Finally with the calibrated age we created an age model for one of the cores (HOLCAR03).
The deepest sample we dated was more than 40 ka (thousand) years old. As the core is almost 2 m long, we will have to use a different method to date the lowest part of it. Probably we'll use the oxygen isotopic composition of multiple samples of planktic foraminifera to create a curve that can be correlated with other paleorecords that have been dated using the U/Th series in coral samples. This way we'll be able to assigned dates to those sediments older than 60 ka.
