PnB Cruise Notes

pb221 -Switched to Wetlabs DH-4

pb252 -no files recorded on DH4 for stn7 and stn4D

pb253 -double cast on station D. Cast #2 is good. -Cast E on PRR is bad. Roll column is not correct.

pb255 -termination failure due to water ingress. Short and blown fuse. Decided to use alternative termination methods.

pb258 -2-amp fuse issue with CERB sys. 23 stn 4. no data collected. Fuse later replaced with correct 5A

<====================================================================>

02/??/2009 Bad HS-6 cal

09/??/2009 bad AC-9 cal

10/??/2012 AC-9 0187 Factory Service

09/24/2013 New DH4 lithium batteries.

01/10/2014 Noticing problems with LISST data jumping on pb253, beam C has been off since pb24#

02/6/2014 Noticed PRR 510 channel is off, and has been since pb250/pb251

02/7/2014 LISST 1284 depth offset reset +3.69m set to 0.0m in air.

03/2014 LISST 1284 LREF value does not match transmission.--Tau and Beam-C are off due to this. Sent into service.

04/22/2014 Alpha-Q may be producing high bubbles causing issues with ZSCAT and other Qwater standards.

09/09/2014 No Q-water zscat was performed for pb261. Used pb260. #1284 was swapped back on rosette after pb260. pb262 zscat done 9-9-2014

09/17/2014 Something strange with pb261 LISST files. Two short files and no defined "A" cast.

09/25/2014 pb263 suspected termination failure on stn 3. 120m profile. High winds. No PRR. Test uPro

10/21/2014 pb264 Y cable to temp and cond. sensor damaged, replaced with IOP frame spare. New Electrical termination on CTD.

11/26/2014 pb265 AC9 depth values seem suspect, LISST1284 depth off by 3.35m

12/18/2014 pb266 No AC9 data from stn 4 to stn 1. Suspect cable issue.

12/18/2014 pb266 LISST 1284 is -4m off. Needs reset.

01/05/2015 pb263++ File format for C-OPS on PnB needs to be consistent: PB#_STN#_Date_time_cast#.tsv

03/20/2015 CTD Y-cable Temp Sal (not on this date-still need replacement)

03/26/2015 PB267 Battery left on, no AC9 data for stn 4, 3, 2, 1

03/26/2015 PB267 No CERBERUS data recorded for stations 7 and 6

04/16/2015 PB268 Choppy conditions, no AC-9 3, 2, 1. Suspect DH4 battery failing.

08/26/2015 PB271 Wire Jumped shiv and pinched. No CTD casts. Cable was rusty. C-OPS#41 tested

09/01/2015 AC9 0159 swapped in place of 0184. 0184 went to Wetlabs for service.

09/24/2015 PB272 Observed temperature dependence of Transmisometer. Values are unreliable. C-OPS software version crashing 1.8.5

10/15/2015 PB273 Transmisometer swapped with backup, backup also shows same problems, Brandon Russell Spectroradiometer JPL

11/19/2015 PB274 Transmisometer seems to work now. Bottle firing issue with CTD, two casts on station 4, second is full cast. C-OPS 1.9.2 software crashed a lot. No logical LISST files. Date is incorrect in LISST sensor. No C-OPS for station 6.

12/14/2015 Electrical Re-termination. Termination docs

12/17/2015 Control box issue, only manual bottle fire control. More problems with C-OPS software. Reverted to very old version.

01/28/2016 AC9 0187 returned with many parts replaced: filter wheel, a tube, new a detector, new bearing, windows

02/12/2016 AC9 0187 installed on rosette, transmissometer 146PR installed.

4/27/2016 PB277 Bad weather conditions, only a couple stations sampled

05/19/2016 PB278 CTD Electrical termination failed on station 5. C-OPS 23 used.

06/23/2016 PB279 C-OPS deck unit not working. Possibly broken during NAAMES cruise.
