Abstract:
Winter mixed layer depth (MLD) was reconstructed from the dinocyst assemblage data of sediment core HU90-013-013 using two different approaches: modern analogue technique (MAT) and weighted averaging partial least square (WAPLS) regression and calibration. The n = 1968 modern dinocyst database and the modern MLD climatology of 1981-2010 from the World Ocean Atlas 2018 were used as calibration dataset.
