Figure F9. Conventions used to measure dip and dip direction of structural features during Expedition 330. A, B. Core face coordinates. The turnable (hinged) plane of the goniometer was rotated until parallel with the feature to be measured on the archive half. Data were recorded as dip angle and dip direction relative to archive-half core face coordinates. Values were then rotated to (C) core reference frame, with pseudonorth pointing out of the archive half. Dashed lines indicate obscured half of core. Modified from Shipboard Scientific Party (1997). MMT = M. Meschede tool (designed during ODP Leg 170).
