First, a three-meter-long survey line was laid at Yayorigahama Beach in Okayama Prefecture. A steel can, a stainless steel knife, and a plug-in multi-tap were buried at 10 cm. Magnetic field intensity (MFI) and the magnetic susceptibility (MS) were measured on the beach surface. The MS values indicate a relatively higher value at the site where the steel can was buried 10 cm in burial depths, while such an increase was found at the depths of 20 cm, 30 cm, 40 cm and 50 cm. The peak of MFI could be recognized at the depths of 10 cm to 40 cm. This implies that the MFI test with an Overhauser magnetometer is more effective than the MS measurement. Magnetic anomalies of MFI were recognized on another survey line in Yayorigahama Beach where reinforcing iron bars were found at a depth of 90 cm. Our results indicate that the hidden iron items could be detected using an Overhauser magnetometer in the sand beach.</p>"}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410861936166330241","@type":"Researcher","foaf:name":[{"@language":"en","@value":"Hatakeyama Tadahiro"},{"@language":"ja","@value":"畠山 唯達"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"岡山理科大学 フロンティア理工学研究所"},{"@language":"en","@value":"Institute of Frontier Science and Technology, Okayama University of Science"}]},{"@id":"https://cir.nii.ac.jp/crid/1410861936166330240","@type":"Researcher","foaf:name":[{"@language":"en","@value":"Kawamura Noriko"},{"@language":"ja","@value":"川村 紀子"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"海上保安庁海上保安大学校　基礎教育講座"},{"@language":"en","@value":"Department of Liberal Arts, Japan Coast Guard Academy"}]},{"@id":"https://cir.nii.ac.jp/crid/1410861936166330242","@type":"Researcher","foaf:name":[{"@language":"en","@value":"Kitahara Yu"},{"@language":"ja","@value":"北原 優"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"高知大学 海洋コア国際研究所"},{"@language":"en","@value":"Marine Core Research Institute, Kochi University"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"18801323"},{"@type":"LISSN","@value":"18801323"},{"@type":"EISSN","@value":"18814689"}],"prism:publicationName":[{"@language":"en","@value":"Japanese Journal of Forensic Science and Technology"},{"@language":"ja","@value":"日本法科学技術学会誌"},{"@language":"en","@value":"Jpn.
