CTD Notes or CalCOFI 1611SR:

Standard configuration for Seabird 911+ was used on 27 stations: dual T,S,O2 
pumped sensor arrays; one Wet-Labs ECO-FL fluorometer; one 25cm Wetlabs 440nm 
transmissometer; Benthos altimeter; SBE18 pH sensor; Biospherical surface and 
remote PAR; Seabird remote depth readout box; Satlantic FRANKS-ISUS v3 & battery 
(recently upgraded to firmware v3; repaired, just back from Satlantic); SBE32 
carousel.

On 48 casts, the secondary SBE43 oxygen sensor and altimeter were removed and a 
RINKO III (ARO-CAV model; s#0251) was installed. The RINKO III sensor requires 
two channels for oxygen current and temperature. The Altimeter and Second SBE43 
O2 sensors were removed on these stations since the altimeter was not needed. 
The RINKO III acted as the secondary oxygen sensor.

All casts were performed on RV Sally Ride's SBE11 deck unit & Windows 7 64-bit 
PC using com settings set by RV Sally Ride IT tech. SIO-CalCOFI's new, white 
epoxy-coated, metals-free LARS rosette with 24-10L PVC no-metal, productivity clean 
bottles with silicone o-rings.

RV Sally Ride has 0.350 single-core conductive wire; STS performed the 
termination and it worked for all casts. The new SIO rosette has a LARS bracket 
to interface with the RV Sally Ride forward CTD winch system. It worked 
flawlessly and allowed us to deploy without taglines on deployment or recovery. 
It worked especially well during rough weather on stations which most likely 
would have been cancelled on any other ship.

CalCOFI 1611SR CTD O2 Sensor Configuration Notes: A RINKO III oxygen optode 
sensor was deployed on stations that did not require an altimeter. The 
RINKO requires both voltage channels and we do not have two free when needing 
the altimeter. So after cast 003, the secondary oxygen and altimeter were moved 
to to their own cable (Universal Y) for use on V4 & V5. The RINKO was connected 
to its own cable and the cable on V4 & V5 were swapped when the altimeter was 
not needed.

There are 48 casts with the primary O2, RINKO, and no altimeter. The calculations 
of RINKO oxygens are completed and are integrated into the CTD.csv data as secondary
oxygens.

There are 27 casts with two SBE43 oxygen sensors and one altimeter. Please note
that secondary SBE43 oxygen and RINKO III oxygen data are combined in the database
csv.

samples taken Cast 006: 93.35 - DIC station; no console ops comments Cast 007: 
93.40 - "No signal seem from RINKO O2 sensor" comment but okay since RINKO O2 
data were not displayed and secondary O2 sensor was offline. Long slow rollers; 
transmissometer dropped out at ~440m on downcast. Cast 008: 93.45 - Prodo, 
really late; pH 12473 taken; Bottle #8 replaced pre-cast, bottom seal poor, 
leaky; bottom valve #14 replaced pre-cast, drippy. Transmissometer drop out at 
~494m on downcast. Cast 009: 93.50 - no con ops comments Cast 010: 93.55 - no 
con ops comments Cast 011: 93.60 - no con ops comments Cast 012: 93.70 - early 
prodo cast; grey morning, some wind chop; bottle #23 (extra 10m NCOG) top lid 
was open upon retreival. In the mixed layer so probably fine, bottom closed. 
Transmissometer looked good the whole cast. Cast 013: 93.80 - EK80 was not 
logging data, told Dan. Cast 13 = Nov 8th Election Day (Trump vs Hillary) Cast 
014: 93.90 - no comments; pH sample 12474 taken Cast 015: 93.100 - bottle #22 
tripped on deck Cast 016: 93.110 - cast restarted since data acquisition was not 
started (0638 vs 0616 start time). Yo-yo dur to "not archiving",. "Haste makes 
waste" comment. Drifter bottle (box 1/3) tossing every 15mins started after 
leaving station. Cast 017: 93.120 - prodo cancelled - too late; changed bottom 
valve on #11 pre-cast, too hard to open & close even when "backed off". Drifter 
bottle box 2/3 deployed, one every 20mins on transit to 90.120 Cast 018: 90.120 
- chl max = btl 14/NCOG station; 0 & 30m DIC-pH samples taken plus underway pH 
sample 12475; Drifter bottle box 3/3 deployed, one every 20mins during transit

