Ericson, Y., Chierici, M., Falck, E., Fransson, A., Jones, E., Kristiansen, S., 2019. Evolution of the marine CO2 system in a West Spitsbergen fjord with emphasis on seasonal drivers of the calcium carbonate saturation state.

Marine CO2 system data (total alkalinity and pH on the total scale) were collected from 5 to 8 discrete depths on a close to monthly basis at the IsA station (N 78°16.0, E 15°32.0, bottom depth: 95 m) between March 2015 and November 2017. The station is located at the opening of Adventfjorden, a side-branch of the larger Isfjorden system on the west coast of Spitsbergen. The seawater samples were collected using a Niskin bottle following standard procedures and analyzed at UNIS (Longyearbyen, Norway). Total alkalinity was determined using a non-purged open cell potentiometric titration (Metrohm© Titrando system, Switzerland), with a precision typically about ± 2 µmol kg-1. The accuracy was set by the use of Certified Reference Materials (purchased from A. Dickson, Scripps Institution of Oceanography, USA). pH was determined using a diode-array spectrophotometer and the unpurified indicator dye m-cresol purple (mCP) following the method of Clayton and Byrne (1993). The perturbation of the sample pH due to the addition of the indicator dye was corrected for according to Chierici et al. (1999). The precision was generally around ± 0.001. Description of the analytical methods can be found as a summary in the data file. The fieldwork was funded by the Norwegian Research Council under Arctic Field Grant (RiS #: 10127; 10404; 10662), with additional fieldwork support from the University Centre in Svalbard (UNIS) and the Ocean Acidification flagship program within the FRAM- High North Centre for Climate and the Environment, Norway (A. Fransson, M. Chierici).
