Norwegian West Coast OA Timeseries 2025

Ocean acidification timeseries of full water depth stations at the Norwegian west coast. Discrete samples of inorganic carbon (DIC), total alkalinity (TA), nutrients, and hydrography. The data are collected during the period December 2024 to October 2025 (7 cruises). The data represent a continuation of timeseries started in 2007. The research vessel Hans Brattstrøm has been used to collect the water samples, which are analysed for DIC, TA, and nutrients. Dicrete samples for salinity and oxygen are also collected from teh deepest water and used to calibrate the hydrography and oxygen sensors. An RBR sensor is used for hydrographic measurements. Empty cells are marked with "-999".
