The impacts of artificial light on marine turtles

Pendoley K. & Kamrowski R. L. (2015) Influence of horizon elevation on the sea-finding behaviour of hatchling flatback turtles exposed to artificial light glow. Marine Ecology Progress Series 529, 279-288.

Aim: 
To assess the response of flatback hatchlings to common industrial light types a different intensities and elevation
Type of Study: 
Manipulative experiment
Key Results: 
At medium and high light intensities of all 3 light types (metal halide, fluorescent and high pressure sodium vapour) and at low intensity metal halide, hatchlings were more attracted to light at 2° elevation compared to 16° elevation. At low intensity there was no significant difference in orientation of hatchlings exposed to high pressure sodium or fluorescent light glow at either elevation.
Response: 
Maintain high inland elevations to improve hachling sea finding.
