Summary of Dive R484: For about the first half hour of the dive the log entry program was shut down. During the collection of the first suction sample it was rebooted. | |||||||
Mkr-33: SS of mat; one nearly whole crab captured, TLC recovered, deployed bactraps. Cloud: Two bactraps and one MTR recovered, deployed bactraps, short worm survey. | |||||||
Suction sampler clogged on first sample. Color balance on frame grabs was poor. The sub lost hydraulic fluid which forced the end of |
