Abstract
This data set is a collection of publicly available hydrographic and geochemical observations in and around the Nordic Seas, within the domain 50-90˚N and 45˚W-45˚E, over the period 1950-2019. It consists of vertical profiles of temperature, salinity, oxygen, nitrate, and phosphate mainly collected by shipboard CTDs and water bottles, as well as Argo float profiles. All observations were combined into a single data set and quality controlled as described in Brakstad et al., (2023) (https://doi.org/10.1016/j.pocean.2023.102981). The quality control involves removing duplicates between the source archives, erroneous profiles, density inversions, and outliers. The final quality-controlled data set consists of 608 804 hydrographic profiles and 330 026 geochemical profiles, that can be easily accessed for any water mass analyses in the Nordic Seas.
