CalCOFI 1411NH General Cast Notes: This cruise occupied 75 stations: 66 standard, & 9 SCCOOS.  The station schedule was modified due to naval operations on lines 83 & 80 plus bad weather forecast. Refer to the map for the station order and cruise track. Coastal stations on line 83 & 80 (51, 50.5) & Santa Barbara Basin were done after lines 80 & 77 were completed.
CalCOFI 1411NH was on SIO RV New Horizon. Termination of the three conductor conductive wire was done by JRW using the 4-pin pigtail. Only the white conductor and shield were used for signal & ground.

CTD configuration was standard: Seabird 911+ with dual T, C, O2, & pumps;  Wetlabs C-Star 25cm transmissometer; Biospherical QSP200L PAR;  Datasonics/Benthos Altimeter; WET Labs ECO-AFL/FL; Seabird  pH; Satlantic ISUS v2 & battery. Please refer to the xmlcon files or cruise  prospectus for additional info.

Cast Notes:

Cast 01 - sat at depth while prodo bottle depths were calculated

Cast 03 - pressure offset of -0.05 was added pre-cast

Cast 05 - bottle #8 was replaced after cast - bottom cap problem; #18 bottom valve replaced - leaky

Cast 10 - ISUS not powered, no data; winch speed was over 60m/min for a brief time

Cast 11 - upcast different than downcast between 350-300m

Cast 12 - new ISUS battery installed - terminal was loose

Cast 17 - bottle #17 did not close, used #16 for prodo

Cast 22 - deep 3500m cast; PAR, ISUS + battery, pH sensors removed; O2 minimum at ~670m

Cast 23 - upcast different than downcast, especially O2; transmissometer zeroed on downcast @~375m, worked on upcast

Cast 26 - transmissometer dropped out below 400m, connector cleaned post-cast.

Cast 27 - ~2.5hr delay to sta 90.45, Naval ops; transmissometer dropped @415m on downcast

Cast 30 - transmissometer cut out @418m downcast

Cast 31 - personnel exchange before prodo station 90.28

Cast 35 - CTD landed on bottom due to misread of Knudsen, seems fine but terminal data may be influenced by suspended materials

Cast 36 - transmissometer outage at 453m downcast, upcast looks okay

Cast 37 - bottle #10 no closure, lanyard hung up

Cast 40 - transmissometer jumpy between 410-440m; rough weather, no net tows

Cast 41 - rough weather; PAR and pH caps left on, both caps came back, pH buffer replaced post-cast

Cast 42 - really rough weather, use loopedit to de-loop the slow ~27m/min downcast

Cast 44 - transmissometer voltage zeroed @~460m on downcast but back at 515m

Cast 45 - pressure offset -0.05 applied

Cast 46 - pressure offset -0.05 applied again, deck pressure often increases when CTD lands hard

Cast 48 - transmissometer out @~450m downcast

Cast 49 - 54 - transmissometer out below ~400m downcast, really need a backup

Cast 55 - calm night; transmissometer dropped after 450m

Cast 56 - 57 - transmissometer worked all the way!

Cast 58 - light rain during sample drawing; transmissometer good till ~470m downcast

Cast 59 - big rolls, ship rocking; primary oxygen bio-fouled on upcast from ~125m; sensor replaced post-cast

Cast 59 -61 - some deep noise in transmissometer

Cast 62 - transmissometer worked full cast

Cast 64 - ISUS battery not plugged in, no ISUS data; battery replaced after cast

Cast 65-66 - transmissometer outage @380m and again @465m

Cast 67 - 230m station; some strangeness on CTD acquisition PC, main plot went blank at 40m on upcast, data look fine but worth noting

Cast 68 - 60m shallow sta, big rolls

Cast 69 - SCCOOS sta 80.0 50.5, green water but not fluorescing much

Cast 71 - Santa Barbara Basin, wind causing wire angle; transmissometer noisy

File notes:
Seasoft-generated asc-hdr files were not renamed to YY-YYLLLLSSSS_###d or u.asc & .hdr. Voltages were not relabled. This practice makes it difficult to reprocess the CTD if necessary.
