Estimated contributions of physical processes and nutrient input to hypoxia. Water transports for the Gotland Basin deep water (A), annual fluxes of total apparent oxygen utilization (TAOU) (B), and TAOU in the deep water, estimated (5-y moving average; Fig. 1P) and adjusted by subtracting variations in lateral transports and vertical mixing (C). Nitrogen input from land and atmosphere was used to describe the oxygen consumption; similar plots using phosphorus inputs are shown in Fig. S6.
