(Table 2) Age determination of sediment cores from the Tasman Plateau ...
Various biomarkers (n-alkanes, n-alcohols, and sterols) have been studied in a piston core TSP-2PC taken from the Southern Ocean to reconstruct the paleoenvironmental changes in the subantarctic region for the last two deglaciations. Mass accumulation rates of terrestrial (higher molecular weight n-...
