DESCRIPTION:The study of fossil foraminifera goes back to the early 19th c
 entury\, making them one of the best studied microfossil groups. More rece
 ntly\, our increasing understanding of their distribution and ecological r
 equirements in the present-day oceans has made the quantitative evaluation
  of foraminiferal assemblages a powerful means of actualistic paleoenviron
 mental reconstruction.\nIn this paper I present examples for the applicati
 on of benthic foraminiferal assemblages from IODP Site U1385 (“Shackleto
 n Site”) as proxies of paleoceanographic Change in the Pleistocene NE At
 lantic.  A brief introduction to the present-day distribution of benthic f
 oraminifera in the area and the relation to the oceanographic setting is f
 ollowed by an evaluation of differences between the present-day situation 
 and major glacial/interglacial transitions. The presentation is wrapped up
  by a discussion of the implications of observed turnovers in the benthic 
 foraminiferal fauna for changes of sea-water properties at the water/sedim
 ent interface during these rapid climatic transitions.
