Total organic carbon, delta13C, biomarker, diatom distributions in sediment core JM11-FI-19PC ...
In the light of rapidly diminishing sea ice cover in the Arctic during the present atmospheric warming, it is imperative to study the distribution of sea ice in the past in relation to rapid climate change. Here we focus on glacial millennial scale climatic events (Dansgaard/Oeschger events) using t...
