Standard seabird processing steps were used. Pressure, primary and secondary temperature, primary and secondary conductivity, oxygen and fluorescence have been calibrated. Spikes in primary temperature and primary conductivity have been interpolated over and where needed secondary values (when available) have replaced the primary values. Derived variables, salinity, potential temperature, sigma-theta and sound velocity, were recalculated. Transmission, CDOM fluorescence, altimetry, RINKO oxygen and temperature, and ISUS have not been calibrated or have nominal calibrations as described below. CTD Pressure: The lab calibration was adjusted by applying +0.42dbar offset to the bias based on in-air surface readings of the CTD. CTD Temperature: The post-cruise lab calibration was used after comparisons with dual sensor and post-cruise calibration information. CTD Conductivity: The post-cruise lab calibration was adjusted after comparisons with dual sensor, expected deep water values and water sample data. There was a drift of 0.002mS/cm during the cruise. Over 8 groups, primary conductivity received offset of -0.0021 to +0.0003mS/cm. Secondary conductivity received an offset of -0.0047 to -0.0021 mS/cm. CTD Oxygen: Oxygen data were collected with a SBE43 sensor installed with pumped flow in-line after the primary temperature and conductivity sensors. A lag of -5 seconds was applied to oxygen voltage in the Seabird processing step Align. Downcast CTD oxygen voltage and upcast temperature and salinity were used to calibrate CTD to water sample oxygen (upcast). The 53 casts were fit as one group using bottles deeper than 500m. Fitting method followed Seabirds Application Note 64-2 (“SBE 43 Dissolved Oxygen Sensor Calibration and Data Corrections using Winkler Titrations”). A drift between casts was corrected using a linear fit to the residuals. A remaining pressure dependent shape in the residual between water sample and CTD oxygen was removed by subtracting a mean curve. The mean curve was made by stitching together sections using spline interpolation after finding the sections by fitting data from discreet pressure ranges. CTD Fluorometer: Data are from a Seapoint fluorometer with pumped flow in-line after the secondary temperature and conductivity sensors. Calibration with bottle data was performed using bottle chlorophyll values greater than 0.025mg/m3. The number of observations used were 115 out of 160 with a standard deviation of 0.04 mg/m3 in the residuals. Coefficients used: Slope:0.8975, Bias -0.0781. No time lag was applied. CTD Transmissometer: Data are from a WETLabs CSTAR DR transmissometer. Data are unprocessed, using calibration coefficients from 15 May 2008 to convert from volts. CTD CDOM Fluorometer: Data are from a WETLabs ECO CDOM FLCDRTD. They are unprocessed and given as raw voltage. See "Issue with Nitrate and CDOM sensors for casts 1 to 39" in Data Notes below. CTD Altimeter: Altimeter data are from a Datasonics PSA-916D and are unprocessed, using calibration from Mar 2005. CTD Nitrate: Data are from an ISUS Nitrate sensor. Sensor used on casts 1, 2, 8, 13, 16, 17, 19, 28, 32, 41, 48, and 53. Data are unprocessed. See "Issue with Nitrate and CDOM sensors for casts 1 to 39" in Data Notes below. CTD Oxygen and Temperature from RINKO III Sensor: These data are unprocessed. Data are not available on Casts 41, 48 and 53. CTD Surface Reference Photosynthetically Active Radiation (SPAR): Data collected using a Biospherical QSR-2200 starting on Cast 11. These data are nominal with applied calibration from 13 Mar 2007. Data Notes: Issue with Nitrate and CDOM sensors for casts 1 to 39. ------------------------------------------------------ There were initially problems with cross-talk between the CDOM sensor and the ISUS nitrate sensor that shared a cable and differential input connector on the CTD. The cross-talk introduced noise into the data for both sensors. To correct this, after Cast 39 the ISUS sensor was repositioned to a new CTD input connector and the CDOM cable changed. Associated with this change was an observed shift in the CDOM data of about +0.02V. After initial assessment of the data quality the following data were removed: - Casts 1, 2 and 8. CDOM Fluorescence data removed due to noise associated with cross-talk with nitrate sensor, data are not useable. - Cast 42. CDOM Fluorescence data removed since sensor’s cap was accidentally left on. - Cast 48. ISUS Nutrient data removed since data was of poor quality. Chemistry Sampling and Analysis Methods: ---------------------------------------- For further information see corresponding processing document in the DOC directory in folder "Individual Data Reports" Salinity