Scatter Plot from Scientific Research

Annual median bottom-water oxygen concentrations in the first 3 weeks after ice-off by logarithmic lake surface area class. GAM smooths were weighted by inverse variance to account for uncertainty at low sample counts. Shaded areas represent 95% CIs. Legend labels define area class boundaries (for example, green marks A surf = 10 2 10 3 ha). Dashed and dotted lines mark hypoxia (DO < 2 mg l -1 ) and anoxia (DO < 0.5 mg l -1 ), respectively.
