Deployment Events
(2156) - When Plotting TT7 Mains (volts) time series for the intcal it is noted that the values
were below 11 volts ALOT ~50% (see dir Dennis_Clark_docs\081008_intcal_plots
plot_intcallam1P_vs_time(44,1,22,0).
Also the System current and coolant flow was anomalous.
And the blue and red array temps got upto 20 deg C!

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.

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).

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.

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.

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)

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.
