Project: CalCOFI 1708SR (UNOLS SR1712) on SIO RV Sally Ride
Summary: CalCOFI 1708SR sailed on SIO RV Sally Ride at 1000PDT 01Aug2017 from Nimitz Marine Facilities (MarFac) San Diego. Returning to San Diego 0930PDT 16Aug2017, RV Sally Ride was offloaded upon arrival to MarFac. All 73 scheduled stations - 65 standard stations & 8 SCCOOS 20m stations were occupied (see station map). As planned, two stations were dropped - 93.3 120 & 91.7 26.4 - to complete the scheduled stations plus mooring deployment. To maximize ship transit efficiency, saving 10+hrs, RV Sally Ride sailed north after sta 83.3 51.0 to sta 80.0 60.0. With the mooring deployment scheduled for sta 80.0 55.0, this station was scheduled after sta 76.7 49.0 & the pickup of Uwe Send's mooring team at Avila Beach. Eight in-shore stations off Santa Barbara & Ventura were occupied after sta 80.55, as we transited south - see map below for actual cruise track. Please refer to the preliminary data plots web page and data links below for preliminary data.
In addition to DIC, pH, NCOG sampling, 1708SR included oxygen stable isotope seawater samples collected on 18 stations (see map for station sampled).

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.

General CTD Notes - data acquisition notes, logistics, processing - see below.
Please note that these regressions are generated from preliminary CTD vs bottle data and will be reprocessed once final bottle data are available. CTD temperatures and salinities do not usually change 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.
