May 31--Gordon recovered from Tasman Bay. Waiting for Chris P arrival and uncanning.June 1 -- Uncanned Gordon. Sub1 valve makes weak flubbing sound, not nice strong click. No sub getting to the arrays; this explains their darkness. June 24 -- Sea van leaves NZ. Scheduled to arrive Oakland July 15. WHOI Deployment of ESP-ChrisApril 15 -- Roman flies to WHOI; returns May 5 May 2 -- Deploy ESP-Chris June 4 -- Discover intake syringe mechanism has failed; jams under load but works fine when moving air.

California Deployment of ESP-Gordon / NEOAug 30 -- Haul instrument and gear in trailer and MBARI van to deploy on OCSD R/V Nerissa. Calm seas, hot weather, instrument in ~10:30am. Gordon w/PCR, CTD, ISUS, cell-phone modem (T-Mobile). Sewage diversion to begin Sep 11, 2012. Machine located at 33.59703 -117.94623. Divers from Orange County Sheriff's dept. Kevan collecting data here: http://www.stanford.edu/~kevany/ESP/. Sep 14-noticed CTD battery draining faster than expected because of optode. Also, ATV encoder in MFB kept returning 511, which is 2**9-1 meaning all bits are stuck high--typical way they fail. Stopped PCR, continued SHA, but with dead CTD no contextual data to adaptive sample off of. Decision to flip for NEO on Sep 26. Sep 26-recovered ESP-Gordon and swapped both batteries and ESP-Neo. Also changed CTD so now no optode (O2) measurments. One power cable fizzed away. Connector on pickle jar loose. But NEO now running well. Skipper gave deployment coordinates of 33 35.829 -117 56.759. Xeos says 33.59702 -117.94604. Water depth 18m. CTD/can depth=6.3m. Divers from LBAoP--Eric Castillo and Steve Lang. Oct 16-Recovered ESP-Neo. Divers from LBAoP--Steve Lang and Veronica Anderson. Fall CANON--Drifter with ESP-Moe / MoeWF leaves MBARI Sept 10. Moe with PCR, ISUS, CTD, PAR, and buoy has downward ADCP. Roman and Julie R. on ship. Moe went into water Sep 11. First phase slated for 6pm. Pulled Sep 17 (10:30am). E/M cable started flaking out either due to connector or bad ethernet extender. Decision to end mission unrelated to this. |
