General Note on 1207OS CTD Casts & Processing; 2017 reprocessing notes added

1). Sailing on RV Ocean Starr. Wanting to test the CTD winch and wire, the first
station was 93.3 30.0. Prior to the first cast, a weight was put on both winches
to pay out enough to rewrap the drums and test hydraulics. Everything appeared
fine so a full 515m CTD cast was performed.

2). On cast 2, a strand of the CTD wire broke at 515m, more broke as the CTD was
raised so the bottle closures were aborted. Only the 515m terminal bottle was 
closed. July 3rd 2012

3). Since the CTD conductive wire was bad, the ship returned to San Diego and
the cruise was postponed till new wire could be shipped & installed. 
The Cruise resumes after 7 days, on July 10th 2012.

4). Cast 5, SCCOOS sta 91.7 26.4 5m bottle did not close. The CTD was sent back
to 5m after the surface bottle was closed and another 5m bottle was closed. 
Bottle #1 broke during recovery.

5). Cast 11 - ISUS dropout at 150m to 315m during the downcast.

5a). Cast 18 - 382m bottle salt looks bad, removed

6). Cast 21 - shallow chlorophyll max; ISUS dropout 214-276m downcast.

6a). Cast 25 - ISUS dropout at 214-270m downcast

7). Cast 32 - ISUS battery not working - data coded "9". Changed after cast.

8). Cast 37 - ~800m Santa Monica Basin Station, altimeter flakey so rosette may have
touched bottom. Secondary O2 sensor data on upcast looks bad - will be replaced.
Upcast secondary conductivity-salinity sensor data also look questionable; both
secondary salinity and secondary oxygen data coded "8" on upcast. Primary sensor
data look fine.

9). Cast 38 - new SBE43 O2 sensor installed on secondary O2 channel pre-cast.

10). Cast 39 - 40m bottle did not close, sent back down to 40m to get water 
after surface bottle was closed.

11). Cast 45 - extra LTER 10m bottle forgotten, CTD went back down after surface
closure for the extra 10m bottle.

12). Cast 50 - rough weather begins...through cast 53

13). Cast 62 - upcast data may be compromised by jellyfish being sucked into the
pump on the upcast. Data between 470-380m on upcast looks fishy.

14). Rough weather again Cast 64-69..

15). Cast 66 - extra bottle fired at 240m by mistake, skipped. 87m bottle missed
so CTD-rosette was lower back down after missing that depth.

16). Cast 69 - ISUS voltage dropout 371-438m downcast.

17). Cast 72 - extremely calm sea conditions. ISUS voltage dropout 243-322m 
downcast. Salinity & oxygen upcast data look bad from 33-0m, biofouling suspected.
Small fuel leak delayed secchi after Bongo net tow.

18). Cast 73 - ISUS dropout 251-320m downcast.