UTC" DMW comment on console ops. PST was 0048-0140 Cast 020: 90.100 - prodo, 
nets done first, cast started 1.1km from sta start; some long rolls; bottle #18 
mistripped, fired but no closure = no samples, prodo samples taken from #19 
(mixed layer so acceptable) Cast 021: 90.90 - 3500m deep station, DIC+NCOG sta, 
underway pH 12478 taken; pH, PAR, ISUS & battery taken off, connectors dummied. 
Transmissometer dropped at ~610m on downcast. V3 = PAR, V6 = pH, V7 = ISUS Cast

taken Cast 023: 90.70 - NCOG station; no con ops comments Cast 024: 90.60 -
prodo & DIC sta; broad chl max. Transmissometer out @~280m downcast Cast 025: 
90.53 - DIC+NCOG sta; no con ops comments; on track to make Naval Clearance 
window for sta 90.45 Cast 026: 90.45 - 0 & 30m DIC-pH sta; originally misnamed 
1611024 - all files renamed to 1611026 after <ctrl><alt>B backup didn't work. 
CTD cast time 2121, inside the naval clearance window Cast 027: 90.37 - 0 & 30m 
DIC-pH sta; no con ops comments Cast 028: 90.35 - no altimeter on 360m station 
so CTD sent to 350 (next sta is deep so altimeter will be installed before sta 
30) Cast 029: 90.30 - prodo & DIC sta; Cast 030: 90.28 - 0 & 30m DIC-pH sta, 
underway pH 12528 taken; shallow station, altimeter & secondary SBE43 O2 sensor 
reconnected, RINKO disconnected and dummied for coastal run. O22 on V4, 
altimeter on V5. Universal Y on V0/V1 changed in hopes of eliminating 
Transmissometer dropouts Cast 031: 90 27.7 SCCOOS - Dana Point afternoon station 
(1514PST) Cast 032: 88.5 30.1 SCCOOS; no con ops comments Cast 033: 86.8 32.5 
SCCOOS; no con ops comments Cast 034: 87.33 - 0 & 30m DIC-pH, plus underway pH 
12531 taken; Cast 035: 87.35 - DIC sta; DMW used rinko.xmlcon file but dual 
SBE43 O2 sensors still online. CTD data processed using correct xmlcon, not 
rinko.xmlcon Cast 036: 87.40 - SM Basin but normal cast to 515m done; 
rinko.xmlcon used but dual SBE43 sensors still online. CTD data processed using 
correct xmlcon, not rinko.xmlcon Cast 037: 87.45 - nets first prodo sta; CTD 
cast started ~1.1nm from sta coordinates (acceptable with dynamic position 
stopping drift); Remote PAR shaded by ship then clear ~30m; transmissometer 
working well now after Y-cable change Cast 038: 87.50 - San Nicolas Island 
station, shallow; altimeter & dual SBE43 O2s still installed Cast 039: 87.55 -
RINKO III O2 sensor installed pre-cast; no con ops comments Cast 040: 87.60 - no 
con ops comments Cast 041: 87.70 - xtra bottle @45m for LTER chl max; 3 xtra @ 
10m for LTER Size Fractionation and NCOG experiment Cast 042: 87.80 - prodo sta; 
moderate seas, ~15min "no serial data" winch delay (winch readout failure) Cast 
043: 87.90 - interesting T, S, O2 "feature" ~90m on downcast; underway system pH 
12542 drawn Cast 044: 87.100 - no con ops comments Cast 045: 87.100 - no con ops 
comments Cast 046: 87.110 - prodo sta, grey morning. (Nov 15th birthday) Cast

