Dissolved inorganic carbon, total alkalinity, pH, temperature, salinity, dissolved oxygen, macronutrients, particulate organic carbon and nitrogen, collected from vertical profiles and discrete samples observations using CTD-Niskin rosette system from CCGS Teleost cruise (EXPOCODE 18TL20250804) during summer 2025 oceanographic survey from 2025-04-08 to 2025-04-26 (NCEI Accession 0311485)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 27, 2026 at 09:43 PM | Dataset Last Updated: January 13, 2026 at 12:00 AM
This dataset includes discrete sample and profile data collected during the CCGS Teleost Fisheries and Oceans Canada (DFO) Atlantic Zone Monitoring Program (AZMP) cruise (EXPOCODE 18TL20250804) in the North Atlantic Ocean and Labrador Sea from 2025-04-08 to 2025-04-26. 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.
