|Summary:||CalCOFI 1607OS sailed from 10th Ave Marine Terminal San Diego July 10 2016 at 0800PDT and returned as scheduled July 27 2016. Offloading started upon arrival to San Diego. 68 stations (60 standard and 8 SCCOOS stations) were successfully occupied. Please refer to the preliminary data plots web page and data links below for preliminary data.
The typical 75-station summer station pattern was scheduled but due to high winds and rough seas west of Pt. Conception, ~ 26 hours were lost. All of Line 80 stations were completed but several stations on Line 77 were missed as ship-time ran out due to weather delays and long transit times. Stations missed: 77.100, 77.70, 77.60, 77.55, 77.51, 77.49, SCCOOS 85.8 35.8.

|General CTD Notes - data acquisition notes, logistics, processing - see below.
Please note that these regressions are generated from Final CTD vs bottle data and have gone through SIO-CalCOFI's strict data processing and point-checking protocol. CTD temperatures and salinities may not have changed from preliminary data but oxygen, estimated chlorophyll-a, estimated nitrate may change significantly after point-checking. Questionable or mistrip bottle data are removed from these comparisons but may be visible on the CTD.csv plots. For this cruise and future cruises, both primary & secondary sensor profiles vs bottle data will be generated and archived in the downloadable CTD+Bottle data files. These plots are under the "csv-plots\Primary" & "csv-plots\Secondary" subdirectories.

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. Please note that these plots are missing stations 80.80 & 80.70 due to bad weather. Anomaly data are not available on stations north of line 76.7 since they are typically only occupied on the Winter and Spring cruises, inconsistently.
