So far, its exact extent has not yet been established. Thanks to better bathymetric coverage and a specially adapted filtering method, we present here a new, complete, and precise mapping of the superswell. We show that the superswell covers a region broader than previously expected. It extends between latitudes 10°N and 30°S and longitudes 130°W and 160°W and has a maximum amplitude of 680 m. It is composed of two branches that display different characteristics when compared to other geophysical observations. Under the southern branch a dip in the geoid is observed which could be linked to upwelling in a convective mantle where the low‐velocity zone is located immediately below the lithosphere as indicated by tomography models. Under the northern branch, there is a 12 m high in the geoid surface anomaly that may be explained by isostatic compensation of a mass deficiency located in the mantle at 300 km depth. The northern branch could also be related to another superplume that is now going down but which was rising up 30–90 m.y. ago, when it initiated the secondary plumes which created the Line Islands.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381981469972233857","@type":"Researcher","foaf:name":[{"@value":"Claudia Adam"}],"jpcoar:affiliationName":[{"@value":"Laboratoire de Géosciences Marines Institut de Physique du Globe  Paris France"}]},{"@id":"https://cir.nii.ac.jp/crid/1381981469972233856","@type":"Researcher","foaf:name":[{"@value":"Alain Bonneville"}],"jpcoar:affiliationName":[{"@value":"Laboratoire de Géosciences Marines Institut de Physique du Globe  Paris France"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"01480227"}],"prism:publicationName":[{"@value":"Journal of Geophysical Research: Solid Earth"}],"dc:publisher":[{"@value":"American Geophysical Union (AGU)"}],"prism:publicationDate":"2005-09","prism:volume":"110","prism:number":"B9","prism:startingPage":"B09408"},"reviewed":"false","dc:rights":["http://onlinelibrary.wiley.com/termsAndConditions#vor"],"url":[{"@id":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1029%2F2004JB003465"},{"@id":"https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/2004JB003465"}],"createdAt":"2005-09-19","modifiedAt":"2023-10-12","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360004229805970176","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Electromagnetic evidence for volatile‐rich upwelling beneath the society hotspot, French Polynesia"}]},{"@id":"https://cir.nii.ac.jp/crid/1360283691684285312","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"South Pacific mantle plumes imaged by seismic observation on islands and seafloor"}]},{"@id":"https://cir.nii.ac.jp/crid/1360567179759354624","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Mantle plumes beneath the South Pacific superswell revealed by finite frequency <i>P</i> tomography using regional seafloor and island data"}]},{"@id":"https://cir.nii.ac.jp/crid/1360846639280008064","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Seismic azimuthal anisotropy in the oceanic lithosphere and asthenosphere from broadband surface wave analysis of OBS array records at 60 Ma seafloor"}]},{"@id":"https://cir.nii.ac.jp/crid/1390282679215270912","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Ocean Island Basalts in Polynesia, South Pacific"},{"@language":"ja","@value":"南太平洋，ポリネシアの海洋島玄武岩"},{"@value":"The 100s : Significant Exposures of the World(No. 9)Ocean Island Basalts in Polynesia, South Pacific : Products of Magmatism Caused by Superplume Activity"}]},{"@id":"https://cir.nii.ac.jp/crid/1390282679530316672","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Origin of hotspots in the South Pacific: Recent advances in seismological and geochemical models"}]},{"@id":"https://cir.nii.ac.jp/crid/1390285300179409792","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Broadband Ocean Bottom Seismology in Japan"},{"@language":"ja","@value":"日本の広帯域海底地震学"},{"@language":"ja-Kana","@value":"ニホン ノ コウタイイキ カイテイ ジシンガク"}]},{"@id":"https://cir.nii.ac.jp/crid/2051151842099392384","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Upper mantle structure beneath the Society hotspot and surrounding region using broadband data from ocean floor and islands"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1029/2004jb003465"},{"@type":"CROSSREF","@value":"10.1002/2016gl071331_references_DOI_DafpPnExyu0UqXoBknXA1fRlhrr"},{"@type":"CROSSREF","@value":"10.1186/s40623-016-0408-2_references_DOI_DafpPnExyu0UqXoBknXA1fRlhrr"},{"@type":"CROSSREF","@value":"10.2343/geochemj.2.0229_references_DOI_DafpPnExyu0UqXoBknXA1fRlhrr"},{"@type":"CROSSREF","@value":"10.1029/2009gc002533_references_DOI_DafpPnExyu0UqXoBknXA1fRlhrr"},{"@type":"CROSSREF","@value":"10.5026/jgeography.122.539_references_DOI_DafpPnExyu0UqXoBknXA1fRlhrr"},{"@type":"CROSSREF","@value":"10.1002/2016gl070793_references_DOI_DafpPnExyu0UqXoBknXA1fRlhrr"},{"@type":"CROSSREF","@value":"10.1002/2015jb012429_references_DOI_DafpPnExyu0UqXoBknXA1fRlhrr"},{"@type":"CROSSREF","@value":"10.4294/zisin.2019-6_references_DOI_DafpPnExyu0UqXoBknXA1fRlhrr"}]}
