abstract: This dataset includes dissolved inorganic carbon (DIC), total alkalinity and partial pressure of carbon dioxide (pCO2), nutrients, dissolved oxygen, particulate organic carbon and nitrogen (POC and PON), pigment concentrations from discrete water samples and colored dissolved organic matter (CDOM) from the profiling sensor. Data were collected during the Atlantic Zone Monitoring Program (AZMP). The AZMP was implemented in 1998 with the aim of increasing Fisheries and Oceans Canada's (DFO) capacity to understand and forecast the state of the marine ecosystem and to quantify the changes in the ocean physical, chemical and biological properties. Ocean acidification program was implemented across the AZMP in 2014 funded by the Aquatic Climate Change Adaption Services Program (ACCASP). This submission covers measurements conducted by BIO (the Maritime region, DFO) in the Scotian Shelf, encompassing from the Cabot Strait to the Gulf of Maine, during the period from 2014-09-19 to 2022-10-17.
purpose: To Increase Fisheries and Oceans Canada's (DFO) capacity to understand; describe; and forecast the state of the marine ecosystem and to quantify the changes in the ocean physical; chemical and biological properties(i). A critical element of the AZMP involves an observation program aimed at assessing the variability in nutrients; phytoplankton and zooplankton. The overall aim is to identify fundamental relationships among elements of the planktonic ecosystem and establish how they respond to changes in environmental drivers(i). The AZMP derives its information on the state of the marine ecosystem from data collected at a network of sampling locations (high frequency sampling stations; cross-shelf sections; and groundfish surveys) in each region (Quebec; Gulf; Maritimes; NL) sampled at a frequency of biweekly to once annually.

description: Parameter or Variable: Dissolved Inorganic Carbon; Abbreviation: TIC; Unit: umol / kg; Observation type: profile; Measured or calculated: measured; Sampling instrument: CTD and rosette bottle sampler: CTD model; sensors and other details to be specified in comment section; Analyzing instrument: SOMMA with UIC 5011 coulometer; Detailed sampling and analyzing information: Seawater samples were collected from standard depths in 500 mL borosilicate glass reagent bottles. Five mL of water was removed to allow room for thermal expansion and the sample was preserved within 30 minutes of collection with 0.1 mL of a mercuric chloride saturated solution; then sealed with Apiezon M grease and the ground glass stoppers secured in place with rubber bands. The samples were stored at room temperature until on-shore laboratory analysis. The samples were analysed for DIC using a SOMMA sample handling system in conjunction with a coulometer (UIC Inc.) to quantify total CO2 purged from the acidified sample.

description: Parameter or Variable: Partial Pressure of CO2; Abbreviation: pCO2; Unit: uatm; Observation type: profile; Sampling instrument: Niskin bottle; 10 L; Analyzing instrument: SRI 8610C gas chromatograph with flame ionization detector and methanizer; Detailed sampling and analyzing information: Seawater samples were collected in 160 mL volume crimp seal serum bottles; allowing the bottle to overflow by 3 volumes. The sample was immediately stabilised by the addition of 50 mL of saturated mercuric chloride solution; crimp sealed with a butyl rubber septum then stored in a refrigerator. Before analysis; a 11 mL headspace of 400 ppm CO2 in zero air was introduced into the bottle which was then thermally equilibrated at 22 °C for one hour. The bottle was then shaken vigorously for 8 minutes and the headspace displaced by a brine solution; flushing the sample loop of an SRI gas chromatograph equipped with a methaniser and flame ionisation detector. CO2 peaks were calibrated by injections of primary standard gas mixtures (Air Liquide) having CO2 mixing ratios of 397.3; 797.2; 1201 and 2017 ppm.; Uncertainty: 1 uatm; Quality flag convention: 1 = Sample drawn from bottle but analysis not recieved; 2 = QC Performed: Acceptable Measurement; 3 = QC Performed: Questionable Measurement; 4 = QC Performed: Bad Measurement; 5 = QC Performed: Not Reported; 6 = Mean of replicate measurements; 7 = Manual chromatographic peak measurement; 8 = Irregular digital chromatographic peak integration; 9 = Not sampled; Method reference: Dickson; A.G.; Sabine; C.L. and Christian; J.R.

code: carbon dioxide (CO2) gas analyzer
type: carbon dioxide (CO2) gas analyzer
description: measures gaseous carbon dioxide Carbon dioxide gas analyzer has often been referred to as LI-COR, because a lot of researchers choose to use products manufactured by LI-COR incorporation for their carbon dioxide measurement. The main component of a carbon dioxide analyzer is a nondispersive infrared (NDIR) spectroscopic sensors to detect CO2 in a gaseous environment by its characteristic absorption. Carbon dioxide (CO2) gas analyzer works together with carbon dioxide (CO2) equilibrator (insttypes_id 184) to measure carbon dioxide in the water. To measure water carbon dioxide, water needs to be continuously supplied to a showerhead inside an equilibrator. As the water flows through the equilibrator chamber, dissolved carbon dioxide exchanges quickly with air in the headspace. This air is then sampled by the carbon dioxide analyzer to determine the mole fraction of CO2 in water.
