In this work, the evolution of oceanographic parameters from 812 to\n530\u2009ka (MIS20\u2013MIS14) is studied based on the analysis of planktonic\nforaminifer assemblages from site IODP-U1385 (37\u221834.285\u2032\u2009N, 10\u22187.562\u2032\u2009W; 2585\u2009m\u2009b.s.l.).\nBy comparing the obtained results with published records from other\nNorth Atlantic sites between 41 and 55\u2218\u2009N, basin-wide\npaleoceanographic conditions are reconstructed. Variations of assemblages\ndwelling in different water masses indicate a major change in the general\nNorth Atlantic circulation during MIS16, coinciding with the definite\nestablishment of the 100\u2009ky cyclicity associated with the mid-Pleistocene\ntransition. At the surface, this change consisted in the redistribution of water\nmasses, with the subsequent thermal variation, and occurred linked to the\nnorthwestward migration of the Arctic Front (AF), and the increase in the\nNorth Atlantic Deep Water (NADW) formation with respect to previous glacials.\nDuring glacials prior to MIS16, the NADW formation was very weak, which\ndrastically slowed down the surface circulation; the AF was at a southerly\nposition and the North Atlantic Current (NAC) diverted southeastwards,\ndeveloping steep south\u2013north, and east\u2013west, thermal gradients and blocking\nthe arrival of warm water, with associated moisture, to high latitudes.\nDuring MIS16, the increase in the meridional overturning circulation, in\ncombination with the northwestward AF shift, allowed the arrival of the NAC\nto subpolar latitudes, multiplying the moisture availability for ice-sheet\ngrowth, which could have worked as a positive feedback to prolong the\nglacials towards 100\u2009ky cycles.<\/jats:p>","DOI":"10.5194\/cp-14-1639-2018","type":"journal-article","created":{"date-parts":[[2018,11,7]],"date-time":"2018-11-07T07:11:40Z","timestamp":1541574700000},"page":"1639-1651","source":"Crossref","is-referenced-by-count":9,"title":["Change in the North Atlantic circulation associated with the mid-Pleistocene transition"],"prefix":"10.5194","volume":"14","author":[{"given":"Gloria M.","family":"Martin-Garcia","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8647-456X","authenticated-orcid":false,"given":"Francisco J.","family":"Sierro","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1909-293X","authenticated-orcid":false,"given":"Jos\u00e9 A.","family":"Flores","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9110-0212","authenticated-orcid":false,"given":"F\u00e1tima","family":"Abrantes","sequence":"additional","affiliation":[]}],"member":"3145","published-online":{"date-parts":[[2018,11,7]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","unstructured":"Adkins, J.: The role of deep ocean circulation in setting glacial climates,\nPaleoceanography, 28, 539\u2013561, 2013.","DOI":"10.1002\/palo.20046"},{"key":"ref2","doi-asserted-by":"crossref","unstructured":"Adkins, J.
