Biomarker records in sediment core MD99-2272 from North of Iceland Shelf

We present a sea-ice record back to 15 ka (cal. ka BP) based on the sea-ice biomarker IP25, phytoplankton biomarker brassicasterol and terrestrial biomarker long-chain...本研究基于海冰生物标志物IP25、浮游植物生物标志物菜籽甾醇（brassicasterol）以及陆地生物标志物长链……，构建了可追溯至距今15个校准千年（cal. ka BP）的海冰记录。
