"_ Depths are weighted according to the mass of benthic forams use from adjacent cm slices for dating, and corrected according to Skinner and McCave (2003)"																
"_ Planktonic dates have been interpolated where directly paired dates do not exist, undertainties are indicative from the nearest planktonic date."
