From Thompson: Cha-ba is repaired, NEMO-Subsurface is redeployed and working perfectly!  We’re on our way home now.  Here’s the update email I just sent:

All,

We're happy to report that Cha Ba is back in the water, successfully deployed at 2100 last night.  The system has a redesigned power and battery system that should give it 4x longer endurance than before.  We worked hard for 4 days to completely redo this complicated system - and even added a wind power generator!  

Best of all, we didn't waste a second of ship time since the three volunteers aboard helped us collect a beautiful time series of T, S and velocity in Juan de Fuca canyon while we did so.  We also managed to fill in some gaps in multibeam bathymetry for both Will Wilcock and the Olympic Coast Sanctuary folks.

The subsurface mooring component of this mooring system, which we call NEMO-subsurface, was also successfully deployed today and is working as planned, with data being telemetered back to shore using Cha-Ba as a relay to reach the coast guard antenna in La Push - and back to APL from there.  This state-of-the-art system is delivering hourly profiles from 19-m to the bottom of T, S, O2, chlorophyll, vector velocity, and nitrate.  We're really excited about these time series of continuous profiles.  We may need to work with Emilio to get the subsurface data onto NVS; I can't recall where we were with that.

Unfortunately, the deeper inductive sensors are not functioning right now on Cha-ba - however this is much less of a blow since we will turn the full system around in October and they are nearly completely redundant now that the subsurface system is fully operational.

Thanks to all - this was a huge effort made possible by the availability of Thompson days at the end of Jim Mercer's cruise, and his willingness to let us use them - so a big thanks to Jim.  Also, we owe thanks for the hard work and great engineering of Chris Siani, Mike Kenney and Paul Aguilar, and for their availability for a 5-day cruise on short notice.  Same for Colin Smith, who was a huge help, so thanks to him and to Al for making his time available.  The captain and crew of the Thompson were, as always, great.  Last but not least, Shuang Zhang, a graduate student working with Jan and me, and the volunteers for standing CTD watches for 36 continuous hours.

From Revelle: All moorings are recovered!  The gang there is now downloading data and resting after a harrowing few days.  Great job to all!!!
