We found 2 to 4 microgal diurnal/semidiurnal signals in the time series of absolute gravity measurements. These signals agreed well with theoretical ocean tide both in amplitude and in phase, demonstrating that the FG5's precision is better than 2 microgal. Furthermore, we found that the discrepancy between the FG5 measurements and the SG measurements is 1.3 to 1.5 microgal. These results verify that the FG5 is precise to 1 to 2 microgal.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381699994745309440","@type":"Researcher","foaf:name":[{"@value":"Shuhei Okubo"}]},{"@id":"https://cir.nii.ac.jp/crid/1381699994745309443","@type":"Researcher","foaf:name":[{"@value":"Shigeo Yoshida"}]},{"@id":"https://cir.nii.ac.jp/crid/1381699994745309442","@type":"Researcher","foaf:name":[{"@value":"Tadahiro Sato"}]},{"@id":"https://cir.nii.ac.jp/crid/1381699994745309444","@type":"Researcher","foaf:name":[{"@value":"Yoshiaki Tamura"}]},{"@id":"https://cir.nii.ac.jp/crid/1381699994745309441","@type":"Researcher","foaf:name":[{"@value":"Yuichi Imanishi"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00948276"},{"@type":"EISSN","@value":"19448007"}],"prism:publicationName":[{"@value":"Geophysical Research Letters"}],"dc:publisher":[{"@value":"American Geophysical Union (AGU)"}],"prism:publicationDate":"1997-02-15","prism:volume":"24","prism:number":"4","prism:startingPage":"489","prism:endingPage":"492"},"reviewed":"false","dcterms:accessRights":"http://purl.org/coar/access_right/c_abf2","dc:rights":["http://onlinelibrary.wiley.com/termsAndConditions#vor"],"url":[{"@id":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1029%2F97GL00217"},{"@id":"https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/97GL00217"}],"createdAt":"2004-02-04","modifiedAt":"2023-11-22","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050303932801089280","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"A possibility of fluid migration due to the 2023 M6.5 Noto Peninsula earthquake suggested from precise gravity measurements"}]},{"@id":"https://cir.nii.ac.jp/crid/1360285709394409216","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Imaging the density profile of a volcano interior with cosmic-ray muon radiography combined with classical gravimetry"}]},{"@id":"https://cir.nii.ac.jp/crid/1360302865736607616","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Postseismic gravity changes after the 2011 Tohoku earthquake observed by superconducting gravimeters at Mizusawa, Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1390001206510988800","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Absolute gravity change associated with the March 1997 earthquake swarm in the Izu Peninsula, Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1390565134827096576","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Advances in gravity analyses for studying volcanoes and earthquakes"}]},{"@id":"https://cir.nii.ac.jp/crid/2051433317008464896","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Temporal gravity anomalies observed in the Tokai area and a possible relationship with slow slips"}]},{"@id":"https://cir.nii.ac.jp/crid/2051996267021996928","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Gravity variation around Shinmoe-dake volcano from February 2011 through March 2012 : results of continuous absolute gravity observation and repeated hybrid gravity measurements"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1029/97gl00217"},{"@type":"OPENAIRE","@value":"doi_dedup___::bdfef6a3266096793af679003f08abc7"},{"@type":"CROSSREF","@value":"10.1088/0957-0233/23/4/042001_references_DOI_KT7dVXC2fjp5qZUncYfk6xvZYmf"},{"@type":"CROSSREF","@value":"10.1186/s40623-023-01901-9_references_DOI_KT7dVXC2fjp5qZUncYfk6xvZYmf"},{"@type":"CROSSREF","@value":"10.1186/bf03352203_references_DOI_KT7dVXC2fjp5qZUncYfk6xvZYmf"},{"@type":"CROSSREF","@value":"10.1186/s40623-018-0797-5_references_DOI_KT7dVXC2fjp5qZUncYfk6xvZYmf"},{"@type":"CROSSREF","@value":"10.5047/eps.2013.03.014_references_DOI_KT7dVXC2fjp5qZUncYfk6xvZYmf"},{"@type":"CROSSREF","@value":"10.21203/rs.3.rs-2740378/v1_references_DOI_KT7dVXC2fjp5qZUncYfk6xvZYmf"},{"@type":"CROSSREF","@value":"10.1186/s40623-025-02153-5_references_DOI_KT7dVXC2fjp5qZUncYfk6xvZYmf"},{"@type":"CROSSREF","@value":"10.2183/pjab.96.005_references_DOI_KT7dVXC2fjp5qZUncYfk6xvZYmf"}]}
