Biomarker analyses on sediment core BP00-07/07 from the southern Kara Sea (Arctic Ocean) ...
The Holocene is characterized by the late Holocene cooling trend as well as by internal short-term centennial fluctuations. As Arctic sea ice acts as a significant component (amplifier) within the climate system, investigating its past long- and short-term variability and controlling processes is be...
