Downcore data for core M77/2 52-2. PD is the mean pore density of Bolivina spissa for this depth. N is the number of specimens used for the pore density analysis in this sample. [NO3-]BW was calculated from the pore density of Bolivina spissa using eq. 3. δ18O and δ13C were measured on Uvigerina peregrina. δ15N was measured on bulk sediment.
