Publication: Glacial onset predated Late Ordovician climate cooling

Paleoceanography_2016.png

Keypoints:

  • Earth system model providing the first detailed simulation of Middle to Late Ordovician land ice growth
  • Model/data comparison suggests a Darriwilian age for glacial onset
  • A single ice sheet of large extent covered Gondwana during the Hirnantian glacial maximum.

Publication: High dependence of Ordovician ocean surface circulation on atmospheric CO2 levels

paleo3_2016.png

Highlights

  • We model Early, Middle and Late Ordovician ocean surface circulation.
  • Our basemaps are fully compatible with the most recent palaeontological databases.
  • Synthetic maps are produced to aid the interpretation of palaeobiogeographical data.
  • Major patterns of modelled ocean surface circulation appear to be model-independent.
  • Ordovician surface circulation is highly dependent on atmospheric CO2 levels.
