Notes: To synchronize the new velocity data to other logging data of the Borehole Research Group at Lamont-Doherty Earth Observatory (LDEO-BRG), we used 14 prominent features of the IMPH resistivity log. The synchronization was achieved with the linear mode of AnalySeries 1.2 (Paillard et al., 1996). We consider the large depth shifts within the interval 207-212 mbsf as unrealistically high. Therefore, the correlation within this interval might be wrong.
