        abstract:  This dataset includes discrete sample and profile data collected from MARTHA L. BLACK in the Davis Strait, Labrador Sea and North Atlantic Ocean from 2012-06-01 to 2012-06-17. These data include AMMONIUM (NH4), CHLOROFLUOROCARBON-12 (CFC-12), DISSOLVED INORGANIC CARBON (DIC), DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRATE, NITRITE, SALINITY, SULFUR HEXAFLUORIDE (SF6), TOTAL ALKALINITY (TA), WATER TEMPERATURE, pH, phosphate and silicate. The instruments used to collect these data include Alkalinity titrator, CTD, Coulometer for DIC measurement and bottle. These data were collected by Igor Yashayaev and Kumiko Azetsu-Scott of Bedford Institute of Oceanography as part of the CLIVAR_AR07W_2012 data set. CDIAC associated the following cruise ID(s) with this data set: MLB2012001 The International CLIVAR Global Ocean Carbon and Repeat Hydrography Program carries out a systematic and global re-occupation of select WOCE/JGOFS hydrographic sections to quantify changes in storage and transport of heat, fresh water, carbon dioxide (CO2), and related parameters. The World Ocean Circulation Experiment (WOCE) was a major component of the World Climate Research Program with the overall goal of better understanding the ocean's role in climate and climatic changes resulting from both natural and anthropogenic causes. The CO2 survey took advantage of the sampling opportunities provided by the WOCE Hydrographic Program (WHP) cruises during this period between 1990 and 1998. The final collection covers approximately 23,000 stations from 94 WOCE cruises.
        purpose:  This dataset is available to the public for a wide variety of uses including scientific research and analysis.

                description:  Parameter or Variable: Dissolved Inorganic Carbon; Abbreviation: DIC; Observation type: discrete; In-situ / Manipulation / Response variable: In-situ observation; Measured or calculated: Calculated; Detailed sampling and analyzing information: Total inorganic carbon (TIC) and total alkalinity (TA) were not measured during the 2012 Labrador Sea Mission because of laboratory space constraints on the CCGS Martha L Black. Instead, water samples for combined TIC and TA analysis were collected in 500 mL borosilicate glass reagent bottles and preserved by the addition of 100 μL of saturated mercuric chloride solution. A 5 mL headspace was created in each sample before sealing the bottles with greased glass stoppers held in place with rubber bands. The samples were transported back to BIO for analysis.; Standardization description: Around 470 water samples for TIC and TA analysis were collected from stations 1 - 28 on the AR07W line with the exclusion of Station 26. The sample identification numbers fell in the range 380025 to 380621..

                description:  Parameter or Variable: pH; Abbreviation: pH; pH scale: Total Scale; Observation type: discrete; In-situ / Manipulation / Response variable: In-situ observation; Measured or calculated: Measured; Detailed sampling and analyzing information: Water samples were collected and analysed for pH in 2012 on board the CCGS Martha L Black by Melissa Wartman. Two significant changes were made to the pH sampling protocol for the 2012 Labrador Sea Mission. First, 60 mL borosilicate glass tubes with screw caps were used to collect seawater samples rather than the amber Boston Round soda lime glass bottles used in previous missions as there is evidence to suggest that seawater pH is not stable in samples that are stored in soda lime glass. Second, the samples were analysed fresh or stored for a maximum of around 12 hours before analysis. Mercuric chloride was not used to poison the samples this year as further experiments are required to establish whether the addition of mercuric chloride can affect the pH of seawater. The spectrophotometric analytical method is described in “Guide to best practises for ocean CO2 measurements” SOP 6B, edited by Andrew Dickson. Briefly, racks of tubes containing seawater samples are placed in a water bath for around 30 minutes to bring the samples to 25 °C. A sample is then introduced into a water-jacketed 10 cm quartz cell and 30 μL of the indicator dye m-cresol purple is added before mixing well. The absorbance of light at the wavelengths 434 and 578 nm is measured with an Agilent photodiode array spectrophotometer and the resulting extinction coefficients at these wavelengths are used to determine the pH of the sample. The sample absorption spectra are referenced to measurements of a Certified Reference Material obtained from Scripps University and consisting of TRIS buffer in synthetic seawater with a known pH accurate to four decimal places. The analytical precision was 0.07% as determined by multiple measurements of seawater drawn from 14 Niskin bottles fired at the same depth..

            description:  measures dissolved inorganic carbon (DIC) 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 by absorbing the CO2 in an absorbent. The pH of the solution is monitored by measuring the transmittance .
