Description
Lund and Curry reconstructed surface temperatures of the Florida Current near the Great Bahama Bank (24°45.5'N, 79°17.5'W) from Mg/Ca measurements of the fossil shells of the surface-dwelling foraminifer Globigerinoides rubber found in a sediment core taken from a depth of approximately 700 meters. This work indicated that the peak surface temperature of the MWP (AD 740-880) was approximately 0.25°C greater than that of the upper segment of the core, which was deposited "primarily after AD 1950."
