Figure F5. A. Installation of the reentry cone and steel casing in Hole 1224D as observed on deep-source records. This figure is excerpted from the EPC graphic recording on 2 January 2002. The traveltime interval shown is ~410 ms; the light horizontal traces are spaced at 100 ms. The heavier vertical traces are 5-min marks. The fluctuation of up to 4 ms in the traveltime of the direct water wave is primarily due to the heave of the ship pulling and slackening the vibration isolated television (VIT) frame cable. The 1- to 2-ms fluctuations in the traveltime for the reentry cone is a measure of the VIT heave plus the uncompensated heave of the drill string because the cone is rigidly linked to the ship's heave compensator by the drill string.
