Sonic temperature bugs: general slow response problem leading to errors of +/- 6 degrees from ambient, and an additional nonlinear error in the slow response when the ambient temperature is between -5 and 5 degrees. The fast response (> 1 Hz) of these sensors is still accurate. Therefore, flux measurements using the detrended temperature data should still be valid. w bug: positive vertical velocities w output by the anemometer need to be multiplied by 1.166; negative vertical velocities need to be multiplied by 1.289.

- CE02SHSM deployed Oct 10. The Power System Controller (PSC) failed 9 hours later.

- CE02SHSM recovered Oct 14.
Buoy from CE02SHSM swapped with recently recovered CE04OSSM. CE02SHSM's refurbished instrument plate was moved to the recently recovered CE04OSSM buoy, so the hybrid buoy to be deployed had a newly refurbished METBK-CT and PCO2A. Other METBK sensors from previously deployed CE04OSSM remained, but they were all still working and their calibrations would still be valid through the end of this fall deployment. The electronics inside the recently recovered CE04OSSM buoy were still working when recovered, so we expected them to continue operating.
The recently recovered CE04OSSM buoy didn't have an FDCHP port, so that instrument could not be moved over from the failed CE02SHSM buoy.

- Oct 15 CE02SHSM with the buoy from CE04OSSM was redeployed

- The PSC failure was characterized after the cruise and discussed with the team at WHOI that refurbishes PSCs. Similar problems will be avoided in the future.
