Each SST estimate was calculated as the mean of the best 10 analogues from the global database. Statement: Sea-surface temperatures (SST) were estimated from planktonic foraminifera assemblage data. This has been collected for every 5cm of the core. The most precise variable of SST is mean annual temperature, followed by Tmax, then Tmin. All variables have a root mean squared error of prediction of less than 1 degree C. Most of the SST estimates are reasonably precise, given that the samples have good analogues in the AUSMAT-F4 database. Estimates do however become a little less precise towards the end of the core in MIS 3 (~30k BP). Parameters: Age of core (yrs BP), mean water temperature (oC), maximum water temperature (oC), minimum water temperature (oC), depth of mixed layer (m), temperature at 50m, 100m and 150m (oC).
