Satellite product and spatio-temporal resolution of environmental variables sampled underneath of loggerhead tracks. Table S2. Summary of the 65 satellite tracked juvenile loggerhead sea turtles in the North Pacific Ocean that displayed turn around behavior. Turtles were deployed within two regions: the Western North Pacific (Japan) and the Central North Pacific (CNP). Table S3. Model selection results from generalized additive modeling of the environmental conditions at the location of reversal in migration (‘turnaround’) versus the conditions experienced by a turtle as it continued to move eastward across the North Pacific Ocean. Presented are the p-values, r-squared, estimated degrees of freedom, and AIC for each of the eleven environmental parameters for (a) Japan deployed turtles and (b) turtles deployed within the Central North Pacific. Figure S1. Density histogram of maximum eastward longitude for (a) all turtles, n = 231 (gray), long-term tracks deployed off Japan, n = 34 (blue line), and long-term de...