samples were collected in 200 mL type II glass bottles with screw caps and disposable plastic inserts. On board, samples were analyzed in a temperature-controlled lab on a Guildline AutoSalinometer Model 8400B (SN: 69086), which was standardized with IAPSO standard seawater. Onshore, samples, 907 to 1146, were analyzed January 2010 in a temperature-controlled lab on the Guildline AutoSalinometer Model 8400B (SN: 69086), which was standardized with IAPSO standard seawater. Oxygen samples were collected in ~140 mL calibrated ground glass stoppered Erlenmeyer flasks and analyzed at sea using an automated Scripps Institution of Oceanography (SIO) Winkler-based UV titration system, consisting of laptop with LVO2 software (v2.34), 2 Brinkmann 665 Dosimats, pencil UV lamp, UV100BQ photodiode detector, mini stirrer with a water bath sample holder mounted on top, 2 Platinum Resistance Thermometers (PRT) to monitor solution temperatures, an analogue to digital converter to convert voltages from the detector and the 2 PRTs to a digital signal. The methodology followed was as described in the SIO Oxygen Titration Manual Version 10-Apr-2003. Nutrient samples (nitrate plus nitrite, silicate and orthophosphate) were collected in polystyrene test tubes. If analysis could be performed within 24 hours the samples were stored at 4 degree C, if not they were frozen at -20 degree C. All samples were analyzed fresh on board using a Technicon auto-analyzer following methods described in Barwell-Clarke and Whitney (1996). Ammonium samples were collected in 40.5 mL glass tubes, and analyzed on board following the Holmes et al. (1999) fluorometric protocol. Samples were kept in the dark for 5 to 8 hours at room temperature. Samples were then measured using a Turner Designs TD-700 fluorometer. Oxygen Isotopes Samples were collected into 30 ml glass vials. Once at room temperature, the caps were retightened and wrapped with parafilm for storage. Samples were analyzed at Oregon State University using the Thermo DeltaPlusXL mass spectrometer connected to a H2O-CO2 equilibration unit. Samples were analyzed June to July 2010 (10 to 11 months after collection). Dissolved Inorganic Carbon (DIC) and Alkalinity: DIC and Alkalinity were collected into 250 or 500 mL glass bottles. Samples were kept at 4 degree C until analysis and preserved with HGCL2. Samples were analyzed April 2010 (7 to 8 months after collection). Alkalinity ("Alkalinity:Total") and DIC ("Carbon:Dissolved:Inorganic") were measured from the same sample bottle at select stations. In addition, more frequent samples of Alkalinity were collected at most stations and have been labelled "Alkalinity:Total:Potentiometric" to distinguish this set of separate samples, even though both sets of Alkalinity samples were measured using potentiometric titration. DIC was analyzed at the Institute of Ocean Sciences using two systems, a SOMMA (Single- Operator Multi-Metabolic Analyzer) and a VINDTA - Coulometer systems to determine DIC. Samples were analyzed April 2010, 7 months after collection. Alkalinity samples were analyzed at the Institute of Ocean Sciences using an automated potentiometric titration system to determine the total alkalinity. Samples were analyzed April to August 2010, 7 to 10 months after collection. Total Chlorophyll-a (>0.7um) samples were collected into 2-L polyethylene bottles, immediately placed in dark bags and stored in a fridge. Samples were filtered onto 25 mm glass fiber filters (Whatman GF/F) under low vacuum filtration. If the sample could not be filtered immediately, the time taken until filtered was noted. Filters were stored in clear glass scintillation vials, kept in covered trays at -80C until analysis on shore. For analysis, samples were extracted in 90% acetone at -20C for 24 hours and analyzed on a Turner 10AU fluorometer, SN:5152FRXX, calibrated with commercially pure chlorophyll a standard (Sigma). Fluorescence readings taken before and after acidification were used to calculate chlorophyll and phaeopigment concentrations (Holm-Hansen et al 1965). Samples were analysed at IOS, March 2010, 6 months after collection. Phytoplankton and bacterioplankton were collected in 2 ml capacity cryogenic vial and fixed with 0.2 ml of 10% paraformaldehyde by vortex mixing. Samples were maintained for at least 15 min at laboratory temperature to allow fixation, and then stored at -80 degree C until analysis at the Bedford Institute of Oceanography. Cell concentrations of picophytoplankton, nanophytoplankton, and bacterioplankton (i.e. non-autofluorescent picoplankton) in thawed samples were analyzed by flow cytometry (Becton Dickinson FACSort) following protocols in routine use (Li and Dickie, 2001).
