General notes: Station Pattern & Cruise Track

CalCOFI 0903JD March 7 - 24 2009, San Diego to San Francisco

Cruise and CTD Data Processing Notes

CalCOFI 0903JD was CalCOFI's last cruise on NOAA RV David Starr Jordan since the ship will be decommissioned before our next winter cruise. (CalCOFI will sail on RV Ocean Starr, Staubert Marine's refurbished/retrofitted David Starr Jordan in July 2012).
RV Jordan was loaded at MArFac. San Diego March 5th - 6th & offloaded in San Francisco March 24th.

Seabird 911+ configuration:
Primary Temperature (#1324), Conductivity (#042206), and O2 sensor (#431075), pumped (#55060); Secondary Temperature (#2533), Conductivity (#357) pumped (#52236); Wetlabs (CST-479DR) 25cm transmissometer (mislabeled Chelsea/Seatech in con); Seapoint chlorophyll fluorometer (SCF2483 @10x); Benthos/Datasonics Altimeter (#46604); MBARI-ISUS v1 (#111); no surface PAR was installed.
(Freq0=T0; Freq1=C0; Freq2=Pr; Freq3=T1; Freq4=C1; V0=Trans; V1=Fl; V2=Alt; V3=ISUS; V4=O21; V5=open; V6=open; V7-open)

Logistics:
We completed 63 standard stations and 8 SCCOOS stations before transiting north to offload in San Francisco. The last three stations on Line 76.7 (77) were dropped due to rough weather and lack of ship time: 76.7 55.0, 76.7 51.0, 76.7 49.0; SCCOOS sta 88.5 30.1 was also dropped due to lack of ship time.
Typical Spring stations north of line 76.7 (77) were occupied by FV Frosti which sailed from San Francisco 16 Apr to San Diego 09 May (see DEPM 0903FR for more info). Standard CalCOFI seawater analyses were performed on all depth sampled. The Jordan tied up in San Francisco and was offloaded onto trucks for equipment transport back to San Diego.

CalCOFI 0903JD CTD Data Processing & Console Ops Notes

Bottle NO3s drifted up and were questionable until a mid-cruise fix. The data required a baseline shift. ISUS showed the bottle data had a distinct shift-drift over time. See pdf figures.

Removed salt fliers on both primary & secondary comparisons.

No deep CTD casts (>515m) were performed this cruise since RV David Starr Jordan does not have enough winch wire
