The 7th Chinese Arctic Research Expedition targets on the global climate change and the correlations of sea ice variation, as well as its effects on the environment and ecosystem in Arctic Ocean. The major studies are focused on physical oceanography, marine chemistry, marine geology and marine ecology. The objectives of the studies are: 1) Investigation of primary path of pacific waters and land-derived fresh waters input to Canada Basin; 2) Observation on marine chemical parameters in Arctic Ocean and the influences on cycling of biogeochemistry. 3) Identification of plankton species and bio-diversity in Arctic area.

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.

The 8th Chinese National Arctic Scientific Research Expedition (8th CHINARE) voyaged within the U. S. Exclusive Economic Zone from 20 to 25 September 2017, traversing the Bering and Chukchi Seas. The objectives of the 8th Chinese National Arctic Scientific Research Expedition were to improve understanding of basic environmental information of marine hydrology and sea ice variation in summer 2017 in areas of the Bering Sea, Chukchi Sea, Chukchi Sea Rise and Canadian Basin, and to provide basic information for global climate change research. Data sets of fundamental environmental parameters (temperature, salinity, depth, nutrients and Chlorophyll a (Chl a), the abundance of bacterioplankton, and records of benthic macroinvertebrates and demersal fish were obtained within this zone.

This dataset contains salinity-calibrated Conductivity Temperature Depth (CTD) and bottle data from the 2021 Ocean Observatories Initiative (OOI) Irminger Sea 8 cruise of the research vessel Neil Armstrong (AR60-01). Data quality control methods have been used to assess performance of the CTD instrument. Resulting high-quality profiles were then used together with salinity bottle data analyzed at sea to create a post-cruise salinity-calibrated CTD product. This submission has been produced as part of an ongoing effort to more fully utilize CTD data collected by OOI Irminger cruises, which have been taking place annually since 2014. The hydrographic data collection facilitated by OOI in the Irminger Sea currently supports science for not only OOI end users, but also international oceanographic research projects, including the Overturning in the Subpolar North Atlantic Program (https://www.o-snap.org/), Atlantic Meridional Overturning Circulation Program (https://usclivar.org/amoc) and BioGeoChemical Array for Real-time Geostrophic Oceanography program (https://biogeochemical-argo.org). Such programs require a higher-level data product than what OOI provides through its standard data dissemination, and hence a quality controlled, salinity-calibrated data product has been produced. Data are in text format, data description is in PDF.
