In this study, we present a multidisciplinary, non-intrusive downscale approach for the documentation of UCH implemented on the coastal area of Aegina Island, Greece, where a unique submerged harbour complex is preserved. This approach succeeded in obtaining information that serves both geomorphological and archaeological purposes in a time- and cost-effective way, while obtaining information of centimeters to millimeters scale. The geomorphology of the area was mapped in detail through marine geophysical means while ancient submerged conical rubble structures and breakwaters were documented using automatic seafloor segmentation techniques, revealing previously unknown sites of archaeological interest. The structures\u2019 parameters were extracted from the acoustic data to analyze their morphometry, while photogrammetry was realized using a Remotely Operated Vehicle to expose their micro-structure. The spatial distribution of the structures revealed the construction of a well-planned harbour complex with multiple passages and different possible functionalities. Finally, through the structures\u2019 morphometric analysis (geometry and terrain statistical parameters) their preservation status was revealed, demonstrating the anthropogenic impact on the submerged ancient structures due to the modern harbor activity.<\/jats:p>","DOI":"10.3390\/rs13214462","type":"journal-article","created":{"date-parts":[[2021,11,7]],"date-time":"2021-11-07T20:42:54Z","timestamp":1636317774000},"page":"4462","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["A Multidisciplinary Approach for the Mapping, Automatic Detection and Morphometric Analysis of Ancient Submerged Coastal Installations: The Case Study of the Ancient Aegina Harbour Complex"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7544-6814","authenticated-orcid":false,"given":"Nikos","family":"Georgiou","sequence":"first","affiliation":[{"name":"Laboratory of Marine Geology and Physical Oceanography, Department of Geology, University of Patras, 265 00 Rio Patras, Greece"}]},{"given":"Xenophon","family":"Dimas","sequence":"additional","affiliation":[{"name":"Laboratory of Marine Geology and Physical Oceanography, Department of Geology, University of Patras, 265 00 Rio Patras, Greece"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3290-5467","authenticated-orcid":false,"given":"Elias","family":"Fakiris","sequence":"additional","affiliation":[{"name":"Laboratory of Marine Geology and Physical Oceanography, Department of Geology, University of Patras, 265 00 Rio Patras, Greece"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3012-6865","authenticated-orcid":false,"given":"Dimitris","family":"Christodoulou","sequence":"additional","affiliation":[{"name":"Laboratory of Marine Geology and Physical Oceanography, Department of Geology, University of Patras, 265 00 Rio Patras, Greece"}]},{"given":"Maria","family":"Geraga","sequence":"additional","affiliation":[{"name":"Laboratory of Marine Geology and Physical Oceanography, Department of Geology, University of Patras, 265 00 Rio Patras, Greece"}]},{"given":"Despina","family":"Koutsoumpa","sequence":"additional","affiliation":[{"name":"Ephorate of Underwater Antiquities, Hellenic Ministry of Culture and Sports, 117 42 Athens, Greece"}]},{"given":"Kalliopi","family":"Baika","sequence":"additional","affiliation":[{"name":"Centre Camille Jullian, Aix Marseille Univ, CNRS, 13090 Aix-en-Provence, France"}]},{"given":"Pari","family":"Kalamara","sequence":"additional","affiliation":[{"name":"Ephorate of Underwater Antiquities, Hellenic Ministry of Culture and Sports, 117 42 Athens, Greece"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4151-7909","authenticated-orcid":false,"given":"George","family":"Ferentinos","sequence":"additional","affiliation":[{"name":"Laboratory of Marine Geology and Physical Oceanography, Department of Geology, University of Patras, 265 00 Rio Patras, Greece"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3732-1900","authenticated-orcid":false,"given":"George","family":"Papatheodorou","sequence":"additional","affiliation":[{"name":"Laboratory of Marine Geology and Physical Oceanography, Department of Geology, University of Patras, 265 00 Rio Patras, Greece"}]}],"member":"1968","published-online":{"date-parts":[[2021,11,6]]},"reference":[{"key":"ref_1","unstructured":"(2021, August 05).
