Figure F37. Plot of results of the end of Deployment 2, Site U1402. At 2040 s, the pumps were turned on to establish circulation. A minor increase in the standpipe pressure indicated circulation was unimpeded. At 2130 s, the pumps were turned off and were turned on again at ~2150 s. This time the standpipe pressure rose dramatically. In addition, the accelerometer recording acceleration in the vertical direction recorded a significant displacement (H). At this point the tether failed.
