MON 22-OCT-2007 (295) - E-MAIL FROM MARK ------------------------------------------------------------------- Date: Mon, 22 Oct 2007 11:39:42 -1000 From: "Mark Yarbrough" Subject: MOBY dive "cal" trip Hi All, I had one day available to perform the MOBY servicing this month. The HRA boat was only available for the 20th of October. This was the first predictable good weather we have had since the first week in October. The trip one week earlier had to be cancelled due to changing weather. We isited the MOBY site to photograph and clean the MOBY optics. I also wanted to download as many MOBY data files for "good" days as time allowed and check on the Argos transponder. There was a big fouling problem with the upper arm Lu collector. There was a barnacle growing inside the anti-foulant tube directly on the copper tube. This is the first time we have seen this happen. There was also another small barnacle deeper in the tube. Only the largest one was big enough to cause interference with the optical path. It appears there were two small drops of something on the inside surface of the tube that allowed the barnacles to attach. The biggest barnacle was about 0.75" long, the other about 0.125" long. This amount of growth occurred over the 5 week period since deployment. I can only guess that this tube was contaminated with something during handling or while sitting exposed by the sink or on the deck of the ship. I will keep the tubes sealed an much as possible on deck, in case this was the cause. I will also instruct the divers not to hold the tubes with fingers in the hole. No other problems were noted. The good data files were recovered and transferred to MLML. The Argos unit was turned on and is working again. The bird "pokers" seem to be keeping the birds off the top of the Mooring buoy as the solar panels are staying clean, so far. Mark Yarbrough, Ch.

WED 21-NOV-2007 (325) - E-MAIL FROM TERRY ------------------------------------------------------------------- Subject: November trip to Maui From: Terrence Houlihan Date: Wed, 21 Nov 2007 09:41:26 -1000 Hey guys, I got back from Maui Tuesday afternoon. Guy Hagi lied when he predicted light and variable winds for the beginning of the week. They werent. We didnt get any calibrations done but I did get all the files downloaded for potentially good days. When we arrived at the buoy on Monday we saw that the tether was wrapped so we fixed that and Steve took some pictures. Steve also saw some fouling on the top Lu. He tried to document this and the chaffing but the photos turned out a bit on the darkside. I downloaded data and we had about a 2.5 hour boat ride home. The winds actually dropped over the course of the day so it looked promising for Tuesday. Not to be. Tuesday was actually worse. We got the cleaning done, the antifoulant tubes installed, the new white cable installed and spent the rest of the day rolling around in the aluminum boat and downloading data. The data has been transferred to the webspace under my subdirectory, M239. There is also some new weather data on the website (Steph). Terry
WED 28-NOV-2007 (332) - E-MAIL FROM MARK ------------------------------------------------------------------- Subject: Re: November trip to Maui From: "Mark Yarbrough" Date: Wed, 28 Nov 2007 11:19:37 -1000 To: "Stephanie Flora" Hi Steph, I think the variability in LuMOS is due to the fact that the flopper stopper bridle was installed in the wrong side of the buoy, placing it in the FOV of MOS Lu as we have seen in the past. This cant easily be fixed after the floppers are deployed. Mark
MON 17-DEC-2007 (351) - On Monday 17 Dec MOBY broke free of its mooring and headed toward Japan. High winds have pushed it 23 nm to the west. The first ARGOS position showing it outside the watch circle was on julday 351 at 12:00 GMT.
