Sea Surface Temperature estimates and benthic foraminifera stable isotopes from IODP 1406 over the Oligocene Miocene time interval
Here, we present a new record of SST for the time interval 30 to 17 Ma derived from the long‐chain alkenone unsaturation ratio uk'37 and TEX 86 at Integrated Ocean Drilling Program Site 1406A in the midlatitude North Atlantic. Results confirm that warm temperatures from 24°C to over 30°C prevai...
