Sea-surface conditions estimated from dinocyst assemblages in sediment core AMD0509-20

The summer sea-surface temperature and salinity, the seasonal duration of sea-ice cover, and the mean annual productivity were estimated based on the modern analogue technique applied to dinocyst data. The most probable estimates (weighted average of values from the 5 best analogues) are given in the table. The data are reported vs depth and vs ages calibrated based on Marine20.
