Today:

- Sonics 672 and 1123 were FedEx'd from Boulder to Campbell, after determining (through swapping head/electronics) that 1123's head was bad (and we knew that 672's head was loose).  Ed thought it was possible that these could be returned by mid next week.

- Chris and Lisa removed sonics from the 8m and 30m levels at MFO (sorry, Ned) and brought them back to Boulder.  Kurt will take them to SCP tomorrow to (finally) install A6 and replace A17.  We'll look at the data to see if sending A17 back to Campbell is justified.

- While at MFO, Chris and Lisa also replaced a PTB220 barometer with the MPL solid-state barometer.  Kurt also will take the PTB220 to SCP tomorrow to install at A3.  I verified that data were coming in from the MPL.  Note that I deleted the reference to a qc_file P.dat in manitou.xml (only on this DSM) since the default $QC didn't point to it and thus produced NANs.
