We began with a maximal model that included: (1) a time variable ( t , weeks since the beginning of the study) to test for an overall trend; (2) sine and cosine components to test for seasonality [ 35 ]; (3) an interaction between t and the seasonal components to test for variation in the amplitude of the seasonal cycle; and (4) weekly survey effort (i.e. number of hours with at least one observer in the water).

Weekly shark abundance showed a positive trend over time as well as a pronounced seasonal cycle, with the seasonal amplitude increasing over three years ( figure 3 a , table 1 ).