TUE 18-DEC-2007 (352) - E-MAIL FROM MARK ------------------------------------------------------------------- Subject: MOBY recovery From: "Mark Yarbrough" Date: Tue, 18 Dec 2007 10:54:10 -1000 Hi All, MOBY has slowed a bit and is almost stationary. Water depth is 600+ meters so there is no chance it is anchored yet. There has been a little movement to the north, so it may oscillate around and take another swipe at Penguin Banks. We can only assume the ARGOS is still attached to MOBY. The drift speed was very fast for MOBY but without other evidence that is all we can assume. So, we will be taking the K/W out to do the recovery. This will be an overnight trip because of the slow return tow speed limit of 2 knots. This is the plan unless something happens to make us leave earlier (Like MOBY drifting too close to shore). We will leave Thursday morning @ 08:00 (winds are forecast to decrease Thursday afternoon). *40+ mile transit to the buoy. (though it should drift closer by Thursday). *Take MOBY under tow as usual. *Tow at 2 knots back to Honolulu and find a lee *SHOULD arrive back in Honolulu harbor area by Friday morning *Lift the lower rack to the surface with lift bags and orange bumpers *Slow tow into the harbor with the lower unit near the surface so we dont touch bottom at the dock. *Recover MOBY with the shore cranes Crew: (7) 2 Marine center personnel (Skipper and 1 crew) Mark Yarbrough Drew Yarbrough Darryl Peters Terry Houlihan Michael Feinholz Mark
FRI 21-DEC-2007 (355) - Draft MOBY Recovery Cruise report (20 to 21 December 2007) R.V Klaus Wyrtki Participants: Tom ?- Captain Mike Hodge - Mate Mark Yarbrough - Ch. Sci. Terry Houlihan - Dive Master, Research Technician Darryl Peters - Diver, Research Technician Michael Feinholz - Research Associate Drew Yarbrough - Student Assistant We departed Snug at 08:00 on 20 Dec 2007. Wind observations at the time were 20 - 25 knot winds, 10-12 ft combined seas with diminishing winds in the forecast, lasting through Saturday. We followed a course directly to the last known Argos position for MOBY. The channel crossing was a bit rough but things calmed down considerably about half way to the MOBY area with only the rather large 8-10 foot swell remaining. We arriving in the vicinity of the Buoy at a bout 2 pm. We posted lookouts - Mike H. in the crows nest, Darryl and Drew on the bow, the rest of us scanning the horizon from deck. We maintained the visual search while continuing on the projected course of MOBY based on the previous hours of position information. We had no luck finding MOBY after continuing on this course for 3 miles past the last known position. By this time Stephanie had obtained a "new" Argos position which was only 40 minutes old - our best yet. We returned to this area and again searched in vain. At this point it was after 15:00, we were stuck as far as chasing Argos positions because we would not likely get more positions for about 4 - 5 hours and we were already losing daylight. We decided to start a spiral search pattern from this last position with a bias to the Eastern direction. We expanded the track by 1/2 mile each circle, reasoning that this pattern would give us the greatest coverage before nightfall and extend well past the possible range of MOBY drift. Most of the problems in sighting the buoy were due to the 10 foot, long period swell which would only occasionally lift MOBY high enough to be within our sight line. On our third circle we sighted MOBY using the stabilized binoculars (we would not have found MOBY in these conditions without these binoculars). MOBY was about 2 miles further east than our estimated position based on the last Argos position and was moving faster than predicted. Observers using the naked eye could see MOBY only when it was less than 1/2 miles distant. Upon inspection, MOBY was found to have a parted and frayed tether and a broken lower arm, otherwise the Buoy was in sound shape. Divers dropped the "flopper stopper" drogue (it could not be recovered with the deck equipment available on the K/W). The tow line was attached to the cut end of the MOBY tether and the broken lower arm was lashed in place on MOBY for the trip back to Snug. Seas were favorable and we were able to tow MOBY at about 3.5 knots (maybe faster when I was asleep). Winds had decreased as forecast so the channel crossing was not bad at all. Crew were able to get a fitfull nights sleep on deck and in the cabin. We arrive in the vicinity of Honolulu harbor and "calm" water at about 08:00 on the 21st. Our goal was to lift the lower MOBY Instrument Bay to the surface and tow MOBY into the harbor in a horizontal position. Divers started by placing lift bags on the lower bay lifting bails. We could only obtain four 100 lb lift bags and these were not enough to lift MOBY horizontal. We knew this was going to be the case and our plan was to use fender floats to do the rest of the lifting. To make this plan work we would need to cut holes in the bottoms of the rubber floats to allow divers to insert the regulator filler. Deciding this was not a great option, we decided to try and use the K/Ws anchor capstan to lift MOBY to the surface and then clip the fender floats while the lifting/tow line held MOBY in place. This worked well and the divers were able to connect as many floatation balls as we had prepared. Terry was then able to remove the broken lower arm from MOBY while the buoy floated horizontally at the surface. We were preparing more floats to add to MOBY but since the buoy seemed to ride well we made the decision to make our way into harbor. Unfortunately after we were committed to entering the harbor - the floatation started to fail. I dont exactly know why but the towing may have helped pull the floats under the surface at which point they start to compress and loose buoyancy (more floats would have helped). Though the MOBY was not riding completely horizontal it was towing at a shallow enough angle (~20 ft deep) to stay off the bottom of the harbor channel @45 ft. We continued the transit without mishap, except for the Matson liner that decided to leave right as we entered. The K/W dropped MOBY at the end of the U.H. Pier. The bottom of MOBY settled into the mud bottom at about 35 ft water depth at the pier. UH personnel used two of the dock cranes to lift MOBY onto the dock and support cradles. The operation was complete by Noon. The rest of the day was spent cleaning up the boat and MOBY. Mark
