General notes: Station Pattern & Cruise Track

Leg 1: CalCOFI 0804JD • 24 Mar - 9 Apr 2008 • NOAA RV David Starr Jordan • San Diego to San Diego
Leg 2: DEPM 0804JD  • 11 Apr - 1 May 2008 • NOAA RV David Starr Jordan • San Diego to San Francisco

• Leg I : Departed San Diego on NOAA R/V David Starr Jordan 0800 24 Mar 2008. Returned to San Diego  9 Apr 2008.  Sixty-six standard and 9 SCCOOS stations were scheduled for Leg 1.
• Leg 2 : Departed San Diego on NOAA R/V David Starr Jordan 0800 11 Apr 2008. Returned to San Diego  1 May 2008.  Trawling and CUFES surveying to Pt Conception, picking up CalCOFI stations missed on Leg 1, then CUFES and station work northward to Line 60 (San Francisco).
• Number of participants: Leg 1: 14 scientists, technicians & volunteers; Leg 2: 10 scientists, technicians

CTD data from both Legs are included here since Leg 2 continued to use Leg 1's CTD-rosette. It should be noted that fewer analytical samples were collected on Leg 2 due to the reduction of at-sea analytical personnel. Also there was a significant number of trawl and pairovet net tow stations during the transit N to Line 76.7. Leg 1 finished with station 059 then Leg 2 occupied 88 net tow stations, 060-148, before picking up the CTD casts missed on Leg 1 plus some additional northern stations. Leg 2 CTD casts were numbered 150-177.

Cruise and CTD Data Processing Notes

CalCOFI 0801JD on NOAA RV David Starr Jordan successfully occupied 59 of 75 scheduled stations on Leg 1. Rough Spring weather delayed station work badly so only 59 stations were occupied Leg 1. Leg 2 tried to pick up some of the stations lost on Leg 1 during their transit to Line 73.3. Leg 2 continued the station pattern north of Line 76.7 primarily trawling and CUFESing (fish egg survey), stopping on stations for quick CTD profiling. Please note that the CTD cast numbering of Leg 2 may not be consecutive since "order occupied" numbering increments for any trawl or net tow, regardless of CTD ops. 

CTD Casts on Leg 1: 001 - 059; Leg 2: 150 - 177 (non-consecutive)

Seabird 911+ configuration (#26277):

Primary Temperature (#1324), Conductivity (#042206), and O2 sensor (#430090), pumped (#2236); Secondary Temperature (#1049), Conductivity (#722) pumped (#68); Wetlabs CStar (CST-810DR) 25cm transmissometer (mislabeled Chelsea/Seatech in con); Seapoint chlorophyll fluorometer (SCF2483 @10x); Benthos/Datasonics Altimeter (#7601); MBARI-ISUS v2 (#111); remote PAR (#4544), no surface PAR was installed. (Freq0=T0; Freq1=C0; Freq2=Pr; Freq3=T1; Freq4=C1; V0=Trans; V1=Fl; V2=ISUS; V3=open; V4=O21; V5=open; V6=Alt; V7-PAR)

Note: continual problems with consistently powering the ISUS resulted in a new protocol after these early cruises where we swapped batteries every third cast. If the ISUS was not unplugged post-cast right away, the battery would not last 3 casts. Starting in 2009, the ISUS battery was charged after every cast without removing it from the rosette. A long charging cable was rigged so it was not necessary to swap the heavy batteries. Occasional venting of charging gases were necessary by unplugging the battery case at least once a day.

CalCOFI 0804JD CTD Data Processing & Console Ops Notes

Removed salt fliers on both primary & secondary comparisons.

No deep CTD casts (>515m) were performed on Leg 1 but 1000m casts were performed on Leg 2 on MBARI Line 67 (66.7) stations.

Only one O2 sensor was deployed, no ISUS, no Surface PAR, no pH. These were purchased in mid-2009 and first deployed on CalCOFI 0907M2 when a new 911+ system was bought.
V2 Deck unit was also purchased at that time so this cruise was on V1 Deck Unit - requiring Align-CTD offset of secondary conductivity (0.073sec).

Original hdr file on cast 001 & 002 require correction - normal fields were not setup before the 1st cast since a new version of Seasave was installed. It was fixed on cast 003. Casts 001 & 002 hdr files were edited during processing - note the .hex binary file has not been corrected on casts 001 & 002.
