Until now, active swimming motion has been derived from total motion by subtracting surface or subsurface modelled ocean currents, following the approximation of a quasi-two-dimensional surface layer migration. This study, based on tracking and diving data collected from 25 late-juvenile loggerhead turtles released from Reunion Island during their pre-reproductive migration, demonstrates the importance of considering the subsurface presence of the animals. Using a piecewise constant heading model, we investigate navigation strategy using daily time-at-depth distributions and three-dimensional currents to calculate swimming velocity. Our results are consistent with a map and compass strategy in which swimming movements follow straight courses at a stable swimming speed (approx. 0.5 m s\n            <jats:sup>\u22121<\/jats:sup>\n            ), intermittently segmented by course corrections. This strategy, previously hypothesized for post-nesting green and hawksbill turtles, had never been observed in juvenile loggerheads. These results confirm a common open-ocean navigation mechanism across ages and species and highlight the importance of considering diving behaviour in most studies of sea turtle spatial ecology.\n          <\/jats:p>","DOI":"10.1098\/rsif.2023.0383","type":"journal-article","created":{"date-parts":[[2023,12,13]],"date-time":"2023-12-13T00:05:22Z","timestamp":1702425922000},"update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":11,"title":["Uncovering loggerhead (\n            <i>Caretta caretta<\/i>\n            ) navigation strategy in the open ocean through the consideration of their diving behaviour"],"prefix":"10.1098","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2748-6429","authenticated-orcid":true,"given":"Antoine","family":"Laforge","sequence":"first","affiliation":[{"name":"Laboratoire de l'Atmosph\u00e8re et des Cyclones (UMR 8105 LACY), 15 avenue Ren\u00e9 Cassin, 97715 Saint-Denis, La R\u00e9union, France"},{"name":"Mercator Ocean International, 2 Av. de l'A\u00e9rodrome de Montaudran, 31400 Toulouse, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philippe","family":"Gaspar","sequence":"additional","affiliation":[{"name":"Mercator Ocean International, 2 Av. de l'A\u00e9rodrome de Montaudran, 31400 Toulouse, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anne","family":"Barat","sequence":"additional","affiliation":[{"name":"Laboratoire de l'Atmosph\u00e8re et des Cyclones (UMR 8105 LACY), 15 avenue Ren\u00e9 Cassin, 97715 Saint-Denis, La R\u00e9union, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julien Temple","family":"Boyer","sequence":"additional","affiliation":[{"name":"Mercator Ocean International, 2 Av. de l'A\u00e9rodrome de Montaudran, 31400 Toulouse, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tony","family":"Candela","sequence":"additional","affiliation":[{"name":"Mercator Ocean International, 2 Av. de l'A\u00e9rodrome de Montaudran, 31400 Toulouse, France"},{"name":"Upwell, Monterey, CA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u00e9r\u00f4me","family":"Bourjea","sequence":"additional","affiliation":[{"name":"MARBEC, Univ.
