Samples were collected from the surface layer, treated with 0.1 µL of HgCl2, stored on ice, and transported to the University of Delaware for DIC and TAlk analysis. Data is used to calculate pCO2 and compared to moored observations for internal consistency and validation of time series observations.

Samples for DIC, TA and pH were collected without bubbling into 125-ml groundglass bottles with greased stoppers. Bottles were overflowed 2.5 times the volume before the sample was collected and preserved with 0.1 ml of saturated mercuric chloride solution, and immediately cooled. Samples were generally stored for about a week before analysis. DIC was measured first from each sample bottle, followed sequentially by pH and TA. DIC of unfiltered water was determined using an automated analyzer built by Apollo SciTech. Immediately after opening the sample bottle, a digital syringe withdrew a small amount of sample (1.0 mL), acidified it with 10 % phosphoric acid and subsequently measured the evolved CO2 with a Li-Cor 7000 non-dispersive infrared gas analyzer.; Replicate information: no replicates; CRM manufacturer: Dickson Lab in Scripps Institution of Oceanography; Preservation method: HgCl2; Preservative volume: 0.1 micro liters; Researcher name: Scott Noakes; Researcher institution: University of Georgia Parameter or Variable: Total alkalinity; Abbreviation: TA_UMOL_KG; Unit: micro-mol/kg; Observation type: Surface discrete measurement; Measured or calculated: measured; Sampling instrument: Underway flow-through system; Analyzing instrument: Apollo alkalinity titrator AS ALK-2; Type of titration: Gran Titration; Cell type (open or closed): open; Detailed sampling and analyzing information: Discrete samples were collected from the onboard flow through-system and transferred to sample bottles through silicone tubing to prevent bubbling.

NOAA National Centers for Environmental Information custodian Non-dispersive infrared (NDIR) dissolved inorganic carbon (DIC) analyzer Non-dispersive infrared (NDIR) dissolved inorganic carbon (DIC) analyzer A known amount of seawater is dispensed into a stripping chamber where it is acidified and purged with an inert gas. The amount of CO2 in the resulting gas stream is determined with a non-dispersive infrared (NDIR) carbon dioxide analyzer. spectrophotometer spectrophotometer spectrophotometer, optical spectrometer, spectrograph or spectroscope An optical spectrometer (spectrophotometer, spectrograph or spectroscope) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials.
