Abstract
Natural light is an important dispersal cue for marine turtle hatchlings, therefore artificial light may have major impacts. This thesis investigated the effect of artificial light and oceanography on the in-water movement of flatback turtle hatchlings. Hatchlings were attracted to and lingered around artificial lights and the impact varied with light type. Predation of hatchlings was highest near a jetty as it sheltered and concentrated predators. Hatchling oriention was influenced by waves and currents, but the effect of the latter was reduced when light was present. These results provide rare data to implement light mitigation to protect these threatened species.
