The mid-Piacenzian of the North Atlantic Ocean

Here we focus on the North Atlantic region, incorporating new and existing faunal assemblage and alkenone paleotemperature data from Ocean Drilling Program Sites 642, 662, 982, and 999, and International Ocean Discovery Program Sites 1308 and 1313 into our paleoenvironmental reconstruction.

Cores and outcrop material containing Piacenzian sediments from the Atlantic Coastal Plain of Virginia, USA, are also included. These data allow us to characterize regional changes in temperature, salinity, upwelling, surface productivity, and diversity, associated with climate transitions, and make nuanced reconstructions of mid-Piacenzian conditions within a high-resolution temporal framework between similar to 3.40 and similar to 3.15Ma, inclusive of Marine Isotope Stages M2 through KM5.
