The following Corrigendum aims to rectify our original paper as strings of text from certain articles were quoted therein without giving full credit to the authors of those articles. In fact, we highly respect these authors and very much regret leaving out the references.

‘Considerable efforts have been made in different systems in order to quantify k, which is the parameter in eq. (1) most prone to errors (Raymond and Cole, 2001) and primarily controlled by turbulent mixing on the water side of the air-water interface (Wanninkhof et al., 2009)’.

‘Beaulieu et al. (2012) point out that considerable efforts have been spent in different systems on quantifying k, which is too prone to errors to be definitely determined in equation (1) (Raymond and Cole, 2001) and primarily controlled by turbulent mixing of the air-water interface (Wanninkhof et al., 2009)’.

‘Both sheer stresses at the riverbed and wind at the water surface result in turbulence at the air-water interface in large rivers (Beaulieu et al., 2012).’

‘However, the large heterogeneity of aquatic systems raises questions about the appropriateness of using a single wind-based model to predict k in all aquatic systems (Vachon and Prairie, 2013).’

‘The existence of a unique and universal wind–k relationship for all aquatic systems is highly questionable given that for any wind speed, its effect on gas exchange is unlikely to be the same in the ocean and, for example, in a small kettle lake.’

should be

‘There is no universal wind–k function which can describe gas exchange in all aquatic systems (Vachon et al., 2010)’.

‘where C10 equals the surface drag coefficient for wind at 10 m (1.3×10−3) (Stauffer, 1980); kc equals the von Karman constant (0.41); and z is the height of wind speed measurement (meter) above the water surface’.

‘To compare the exchange coefficient for different gases and at different water temperatures, the gas transfer velocity was normalized to a Schmidt number of 600 (Sc=600, for CO2 at 20°C) with the following equation (Jähne et al., 1987)’.

‘Measured gas flux was up to five times higher when heat was being lost from the surface layer of an arctic lake and wind speeds were low than when wind speeds were 5 m s−1 (Macintyre et al., 2001)’.

‘On clear days, there is sufficient light for high rates of photosynthesis, and dissolved oxygen concentrations normally are high. On cloudy day, photosynthesis is limited by insufficient light, and dissolved oxygen concentrations often are low (Table 1). The probability of dissolved oxygen depletion is much greater during nights following cloudy days than during nights following clear days (Boyd and Tucker, 1998)’.
