Seamounts are abundant and prominent features on the deep-sea floor and\nintersperse with the nodule fields of the Clarion-Clipperton Fracture Zone\n(CCZ). There is a particular interest in characterising the fauna inhabiting\nseamounts in the CCZ because they are the only other ecosystem in the region\nto provide hard substrata besides the abundant nodules on the soft-sediment\nabyssal plains. It has been hypothesised that seamounts could provide refuge\nfor organisms during deep-sea mining actions or that they could play a role\nin the (re-)colonisation of the disturbed nodule fields. This hypothesis is\ntested by analysing video transects in both ecosystems, assessing megafauna\ncomposition and abundance. Nine video transects (ROV dives) from two different license areas and one\nArea of Particular Environmental Interest in the eastern CCZ were analysed.\nFour of these transects were carried out as exploratory dives on four\ndifferent seamounts in order to gain first insights into megafauna\ncomposition. The five other dives were carried out in the neighbouring\nnodule fields in the same areas. Variation in community composition observed\namong and along the video transects was high, with little morphospecies\noverlap along intra-ecosystem transects. Despite the observation of\nconsiderable faunal variations within each ecosystem, differences between\nseamounts and nodule fields prevailed, showing significantly different\nspecies associations characterising them, thus calling into question their use as a\npossible refuge area.<\/jats:p>","DOI":"10.5194\/bg-17-2657-2020","type":"journal-article","created":{"date-parts":[[2020,5,15]],"date-time":"2020-05-15T11:39:26Z","timestamp":1589542766000},"page":"2657-2680","source":"Crossref","is-referenced-by-count":31,"title":["Are seamounts refuge areas for fauna from polymetallic nodule fields?"],"prefix":"10.5194","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4042-8215","authenticated-orcid":false,"given":"Daphne","family":"Cuvelier","sequence":"first","affiliation":[]},{"given":"Pedro A.","family":"Ribeiro","sequence":"additional","affiliation":[]},{"given":"Sofia P.","family":"Ramalho","sequence":"additional","affiliation":[]},{"given":"Daniel","family":"Kersken","sequence":"additional","affiliation":[]},{"given":"Pedro","family":"Martinez Arbizu","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6462-5670","authenticated-orcid":false,"given":"Ana","family":"Cola\u00e7o","sequence":"additional","affiliation":[]}],"member":"3145","published-online":{"date-parts":[[2020,5,15]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","unstructured":"Amon, D.
