This paper shows evidence of the natural dynamics of <i>P. oceanica</i> “shifting intermattes” or “sand corridors” (hereafter SCs): unvegetated patches within a dense meadow. We studied features and temporal evolution (2001-2015) of 5 SCs in the Calvi Bay (Corsica) at 15 m depth and followed the characteristics the <i>P. oceanica</i> meadow lining the edge of patches. All SCs show a similar topography. The eroded side is a vertical edge where roots, rhizomes and sediments are visible, when on the opposite colonized side, the sand is at the same level as the continuous meadow. The vertical edge reaches a maximum height of 160 cm and is eroded by orbital bottom currents with a maximum speed of 12 cm.s<sup>-1</sup>, the erosion speed ranging from 0.6 to 15 cm.y<sup>-1</sup>. SCs progress toward the coastline with a mean speed of 10 cm.y<sup>-1</sup>, the rate of colonization by <i>P. oceanica</i> shoots ranging from 1.5 to 21 cm.y<sup>-1</sup>. We calculated that the studied SCs would reach the coastline within 500 to 600 years. We finally discuss the implication of such dynamic in the framework of meadows’ colonization assessment and the seascape dynamic.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Temporal evolution of sand corridors in a <i>Posidonia oceanica</i> seascape: a 15-year study","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-05 01:31:09.096169","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Seagrass colonization; Posidonia oceanica dynamics; Intermatte;Mediterranean Sea; Seascape","OtherDescriptors":null,"Notes":null,"AnaPub":2016,"MonPub":null,"DateUpdate":"2017-05-18","DateCreate":"2017-05-16","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000392316700016","VABBcode":null,"OpenAcc":1,"DOI":"10.12681/mms.1816"},"refs":null,"anarec":{"AnaID":285675,"PubliDate":2016,"Pagination":"777-784","XtraPublOfAnaID":null,"ISBN":null,"Volume":"17","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44165,"SerRR":"Mediterranean Marine Science.
