This NCEI Accession consists of dissolved inorganic carbon, total alkalinity, pH, temperature, salinity and other variables collected from profile and discrete sample observations during CCGS Teleost mission cruise 18TL21012 (EXPOCODE 18TL20210602) in the Gulf of St. Lawerence and St. Lawrence River, North Atlantic Ocean from 2021-06-02 to 2021-06-12. Oceanographic sampling of physical, biological and chemical parameters was performed biweekly at selected fixed stations and two to three times annually along selected fixed sections, as part of the Atlantic Zone Monitoring Program (AZMP). The sampling consists at minimum of vertical profile of the entire water column, water bottle sampling at selected depths of nutrients, salinity and oxygen, vertical net tows for zooplankton. See: http://science-catalogue.canada.ca/record=b3951030~S6 for more details.

This data package contains underway total alkalinity, water temperature, salinity and other variables collected from surface seawater during the R/V Atlantis Atlantic Zone Monitoring Program (AZMP2022) cruise (EXPOCODE 33AT20220319) in U.S. and Canadian East Coast waters and the Labrador Sea, North Atlantic Ocean from 2022-03-19 to 2022-05-16. Data were collected from the ship's underway seawater supply during a transit from Woods Hole MA to Greenland. This effort was part of the jointly-funded NOAA-DFO grant entitled "Improving Regional Northwest Atlantic Observations Through Enhanced Collaboration". Along with total alkalinity, corresponding temperature and salinity measurements are included.

Cruise 449/1 by research vessel Oceanus in July 2008 had the objective to service a number of moored platforms for the Northwest Tropical Atlantic Station (NTAS) and Meridional Overturning Variability Experiment (MOVE) projects. To calibrate and validate the mooring data, CTD casts with salinity water samples were collected; these data are reported here. The CTD salinity data have been quality-controlled and adjusted using the water sample data. The raw CTD data files are included in this archive as well and contain other parameters such as oxygen, optical attenuation, and fluorescence, which are not thoroughly calibrated. The data format is NetCDF.

Dataset consists water temperature, salinity, and other parameters of netCDF files of downcast CTD data collected at 79 CTD stations on the Scotian Shelf and in Gulf of Maine in spring 2024. This cruise is U.S. State Department MSR U2024-007 as part of the World Data Service for Oceanography.

This dataset includes chemical, discrete sample, physical and profile data collected from L'ATALANTE in the Caribbean Sea and North Atlantic Ocean from 2003-04-12 to 2003-04-25 and retrieved during cruise CARIBINFLOW and CARINA_35A320030412.

These data were collected by Monika Rhein and Reiner Steinfeldt of Universität Bremen, Institut für Umweltphysik as part of the CARINA_35A320030412 dataset. The CARINA (CARbon dioxide IN the Atlantic Ocean) data synthesis project is an international collaborative effort of the EU IP CARBOOCEAN, and U.S. partners. It has produced a merged internally consistent dataset of open ocean subsurface measurements for biogeochemical investigations, in particular, studies involving the carbon system. The original focus area was the North Atlantic Ocean, but over time the geographic extent expanded and CARINA now includes data from the entire Atlantic, the Arctic Ocean, and the Southern Ocean.

This dataset includes discrete sample and profile data collected during the CCGS Hudson, R/V Coriolis II, CCGS Teleost, RRS James Cook and Fugro Discovery Atlantic Zone Monitoring Program cruises in the North Atlantic Ocean and Labrador Sea from 2014-11-16 to 2020-12-01. These data include water temperature, salinity, dissolved oxygen, nutrients, dissolved inorganic carbon (DIC), total alkalinity, pH on the total scale, and ammonium. The Atlantic Zone Monitoring Program (AZMP) was implemented in 1998 with the aim of increasing 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. Ocean acidification is an emerging priority for Fisheries and Oceans Canada under the Aquatic Climate Change Adaption Services Program 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.
