Periodic sediment sampling using a Van Veen grab was performed using an adaptative sampling grid that accounted for tracer&amp;amp;#8217;s dispersion trough time. The samples were washed and dried in laboratory and tagged particles were automatically identified using an automated image analysis procedure based on ultraviolet lighting.&amp;lt;\/p&amp;gt;&amp;lt;p&amp;gt;Preliminary results show that sediment transport is dominated by a eastward component,probably related with the energetic events from the SW. Ongoing work relates the tracer&amp;amp;#8217;s displacement with ADCP (wave and current) data measured nearby the borrow site during the experiment.&amp;lt;\/p&amp;gt;&amp;lt;p&amp;gt;&amp;amp;#160;&amp;lt;\/p&amp;gt;&amp;lt;p&amp;gt;The authors would like to acknowledge the financial support FCT through project UIDB\/50019\/2020 &amp;amp;#8211; IDL and ECOEXA project (MAR-01.04.02-FEAMP-0016).&amp;lt;\/p&amp;gt;&amp;lt;p&amp;gt;&amp;amp;#160;&amp;lt;\/p&amp;gt;&amp;lt;p&amp;gt;&amp;amp;#160;&amp;lt;\/p&amp;gt;<\/jats:p>","DOI":"10.5194\/egusphere-egu21-15834","type":"posted-content","created":{"date-parts":[[2021,3,4]],"date-time":"2021-03-04T13:44:21Z","timestamp":1614865461000},"source":"Crossref","is-referenced-by-count":0,"title":["Monitoring inner shelf sediment transport using fluorescent sand tracers: an example from the south coast of Portugal&amp;#160;"],"prefix":"10.5194","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7831-1069","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Cascalho","sequence":"first","affiliation":[]},{"given":"Rui","family":"Taborda","sequence":"additional","affiliation":[]},{"given":"Marcos","family":"Rosa","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4584-9759","authenticated-orcid":false,"given":"Erwan","family":"Garel","sequence":"additional","affiliation":[]},{"given":"Sebasti\u00e3o","family":"Teixeira","sequence":"additional","affiliation":[]},{"given":"Ana","family":"Alberto","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3496-3270","authenticated-orcid":false,"given":"Teresa","family":"Drago","sequence":"additional","affiliation":[]}],"member":"3145","container-title":[],"original-title":[],"deposited":{"date-parts":[[2021,3,4]],"date-time":"2021-03-04T13:47:47Z","timestamp":1614865667000},"score":1,"resource":{"primary":{"URL":"https:\/\/meetingorganizer.copernicus.org\/EGU21\/EGU21-15834.html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,3,4]]},"references-count":0,"URL":"https:\/\/doi.org\/10.5194\/egusphere-egu21-15834","relation":{},"subject":[],"published":{"date-parts":[[2021,3,4]]},"subtype":"other"}}
