Deep-water temperatures from the Southern Ocean during HS4 ...
Foraminiferal magnesium to calcium ratios (Mg/Ca) are reported for two benthic species, drawn from down-core marine sediment samples obtained from the deep Southern Ocean. Samples of 4-10 individual benthic foraminifera, of the species Globobulimina affinis and/or Uvigerina sp., were oxidatively cle...
