Sedimentation rate of sediment core PS1507-3

estimates based on radioisotope stratigraphy calculated in two different ways, first by assuming that the maxima in the radionuclide profile at 37.5 cm represent the maximum productivity in isotope stage 5e (120ka), and second that the respective minima at 57.5 cm mark the boundary between isotope stage 6 and 5e (130ka)
