标题：AZFP论文：人为光源对北极极夜200米深处的北极鱼类和浮游动物的扰乱
Abstract
For organisms that remain active in one of the last undisturbed and pristine dark environments on the planet—the Arctic Polar Night—the moon, stars and aurora borealis may provide important cues to guide distribution and behaviours, including predator-prey interactions. With a changing climate and increased human activities in the Arctic, such natural light sources will in many places be masked by the much stronger illumination from artificial light. Here we show that normal working-light from a ship may disrupt fish and zooplankton behaviour down to at least 200 m depth across an area of >0.125 km2 around the ship. Both the quantitative and qualitative nature of the disturbance differed between the examined regions. We conclude that biological surveys in the dark from illuminated ships may introduce biases on biological sampling, bioacoustic surveys, and possibly stock assessments of commercial and non-commercial species.

For organisms still active in one of the last undisturbed and primitive dark environments on Earth - the Arctic polar night - the Moon, stars, and Northern Lights may provide important clues to guide distribution and behavior, including predator-prey interactions. With the change of Arctic climate and the increase of human activities, in many places, this natural light source will be overshadowed by stronger artificial lighting. Here, we indicate that normal working light from ships may disrupt the behavior of fish and planktonic animals at a depth of at least 200 meters within an area of>0.125 square kilometers around the ship. The quantitative and qualitative properties of interference between the tested areas are different. We conclude that conducting biological surveys from illuminated vessels in the dark may bias biological sampling, bioacoustic surveys, and population assessments of commercial and non-commercial species.

对在地球上最后一个不受干扰和原始的黑暗环境之一---北极极夜中仍然活跃的生物来说，月球、恒星和北极光可能为指导分布和行为提供重要线索，包括捕食者与猎物的相互作用。随着北极气候的变化和人类活动的增加，在许多地方，这种自然光源将被人造光更强的照明所掩盖。在这里，我们表明，来自船只的正常工作光可能会在船只周围>0.125平方公里的区域内，扰乱鱼类和浮游动物在至少200米深处的行为。受检区域之间干扰的定量和定性性质都不同。我们得出结论，在黑暗中从有照明的船只进行生物调查可能会对生物采样、生物声学调查以及可能对商业和非商业物种的种群评估产生偏见。
