Surface ocean temperatures in the north‐east Atlantic during the last 500 000 years: evidence from foraminiferal census data
Abstract Changes in North Atlantic sea surface temperature (SST) are regarded as a key element of the climate during the Quaternary. However, there are relatively few long‐term records providing quantitative SST estimates from this region. Using planktic foraminiferal‐derived SSTs together with chan...
