Improving past sea surface temperature estimates based on planktonic fossil faunas
International audience A new method of past sea surface temperature (SST) reconstruction based on the modem analog technique (Prell, 1985) and on the indirect approach (Bartlein et al., 1986) has been developed: the revised analog method (RAM). Applied to planktonic foraminifera, this technique lead...
