Table 1.
Physical characteristics and tracking details of the tracked loggerhead and green turtles tracked.
Table 2.
Summary of the six environmental variables measured in this study.
Table 3.
Mean value ± standard deviation of the six environmental variables measured at the transitional and foraging areas of each sea turtle.
Fig 1.
Summarized travel patterns of the sea turtles released at the coastal seas of South Korea.
White circles and squares with each color indicate start and end points, respectively. This map was generated based on GADM data (https://gadm.org/).
Fig 2.
Travel patterns and core habitat of the seven satellite-tracked loggerhead turtles.
Green zones indicate foraging areas calculated by 50 PVC. Dotted line areas indicate 50 PVC zones that were excluded from the core habitat. Dates marked with asterisks correspond to the year following the year of release. The red and blue arrows indicate the start and end dates of the tracking period, respectively. This map was generated based on GADM data (https://gadm.org/).
Fig 3.
Travel patterns and core habitat of the eight satellite-tracked green turtles.
Green and red zones indicate foraging and nesting areas calculated by 50 PVC, respectively. Dotted line areas indicate 50 PVC zones that were excluded from the core habitat. Dates marked with asterisks correspond to the year following the year of release. The red and blue arrows indicate the start and end dates of the tracking period, respectively. This map was generated based on GADM data (https://gadm.org/).
Fig 4.
Monthly changes in latitude, daily distance traveled, and six environmental variables (mean ± standard error) measured in the foraging areas of the both sea turtle species.
Table 4.
Comparison of the six environmental variables within and between species.
Interspecific differences were only compared in foraging areas corresponding to both species, while the columns with each species title indicate differences in the variables between the foraging and travel areas using t-test. Asterisk indicates significant differences (p-value < 0.05).

Travel routes and environmental variables on the travel route of two representative loggerhead turtles.
Green zones on the maps and the dotted sections in the graphs indicate core areas by 50 PVC. POC = particulate organic carbon. This map was generated based on GADM data (https://gadm.org/).

Travel routes and environmental variables on the travel route of two representative green turtles.
Green and pink zones on the maps and the dotted sections in the graphs indicate core areas by 50 PVC. POC = particulate organic carbon. This map was generated based on GADM data (https://gadm.org/).
