Description:
This dataset includes concentration and accumulation rates of highly branched isoprenoid and sterols of Core MSM12/2-05-01 from the eastern Labrador Sea. Here, we show the records representing the last 50 ka. IP25 indicates sea ice algae production. Dinosterol and brassicasterol indicate open-water phytoplankton productivity.
