attribute NC_GLOBAL comment String pH was measured on the total hydrogen scale (pHT) within one hour of sample collection. Each water sample was placed in a 25 degrees C water bath for 10–20 minutes to standardize temperature (mean temperature over all pH measurements of 22.2 +/- 2.6 degrees C). pHT was then measured in duplicate using the Orion 5 Star pH meter and glass electrode (ROSS Ultra pH/ATC Triode 8107BNUMD) calibrated with Tris–HCL buffer solution obtained from the Dickson Lab (Batch 22). Electrode performance was regularly checked against standard Tris-HCl and AMP-HCl buffers in artificial seawater (Nemzer et al. 2005; Dickson et al. 2007). Temperature was measured using the integrated temperature sensor on the ROSS Ultra pH/ATC Triode from 2010–2013, and using a handheld thermocouple (Omega HH81A) in 2014. Total alkalinity (TA) was measured in triplicate by acid titration on a Mettler–Toledo DL15 autotitrator using 0.1 mol L–1 HCl buffered in 0.6 mol L–1 NaCl (modified from SOP 3b, Dickson et al. 2007). The autotitrator was calibrated daily on the NBS scale using certified reference buffers (Orion), and certified reference materials (Dickson Lab, batches 138 and 141) were measured periodically to ensure accuracy (within +/- 10 umol kg-1). CO2SYS software (Pierrot et al. 2006) was used to correct pHT values for in situ temperature and pressure, and to calculate the entire carbonate system from TA, pHT, temperature, salinity, and pressure. For all calculations, we used the carbonic acid constants (K1 and K2) of Mehrbach et al. (1973) refitted by Dickson and Millero (1987), and the aragonite solubility product (Ksp) from Mucci (1983). The effects of nutrients (phosphate and silicate) on the carbonate system were assumed to be negligible (eg. Cai 2003; Yates and Halley 2006). TA and dissolved inorganic carbon (DIC) values were corrected for in situ salinity values using the mean salinity of all sites (35.3 psu) to yield salinity-normalized TA (nTA) and DIC (nDIC). CTD data (temperature, salinity, pressure, and dissolved oxygen) were collected both as water column data from ship deployments and as bottom–water data from a vehicle–mounted CTD. In all years, a SBE 9/11+ CTD was used for water column measurements, while vehicle-mounted CTD usage varied by year: SBE 19 (2010), SBE 37-SI (2012), and SBE 49 (2013, 2014). All dissolved oxygen measurements were collected using a SBE 43 dissolved oxygen sensor. CTD and dissolved oxygen measurements were vertically binned every meter in order to smooth water column profiles prior to additional analyses.
