description: 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 deployments in the Central North Pacific, n = 31 (green line). Figure S2. Examples of east-west movement in individual long-term tracks. Example of 2 turtles deployed in the western (a) and (b) central North Pacific that reached a maximum eastward trajectory and changed dominant direction. Panels c and d show each track moving in an east-west-east direction, with the start location designated by a blue triangle and final location designated with a red square. Both tracks initially moved eastward (gray line) and then reversed direction, moving westward (blue segment of track). Both changed dominant direction for second time, once again moving eastward (green segment of track). Track ‘68330’ transmitted for 614 days (15,289 km). Track ‘22534’ transmitted for 1047 days (18,238 km). Figure S3. (a) Average sea-surface temperature (SST °C) and (b) Chlorophyll-a concentrations (mg m-3) for the North Pacific Ocean basin, from 1997 to 2014). Figure S4. GAM response curves of juvenile loggerhead east-west movements. Positive values show the likelihood of an animal reversing direction under a range of environmental values. Results indicate that turtles deployed off Japan are more likely to reverse direction with an increase in declination (a) and the longer it travels since deployment (b). For the turtles deployed in the Central North Pacific, turtles are more likely to reverse direction under lower values of magnetic field inclination (c) and during the first half of the year (d). Gray shading represents the 95 % confidence intervals for the fitted relationships. (DOCX 1198 kb)
