Short summary
Marine sediments contain valuable information about past climate changes. However, dating Pleistocene marine sediments can be difficult, and the accuracy of the age model depends on the quality of the stratigraphic alignment target. We introduce three targets – Atlantic, Pacific, and global – with three distinct chronologies for the global target that incorporate astronomical forcing constraints to various degrees. This suite of targets offers flexibility in age model construction.
