Palanques, Albert European Commission Generalitat de Catalunya Ministerio de Economía y Competitividad (España) Sedimentation rates Fishing effort Bottom trawling Submarine canyons 9 pages, 7 figures, 1 table Commercial bottom trawling causes some of the largest impacts on the sea floor, and it has been identified as one of the major drivers of sediment resuspension on continental slope regions, particularly in areas surrounding submarine canyons. To assess whether there have been significant trawling-induced alterations in the sediment dynamics within the Foix Canyon (Northwestern Mediterranean) during the past century, sediment accumulation rates obtained using Pb and Cs radiochronology were compared between sediment cores retrieved in 1993 and in 2013 from the canyon axis at 860 m depth. The results indicate an almost two-fold increase in the sedimentation rate in the 1960–70s, from 0.5 cm·y to 0.9 cm·y, as a consequence of the rapid industrialization of the fishing sector at that time. Sedimentation rates further doubled to 1.8 cm·y in the early 2000s. This period was characterized by the construction of bigger trawlers with more powerful engines as well as the modernization of the engines of existing vessels, all of which were largely under-declared. These results provide compelling evidence of the increasing impact of bottom trawling due to the modernization of trawling fleets at the beginning of the XXI century This research has been supported by PERSEUS (GA 287600) European grants, by FORMED (CGL2012-33989) and ABIDES (CTM2015-65142-R) Spanish grants, by the Generalitat de Catalunya supporting grants 2014 SGR-1642 and 2014 SGR-1356, as well as a predoctoral F.P.U. grant from the Spanish government Peer Reviewed 2018-05-30T06:52:35Z 2018-05-30T06:52:35Z 2018-02 2018-05-30T06:52:35Z artículo http://purl.org/coar/resource_type/c_6501 issn: 0967-0637 e-issn: 1879-0119 Deep-Sea Research Part I: Oceanographic Research Papers 132: 51-59 (2018) http://hdl.handle.net/10261/165293 10.1016/j.dsr.2018.01.002 http://dx.doi.org/10.13039/501100002809 http://dx.doi.org/10.13039/501100000780 http://dx.doi.org/10.13039/501100003329 #PLACEHOLDER_PARENT_METADATA_VALUE# #PLACEHOLDER_PARENT_METADATA_VALUE# info:eu-repo/grantAgreement/MINECO/Plan Estatal de Investigación Científica y Técnica y de Innovación 2013-2016/CTM2015-65142-R info:eu-repo/grantAgreement/EC/FP7/287600 https://doi.org/10.1016/j.dsr.2018.01.002 Sí none Pergamon Press
