Abstract:
This dataset includes concentration and accumulation rates of alkenone, the percentage of C37:4, and SST calculation based on the alkenone concentration of Core MSM12/2-05-01 from the eastern Labrador Sea. Here, we show the records representing the last 50 ka. The total alkenone content, %C37:4, and SSTs indicate open-water phytoplankton productivity, meltwater inflow, and sea surface temperatures, respectively.
