A record of bottom water temperature and seawater [delta] 18O for the Southern Ocean over the past 440 kyr based on Mg/Ca of benthic foraminiferal Uvigerina spp.
Description: The sensitivity to temperature of Mg/Ca ratios in the shallow-infaunal benthic foraminifera Uvigerina spp. has been assessed. Analysis reveals a 2.5-kyr lead in the record of temperature over calcite δ(18)O and a longer lead over seawater δ(18)O. This is a reflection of larger phase offsets at eccentricity periods; phase offsets at tilt and precession are within error zero. [Source: Quaternary Science Reviews]
