Climate reconstruction of the MWP in the Baltic Sea area based on biogeochemical proxies from a sediment record
A multi-proxy data set from a sediment core from the Central Gotland Basin shows an extreme peak in many variables in a depth of 70-80 cm. Dating suggests an age of 700-790 varve years (before 1950) which fits into the Medieval Warm Period (MWP) from 1100-1250 AD. The variables are used as regional...

A multi-proxy data set from a sediment core from the Central Gotland Basin shows an extreme peak in many variables in a depth of 70-80 cm.
