Variations in the benthic foraminifer assemblage have been studied from a 300m-depth core in the Gulf ofLions (PRGL1-4) during the last 41-28 kyr (between Heinrich events 4 and 3). The number of benthicforaminifers per gram, the infaunal/epifaunal ratio, and most of the benthic species relative abundanceshow a very clear Dansgaard-Oeschger variability. The stadial species suggest a well oxygenated oligotrophicenvironment with low organic matter content in the sediment. By contrast, the interstadial assemblageimplies a more eutrophic environment with high organic matter and low oxygen content. No relevantdifferences are observed in the benthic fauna between Heinrich events and the other stadials. 2009-02-04 2009-10-07 2009-10-07 2007 info:eu-repo/semantics/article info:eu-repo/semantics/article González-Mora, B., Sierro Sánchez, F.
