Linear regression analyses. Linear regression analyses of the concentrations of POC, DOC, PBC, DBC, DIN, DIP, DON and DOP, as a function of salinity during the wet season. The regression lines (y = y0 + aS; where S is the salinity, y0 is the expected concentration at salinity = 0, and a is the slope of the regression line) have been fitted to the data (n = 28) obtained during the wet season (from May to September 2013) for the SML (dotted line, closed circles) and ULW (dashed line, open circles). The relationship between DBC and salinity (upper left panel) was exactly the same for the SML and ULW, and hence data were combined (dashed-dotted line). One value from the SML (star symbol) was excluded from the regression analyses for PBC, POC and DOC. DOI: https://doi.org/10.1525/elementa.255.f16
