochizuki", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Akira Asada", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Kensaku Tamaki", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Jun Han", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Zengo Yoshida", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "Utilization of acoustic video camera for investigating mid oceanic ridge", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Utilization of acoustic video camera for investigating mid oceanic ridge", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "10", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/6780", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2024-09-23"}, "publish_date": "2024-09-23", "publish_status": "0", "recid": "6780", "relation": {}, "relation_version_is_last": true, "title": ["Utilization of acoustic video camera for investigating mid oceanic ridge"], "weko_shared_id": -1}
