Abstract | The EXCO area, a region of "normal" Pacific crust formed at the East Pacific Rise spreading centre around 13°S and well away from extensive influence of major fracture zones or spreading centre jumps, was studied during SO145. The main objective was to sample the pore waters and Layer 2 rocks in an effort to establish the chemical changes which are occurring in this aging crust. During SO145 about 4400 km of Hydrosweep data were collected representing an approximate seafloor coverage of 29000 km2. For consistency with the SO105-cruise the SVP model given by Weigel et al. [1996a] was used; a comparison between CTD measurements of SO105 and S0145 cruises provided reasonably the same velocity-depth models.
