Description
The authors obtained high-resolution (22-year average) planktonic foraminiferal Mg/Ca and stable oxygen isotope (δ18O) data from a pair of sediment cores retrieved from the northeast Atlantic Ocean's Feni Drift, Rockall Trough region (5539.02'N, 1359.10'W and 5539.10'N, 1359.13'W) from which they derived late-Holocene (0-2.4 ka BP) sea surface temperatures (SSTs). This work revealed the MWP to have occurred between approximately AD 750 and 1160; and a plot of the results (shown below) reveals the peak temperature of the MWP to have been about 2.3C greater than the peak temperature of the late 20th century.
