Resumen:
The aim of this project is to core a key geological section in the Antarctic Peninsula region. The James RossBasin, east of the Antarctic Peninsula, contains the best high-latitude section in the world that spans more than40 million years of geological history from the mid-Cretaceous to the mid-Cenozoic (80-34Ma). More than6500m of marine and estuarine sediments were deposited during the filling of the James Ross back-arc basin.The sedimentary succession is extremely fossiliferous, yielding diverse invertebrate, vertebrate and plant fossilassemblages, allowing detailed reconstructions and integration of both terrestrial and marine systems. The sequencealso contains a key global reference section for the Cretaceous-Palaeocene extinction event at high latitudes.
