Figure 1. Time series of daily temperature observations at Langara Island Lighthouse. Positive anomalies from the average temperature of the entire record are shown in red, negative in blue (from Chandler 2016)
Figure 2. Time series of daily Sea Surface Temperature. Blue areas represent temperatures that are below normal, red areas represent temperatures that are above normal. Normal means an average (blue line) of all observations and the dashed blue lines show one standard deviation from the average. The black dots show the maximum and minimum temperature observed for each day of the year (from Chandler 2016).
