Individual animals that first foraged near San Clemente, and
then migrated to the coast of Uruguay went through the frontal
area where the accumulation of anthropogenic debris was expected
to be the highest (Fig. 2b). On average, turtles likely encountered
a mean of 8.8 plastic items (hard plastic and bags) per square
kilometer of the overlapped foraging area. This quantity reached
maximum values of >100 items/km2 at the frontal area.
