Depart: 06:00 - 15:30

Attempted recovery of M2H (46044).  Winds were sustained 20 knots for 48 hours.  Seas 6-8', 10 s.  
Wind backed down to 15 knots allowing a window for recovery.  The EdgeTech acoustic release failed 
to operate and continued to indicate a non-release after the release code was sent.  All permutations of 
sensitivity, transducer depth, distance from mooring were tried.  Codes were verified against 3 documents 
and ultimately the company.  Possible reasons are excessive engine noise from vessel (12 khz interference) 
or low battery.  Towing the buoy was tried in case the unit had released but was mechanically stuck. 
The towing line parted during a large surge.  Further attempts to release were made and finally the release 
was disabled.

M2H (46044) recovery 03May2015 @ ~09:00 PDT

M2H (46044) was recovered by the USCG buoy tender Aspen after it broke free of its mooring 
on the morning of 02May2015.  Reports indicate that the top splice of the 220m Fishbite line failed 
leaving only the thimble at the end of the Nilspin cable.  The buoy made steady progress northward
at 0.2 - 0.5 knots.  NDBC notified the USCG and they tasked CG Aspen with the recovery.  All instruments were recovered, but the
mooring line from the anchor to the Nilspin remains onsite.  MBARI instruments including CT sensors 
from NDBC will be recovered from Yerba Buena Island USCG facility on 18May2015.  Data will be
recovered by MBARI and NDBC sensors will be shipped back.
