However, compared to onshore deposits, offshore deposits are more difficult to access, and so far, studies of outer shelf tsunami deposits are scarce. Here, an example of studying these deposits is presented to infer implications for tsunami-related signatures in similar environments and potentially contribute to pre-historic tsunami event detections. A multidisciplinary approach was performed to detect the sedimentary imprints left by the 1755 CE tsunami in two cores, located in the southern Portuguese continental shelf at water depths of 58 and 91 m. Age models based on 14C and 210Pbxs allowed a probable correspondence with the 1755 CE tsunami event. A multi-proxy approach, including sand composition, grain-size, inorganic geochemistry, magnetic susceptibility, and microtextural features on quartz grain surfaces, yielded evidence for a tsunami depositional signature, although only a subtle terrestrial signal is present. A low contribution of terrestrial material to outer shelf tsunami deposits calls for methodologies that reveal sedimentary structures linked to tsunami event hydrodynamics. Finally, a change in general sedimentation after the tsunami event might have influenced the signature of the 1755 CE tsunami in the outer shelf environment.<\/jats:p>","DOI":"10.3390\/min10090731","type":"journal-article","created":{"date-parts":[[2020,8,19]],"date-time":"2020-08-19T09:22:31Z","timestamp":1597828951000},"page":"731","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Exploring Offshore Sediment Evidence of the 1755 CE Tsunami (Faro, Portugal): Implications for the Study of Outer Shelf Tsunami Deposits"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0925-2047","authenticated-orcid":false,"given":"Vincent","family":"K\u00fcmmerer","sequence":"first","affiliation":[{"name":"CIMA\u2014Centre for Marine and Environmental Research, FCT, Universidade do Algarve, 8005-139 Faro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3496-3270","authenticated-orcid":false,"given":"Teresa","family":"Drago","sequence":"additional","affiliation":[{"name":"Instituto Portugu\u00eas do Mar e da Atmosfera, 1749-077 Lisboa, Portugal"},{"name":"Instituto Dom Luiz, Universitdade de Lisboa, 1749-016 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9323-0723","authenticated-orcid":false,"given":"Cristina","family":"Veiga-Pires","sequence":"additional","affiliation":[{"name":"CIMA\u2014Centre for Marine and Environmental Research, FCT, Universidade do Algarve, 8005-139 Faro, Portugal"}]},{"given":"Pedro F.","family":"Silva","sequence":"additional","affiliation":[{"name":"Instituto Dom Luiz, Universitdade de Lisboa, 1749-016 Lisboa, Portugal"},{"name":"Instituto Superior de Engenharia de Lisboa, Instituto Polit\u00e9cnico de Lisboa, 1959\/007 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3205-771X","authenticated-orcid":false,"given":"Vitor","family":"Magalh\u00e3es","sequence":"additional","affiliation":[{"name":"Instituto Portugu\u00eas do Mar e da Atmosfera, 1749-077 Lisboa, Portugal"},{"name":"Instituto Dom Luiz, Universitdade de Lisboa, 1749-016 Lisboa, Portugal"}]},{"given":"Anxo","family":"Mena","sequence":"additional","affiliation":[{"name":"Departamento de Xeoci\u00eancias Mari\u00f1as e Ordenaci\u00f3n do Territ\u00f3rio Universidade de Vigo, 36310 Vigo, Spain"}]},{"given":"Ana","family":"Lopes","sequence":"additional","affiliation":[{"name":"Instituto Portugu\u00eas do Mar e da Atmosfera, 1749-077 Lisboa, Portugal"},{"name":"Departamento de Geolog\u00eda, Universidad de Salamanca, 37008 Salamanca, Spain"}]},{"given":"Ana Isabel","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"Instituto Portugu\u00eas do Mar e da Atmosfera, 1749-077 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5985-9747","authenticated-orcid":false,"given":"Sabine","family":"Schmidt","sequence":"additional","affiliation":[{"name":"CNRS, Univ.
