The video and data recorder consists of a low-light-sensitive video camera with near-infrared light-emitting diodes that is mounted on top of the seal's head to obtain close-up images of the seal's muzzle and the area in front of the animal. The main housing, which is mounted on the animal's back, contains an 8-mm video tape recorder that can record for 6 h, batteries, a microcomputer and transducers for pressure, water speed, compass bearing, and flipper stroke frequency. Sound is recorded on one audio channel of the tape recorder with a hydrophone. Using these instruments, we have recorded over 500 h of underwater video and over 1000 three-dimensional dive paths with corresponding swimming performance data from 31 adult Weddell seals. We have documented seals foraging in the water column, on the sea floor, and at the under-ice surface. Mid-water foraging included encounters with large Antarctic toothfish and smaller Antarctic silverfish. Multivariate statistical analysis of variables derived from the temporal and spatial characteristics of three-dimensional dive paths have enabled us to classify dive types and, in some cases, assign a function such as foraging.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733561","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Marine Biology, Texas A&M University at Galveston/Pisces Design/Department of Marine Biology, Texas A&M University at Galveston"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2004-03-01"}],"displaytype":"detail","filename":"KJ00000013102.pdf","filesize":[{"value":"257.6 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000013102","url":"https://nipr.repo.nii.ac.jp/record/2488/files/KJ00000013102.pdf"},"version_id":"840ca6d7-61c4-4484-8d5d-2e5820bf4878"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Monitoring the behavior and multi-dimensional movements of Weddell seals using an animal-borne video and data recorder","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Monitoring the behavior and multi-dimensional movements of Weddell seals using an animal-borne video and data recorder","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["412"],"pubdate":{"attribute_name":"公開日","attribute_value":"2004-03-01"},"publish_date":"2004-03-01","publish_status":"0","recid":"2488","relation_version_is_last":true,"title":["Monitoring the behavior and multi-dimensional movements of Weddell seals using an animal-borne video and data recorder"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T15:24:56.345729+00:00"}
