(Table 1) Occurence and age of sapropels from different ODP Leg 107 holes

Sediment depth is given in mbsf. Ages from Leg 107-650A were interpolated between Base NN21 (0.26 Ma) al 147.9 mbsl, Brunhas/Matuyarna boundary (0.73 Ma) at 415 mbsl and top Olduvai (11.67 Ma) at 580 mbsf. Ages from Leg 107-651A were interpolated between Brunhes/Matuyama boundary (0.73 Ma) at 309.4 mbsf and top of Olduvai (1.67 Ma) at 341.7 mbsf. Biostratigraphie Datums from Leg 107-653A were used to calculate Ages in Hole 653B.
