Abstract:

The data set contains paleoenvironmental reconstructions from core AMK-6150 (Norwegian Sea) that covers the last 2900 years. Paleoreconstructions include dinocyst-based summer and winter sea-surface salinity (SSS), temperature (SST) and sea-ice cover (SIC), sea-subsurface temperature (SSbT) based on planktic foraminifera and august sea-surface temperature (aSST) based on diatoms.
