標題：AZFP論文：人為光源對北極極夜200米深處的北極魚類和浮游動物的擾亂
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.

對在地球上最后一個不受干擾和原始的黑暗環(huán)境之一---北極極夜中仍然活躍的生物來說，月球、恒星和北極光可能為指導分布和行為提供重要線索，包括捕食者與獵物的相互作用。隨著北極氣候的變化和人類活動的增加，在許多地方，這種自然光源將被人造光更強的照明所掩蓋。在這里，我們表明，來自船只的正常工作光可能會在船只周圍>0.125平方公里的區(qū)域內(nèi)，擾亂魚類和浮游動物在至少200米深處的行為。受檢區(qū)域之間干擾的定量和定性性質(zhì)都不同。我們得出結論，在黑暗中從有照明的船只進行生物調(diào)查可能會對生物采樣、生物聲學調(diào)查以及可能對商業(yè)和非商業(yè)物種的種群評估產(chǎn)生偏見。
