Abstract:
These datasets contain the age model, Summer Sea Surface Temperature reconstruction (SSST), relative percentage of planktonic foraminifera and diatoms and their associated standard error from core MD07-3081. This core was collected ~100 km from the coast of Chile with a CALYPSO piston corer during the oceanographic expedition MD159 PACHIDERME onboard R/V Marion Dufresne and covers the period from the Last Glacial Maximum to the Late Holocene. They present a new paleoceanographic reconstruction since the Last Glacial Maximum, at 49º S in the Pacific Ocean, an environment in which diatoms have not been studied previously.
