CTD Processing Summary CalCOFI 2010SR CTD Preliminary Data

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.
CTD sensor corrections derived by comparing CTD sensor data, 4sec averages prior-to-bottle closure, to bottle samples
Dual T, S, & O2	Primary Sensor	Secondary Sensor
Salinity offset (bottle - CTD salinity; > 350m only; Seabird SBE4)	-0.0036	-0.0037
Oxygen ml/L (dual Seabird SBE43)	y = 1.0140x + 0.0542 R² = 0.9975	y = 1.0515x + 0.0110 R² = 0.9976
Oxygen umol/Kg (dual Seabird SBE43)	y =1.0134x + 2.6974 R² = 0.9970	y = 1.0524x + 0.7234 R² = 0.9969

Nitrate - ISUS 4sec ave voltage vs Bottle NO3 (Satlantic ISUS v3 SN111)	y = 30.2408x - 11.2874 R² = 0.9683

Summary:	CalCOFI 2010SR sailed on RV Sally Ride at 0800PDT 11 Oct 2020 from Nimitz Marine Facility San Diego. 71 of 75 stations were successfully occupied. CTD casts and Bongo/PRPOOS net tows were completed at each science station. Underway science included continuous pCO2/pH and meteorological measurements. Two expendable wave measuring drifters were also deployed. Due to science personnel restrictions related to social distancing requirements, no Manta/Pairovet net deployments or primary productivity experiments took place. Additionally, underway science including CUFES (Continuous Underway Fish Egg Sampler) and visual/acoustic observations of marine mammals and avifauna were not conducted during this cruise. The cruise ended at Nimitz Marine Facility San Diego on 24 Oct 2020 0800PDT.
