According to this configuration, some studies (e.g. Raymo et al., 2006) predicts a +20 m eustatic sea-level rise for this time interval, reflecting significant retreat of some combination of the West Antarctic Ice Sheet, marginal East Antarctic ice, and the Greenland Ice Sheet, and consequently significant variations in the ocean and climate dynamics at global scale.In this study we show data of variability in the coccolithophore assemblage from IODP Site 1385 (Shackleton Site, IODP 339 and IODP 397) in the interval ca. 1 Ma (close to the Jaramillo event). These sediments are sensitive recorders of North Atlantic Deep Water (NADW) and Antarctic Bottom Water (AABW) oscillations, which makes this site a significant location to test the interhemispheric connection hypotheses.Peaks in abundance of Gephyrocapsa (<\/jats:p>","DOI":"10.5194\/egusphere-egu24-15648","type":"posted-content","created":{"date-parts":[[2024,3,9]],"date-time":"2024-03-09T03:12:10Z","timestamp":1709953930000},"source":"Crossref","is-referenced-by-count":0,"title":["Paleoproductivity and surface water dynamics evolution during the MIS 31 in the Shackleton Site as revealed Coccolithophores"],"prefix":"10.5194","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1909-293X","authenticated-orcid":false,"given":"Jose-Abel","family":"Flores","sequence":"first","affiliation":[]},{"given":"Barbara","family":"Balestra","sequence":"additional","affiliation":[]},{"given":"William","family":"Clark","sequence":"additional","affiliation":[]},{"given":"Francisco Jos\u00e9","family":"Jim\u00e9nez-Espejo","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2218-4854","authenticated-orcid":false,"given":"Junichiro","family":"Kuroda","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1000-2977","authenticated-orcid":false,"given":"Emilia","family":"Salgueiro","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7391-5768","authenticated-orcid":false,"given":"Joan","family":"Grimalt","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1556-4290","authenticated-orcid":false,"given":"Timothy","family":"Herbert","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8261-2286","authenticated-orcid":false,"given":"Maria Angeles","family":"B\u00e1rcena","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9110-0212","authenticated-orcid":false,"given":"Fatima","family":"Abrantes","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8537-1588","authenticated-orcid":false,"given":"David","family":"Hodell","sequence":"additional","affiliation":[]},{"given":"Carlos","family":"Alvarez Zarikian","sequence":"additional","affiliation":[]},{"given":"Expedition","family":"397 Scientific Party","sequence":"additional","affiliation":[]}],"member":"3145","container-title":[],"original-title":[],"deposited":{"date-parts":[[2025,1,20]],"date-time":"2025-01-20T12:04:58Z","timestamp":1737374698000},"score":1,"resource":{"primary":{"URL":"https:\/\/meetingorganizer.copernicus.org\/EGU24\/EGU24-15648.html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,1,20]]},"references-count":0,"URL":"https:\/\/doi.org\/10.5194\/egusphere-egu24-15648","relation":{},"subject":[],"published":{"date-parts":[[2025,1,20]]},"subtype":"other"}}
