Surface underway pH, water temperature, salinity, dissolved oxygen, chlorophyll and discrete analyses of dissolved inorganic carbon and total alkalinity from the underway TSG collected during the RRS Discovery fall 2023 oceanographic survey cruise (EXPOCODE 32V320231006) in the North Atlantic Ocean and Labrador Sea from 2023-10-06 to 2023-10-26 (NCEI Accession 0299020)

This dataset includes underway sensor measurements collected during the RRS Discovery Fisheries and Oceans Canada (DFO) Atlantic Zone Monitoring Program (AZMP) cruise (EXPOCODE 32V320231006) in the North Atlantic Ocean and Labrador Sea from 2023-10-06 to 2023-10-26. These data include water temperature, salinity, dissolved oxygen, and chlorophyll a fluorescence. In addition, daily sampling for measurement of DIC and TA were conducted. Oceanographic sampling of physical, biological, and chemical parameters is performed annually along selected fixed sections as part of the AZMP. The full sampling program 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.
