The study sites included six different fjords located in an area spanning from 56.6˚N to 66.6˚N and from −39.0˚W to 13.7˚E. All data were collected throughout five cruises from April to July 2023, with instruments installed on R/V Skagerak (University of Gothenburg). N2O dissolved in the surface water was measured continuously via Cavity Enhanced Absorption Spectroscopy using a LI-7820 N2O/H2O trace gas analyzer (LI-COR Biosciences). The LI-7820 produced high-precision N2O (ppb) measurement data every second, response time of 0 to 330 ppb ≤ 2 seconds and a maximum drift of < 1 ppb per 24-hour period. LI-7820 recorded timestamped measurements (>1800 measures were recorded in each fjord) were subsequently averaged (integrated) over 30 min to make data analysis feasible (Table 1). N2O measurements were then adjusted by pushing back the data by 20 minutes to account for headspace equilibration response time and for the time it takes to the water to travel from the sea to the exchanger itself. The ship was ...
