Successful culturing of deep-sea benthic foraminifera is still a relatively new field, even though Bruce Corliss published a Spotlight in PALAIOS in 1993 (Corliss, 1993) in which he stressed the potential of culturing deep-sea benthic foraminifera to refine paleoenvironmental reconstructions. In general, foraminiferal-based reconstructions of past ocean circulation and climate rely on empirical calibrations in the modern ocean, which are then extrapolated into the past. Although most calibrations of foraminiferal proxy records have been carried out using core-top sediments, in recent years laboratory culturing studies have made significant contributions to our knowledge of the controls on foraminiferal shell...
