Model scores: GAMMs are $Z_{\mathit{shark}}\sim s\left(T,i,m,e,,,k,=,5,,,b,s,{=}^{\prime },c,c^{\prime }\right)+Ptt$, where Z_shark is the depth location of the shark at any given time expressed in rounded hours (Time), k defines the degrees of freedom and s is the Gaussian smoother function. Ptt Tag Identifier/Shark, df degrees of freedom, SE Standard Error, p p value.
