Conceptual diagrams of the fjord surface water \(\hbox {pCO}_{2}\) evolution and its drivers in Sherard Osborn Fjord (a) and Petermann Fjord (b). Local variation on a fjord scale is mainly controlled by the freshwater inputs and the subsequent high stratification as shown by the results of a number of 1D dynamic simulations (c-d). Modeled \(\hbox {pCO}_{2}\) (curves with the color matching the wind speed ranging between 2 m \(\hbox {s}^{-1}\) and 10 m \(\hbox {s}^{-1}\)) with initial values (black crosses) and model settings derived from the average observations at the temperature minimum layer (TML) in Sherard Osborn Fjord (c) and Petermann Fjord (d). Days since ice retreat (DSR) for \(\hbox {pCO}_{2}\) simulations were negative before the sampling time (DSR = 0) corresponding to the period of sea-ice melt and positive after the sampling time corresponding the period of post sea-ice melt. The horizontal line is the atmospheric \(\hbox {pCO}_{2}\).
