These data include water temperature, salinity, dissolved oxygen, nutrients, dissolved inorganic carbon (DIC), total alkalinity (TA), pH, and other parameters. Oceanographic sampling of physical, biological, and chemical parameters is performed annually along selected fixed sections as part of the AZMP. The sampling consists at a minimum of a vertical profile of the entire water column (temperature; salinity; dissolved oxygen); rosette bottle casts at selected depths (nutrients; DIC and TA; and other biological parameters) as well as plankton net tows. The AZMP was implemented in 1998 with the aim of increasing DFO's 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. Ocean acidification is an emerging priority for DFO under the Aquatic Climate Change Adaption Services Program (ACCASP) and is developing the knowledge-base necessary to support the development of adaptation tools and strategies and investing in science to better understand the specific consequences of a changing climate. Specifically, the effects of ocean acidification on ecosystems in the Northwest Atlantic and large aquatic basin risk assessments consider ocean acidification at the basin and sub-basin scale are being investigated.

NOAA National Centers for Environmental Information custodian carbon dioxide (CO2) gas analyzer carbon dioxide (CO2) gas analyzer 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.