taken; no con ops comments Cast 049: 83.90 - pH 12543 taken; no con ops comments 
Cast 050: 83.80 - prodo sta; rough seas, no nets (winds 40+kts), no secchi for 
prodo 18m used (from database); big rolls, dampening system not used. Noticable 
different between upcast and downcast between 0-50m. Hove-to while sampling 
post-cast. Langmuir circulation visible in 18khz acoustics Cast 051: 83.60 -
still rough, no nets; CTD "yo-yo'd" between 338 & 438 on upcast, wrong depth 
given to winch, went back to 438 Cast 052: 83.55 - still rough, no nets; CTD-
only; RINKO sensor disconnected (a station early), dual SBE43 O2 sensors back 
online, with altimeter (alt.xmlcon) Cast 053: 83.51 - still rough but only Manta 
net tow cancelled, all other nets done; original station schedule had us head 
north after this station but with the lousy weather, we headed shoreward. 
Weather will improve in ~24-36hrs. Cast 054: 85.4 35.8 SCCOOS - calmer inshore; 
southward SCCOOS done now so prodo will be at 83.42 Cast 055: 83.42 - 95m prodo 
+ 0 & 30m DIC-pH sta; calm, warm morning; top hose clamp on bottle #8 broke -
replaced Cast 056: 83.3 39.4 SCCOOS - leapfrogged over 83.3 40.6 because a 
fishing boat with net in the water was on our station position. So we headed 
shoreward and will come back. "No serial data" winch scoreboard problem. Cast 
057: 83 40.6 - 0 & 30m DIC-pH sta; fishing boat clear of station, but no winch 
operator for ~10mins - Henry launched while CJ was called (on the phone, 
personal call) Cast 058: 81.7 43.5 SCCOOS - no con ops comments Cast 059: 81.8 
46.9 (82.47) Santa Barbara Basin DIC+NCOG station. CTD terminal depth 10m off 
bottom. Cast 060: 80.0 50.5 SCCOOS - looks like pump may have sucked something 
up @ surface, end of cast Cast 061: 80.51 - DIC sta; no con ops comments Cast 
062: 80.55 - DIC+NCOG sta; no con ops comments Cast 063: 80.60 - DIC sta; early 
prodo station, calm sunny morning, nets first; small blue shark swimming by at 
CTD launch Cast 064: 80.70 - DIC+NCOG sta; calm afternoon; some swell Cast 065: 
80.80 - DIC+NCOG sta; no con ops comments Cast 066: 80.90 - DIC+NCOG sta; 
underway pH taken #12606 Cast 067: 80.100 - prodo & DIC+NCOG sta; weather 
picking up a bit, some rolls Cast 068: 77.100 - unusual salinity & temperature 
profile @65m; pH 12615 taken; Th-234 McLane pumping done for ~45mins @100m (Tom 
Kelly, FSU) Cast 069: 77.90 - no con ops comments Cast 070: 77.80 - no con ops 
comments Cast 071: 77.70 - prodo sta; primary conductivity is wonky - secondary 
conductivity looks fine = biofouling? At depth, primary & secondary agree okay. 
Use upcast data for oxygen and all other measurements but still a bit wonky. Big 
swell, long period not helping. Post-cast note: plumbing back flush w/ fresh 
water hose = pressure; nothing visibly blown out. Cast 072: 77.60 - salinities 
agree and look better this cast; still long period, big swell. Upcast does look 
different than upcast even though dynamic positioning has us on the same 
coordinates = internal wave? Cast 073: 77.55 - DA from bottles 19, 21; altimeter 
and second SBE43 O2 sensor installed, RINKO disconnected (alt.xmlcon) Cast 074: 
77.51 - no con ops comments Cast 075: 77.49 - no con ops comments Two nets-only 
stations occupied after 77.49 - sta 83.60 & 83.55, Bongo, Manta, Pairovets net 
tows missed during rough weather were done. CTD profiles not requested by NOAA 
Fisheries. Th-234 45min filtering done at 83.55, 100m - last operation before 
heading home. Weather at 83.60 & 83.55 was moderate, not calm, with winds ~20-
25kts
