Abstract

• The environment of the central Mediterranean Sea is investigated on the basis of high-resolution planktonic foraminifera and calcareous nannofossil data (mean sampling resolutions of about 80 and 160 yr, respectively). MIS 5 is characterized by warm, oligotrophic and stratified waters, while coccolithophore communities developed a vertical zonation that, in today's oceans, is typical of the low-latitude gyres. The temperate-subtropical configuration of planktonic foraminifera and calcareous nannofossil assemblages is repeatedly transformed into a temperate-subpolar one during the suborbital cooling episodes C25-C18. A comparison with European pollen sequences and North Atlantic cores over the interval between about 128 and 110 kyr BP is carried out. Records from this broad geographical area show a series of environmental changes that occurred at comparable times. However, the first cooling episodes were more severe at high-latitude (approximately north of 50°N), where an anticipated end of interglacial conditions can be ascribed. Variations in the rate of the Atlantic meridional overturning circulation and the strength of atmospheric circulation in the Northern Hemisphere are discussed as likely climatic forcing mechanisms.

• L'environnement de la Méditerranée Centrale durant le dernier Interglaciaire est reconstitué à partir de l'étude à haute résolution des foraminifères planctoniques et des nannofossiles calcaires (résolution moyenne des échantillons d'environ 80 et 160 ans respectivement). MIS 5 est caractérisé par des eaux chaudes, oligotrophes et stratifiées, tandis que les communautés de coccolithophoridés développent une zonation verticale qui, dans les océans actuels, est typique des gyres de basse latitude. La configuration tempérée-subtropicale des foraminifères planctoniques et des assemblages de nannofossiles calcaires passe de façon répétée à une configuration tempérée-subpolaire durant les épisodes froids suborbitaux C25-C18. Une comparaison avec les séquences polliniques carottées en Europe et en Atlantique Nord sur l'intervalle 128-110 ka est effectuée. Les enregistrements obtenus sur ces séquences et en Méditerranée Centrale témoignent d'une série de changements environnementaux contemporains. Cependant, les premiers épisodes froids sont plus sévères aux hautes-latitudes (au nord de la latitude 50°N), laissant supposer une fin plus précoce des conditions climatiques interglaciaires. Les variations de la « Meridional Overturning circulation » (MOC) ou « tapis roulant » de l'Atlantique et l'intensité de la circulation atmosphérique dans l'Hémisphère Nord sont discutées comme un des mécanismes possibles de forçage climatique.
