These records have contributed to our understanding of Earth's magnetic field and are the foundation of the Geomagnetic Instability Time Scale (GITS) in the Quaternary. Here, we present the magnetostratigraphy from Sites U1555 (0 to similar to 2.7 Ma) and U1563 (0 to similar to 5.2 Ma) drilled during the International Ocean Discovery Program Expedition 395C on the eastern side of the modern Mid-Atlantic Ridge (similar to 60 degrees N, 20-30 degrees W). Shipboard paleomagnetic and microfossil data provided a preliminary age model, extending the regional record to 3.4 Ma. The Virtual Geomagnetic Pole latitudes from archive halves, corroborated with data from discrete samples, were used to build a high-resolution magnetostratigraphy, which contained the expected Brunhes and Matuyama Chrons and their respective Subchrons. We also identified most of the magnetic events reported in the GITS, including the less well-documented ones, such as Osaka, Kamitzukara, Huckleberry Ridge, Reunion, Gardar, Halawa and L4 events. The high-resolution magnetostratigraphy from Sites U1555 and U1563 is compared with two previous legacy sites and contributes toward an increasingly robust GITS, expanding its use as a correlation and dating tool.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Geomagnetic Excursions Recorded in North Atlantic IODP Expedition 395C Sites U1555 and U1563","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-10-11 01:33:38.116610","timezone_type":1,"timezone":"+02:00"},"AuthorKeywords":"Bruhnes;Matuyama;magnetostratigraphy;excursions;paleomagnetism;magnetic instabilities;International Ocean Discovery Program;Site U1555;Site U1563;Expedition 395C;matuyama-brunhes boundary;faunal extinctions;field;drift;paleointensity;reversals;evolution;bjorn;ages","OtherDescriptors":null,"Notes":null,"AnaPub":2025,"MonPub":null,"DateUpdate":"2026-09-28","DateCreate":"2026-09-28","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:001510685300001","VABBcode":null,"OpenAcc":0,"DOI":"10.1029/2025GC012220"},"refs":null,"anarec":{"AnaID":449243,"PubliDate":2025,"Pagination":"e2025GC012220","XtraPublOfAnaID":null,"ISBN":null,"Volume":"26","Issue":"6","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":100768,"SerRR":"Geochemistry, Geophysics, Geosystems.
