Variabilidad milenaria registrada por la fauna bentónica en el Golfo de León (Mediterráneo noroccidental) entre los eventos Heinrich 3 y 4
Variations in the benthic foraminifer assemblage have been studied from a 300m-depth core in the Gulf of Lions (PRGL1-4) during the last 41-28 kyr (between Heinrich events 4 and 3). The number of benthic foraminifers per gram, the infaunal/epifaunal ratio, and most of the benthic species relative ab...

| description |
Variations in the benthic foraminifer assemblage have been studied from a 300m-depth core in the Gulf of Lions (PRGL1-4) during the last 41-28 kyr (between Heinrich events 4 and 3). The number of benthic foraminifers per gram, the infaunal/epifaunal ratio, and most of the benthic species relative abundance show a very clear Dansgaard-Oeschger variability. The stadial species suggest a well oxygenated oligotrophic environment with low organic matter content in the sediment. By contrast, the interstadial assemblage implies a more eutrophic environment with high organic matter and low oxygen content. No relevant differences are observed in the benthic fauna between Heinrich events and the other stadials |
