Cruise Summary: | All 75 scheduled stations were successfully occupied although station sequence was re-ordered to occupy northern stations during calmer conditions. Warm, relatively calm ocean conditions seen in July persist supporting the prediction of a weakening 2014 El Nino. |

Please note that the anomalies are based on 50-year harmonics (1949-1999) and these data are 1m binavg Seasoft-processed CTD data that have not gone through thorough quality control checks or bottle corrections. They are presented to give a general impression of current conditions. Final data plots will be published after all data are processed.

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. 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: 12Mar2015 |

I. Overview
A. Brief Summary and Project Period - CalCOFI continues its 65-year hydrographic, fisheries, and ecosystem time-series survey of the Southern California Bight, occupying 75 stations. NOAA Fisheries will survey of the distributions and abundances of zooplankton, fish eggs & larvae plus their biotic and abiotic environments in the area of the California Current between Avila Beach, California and San Diego, California during the period of November 8 to November 25, 2014.
B. Service Level Agreements - Of the 18 DAS scheduled for this project, 2 DAS are funded by CCE-LTER II (NSF-OCE-BIO) and 16 DAS are funded by CalCOFI 2014/15 (NOAA-NMFS).
C. Operating Area - see map
D. Summary of Objectives - Ecosystem survey of the Southern California Bight, CalCOFI Lines 93.3 - 76.7. Oceanographic ecosystem survey, with biotic and abiotic components, of the California Current between Avila Beach, California and San Diego, California.
