Background information and definitions
Artificial lighting at night, including urban lighting from street lights and houses, industrial lighting from shops and offices, and underwater lighting in marinas and on pontoons, has recently been recognized as a cause for marine environmental concern (Davies et al. 2014). Light pollution has been shown to negatively affect the behaviour of several species, and the community composition of marine invertebrates (Davies et al. 2015; Navarro-Barranco & Hughes 2015). Limiting (in duration, intensity or spectral composition), ceasing or prohibiting lighting at night in an area may reduce the levels of light pollution affecting subtidal benthic invertebrates (Gaston et al. 2012).
