Precise mapping of composite section to logging equivalent depth at Site 1265. 41 tie-points have been picked in between 71.45 mbsf and 292 mbsf logging depth, and constitute the basis for locally adjusted compression ratio. Above (pipe) and below (poor core recovery) this interval, no correlation is possible by lack of data, and a linear extrapolation was used. As a result, the mean compression ratio (~15%) is in very good agreement with the core-derived composite depth growth rate. Lower part of log subunit 1a and log subunit 1b (mean density 1,9 g/cm3 almost constant within this interval) is characterized by a lower expansion rate.
