dc.description.abstractBioluminescence commonly influences pelagic trophic interactions at mesopelagic depths. Here we characterize a vertical gradient in structure of a generally low species diversity bioluminescent community at shallower epipelagic depths during the polar night period in a high Arctic fjord with in situ bathyphotometric sampling. Bioluminescence potential of the community increased with depth to a peak at 80 m. Community composition changed over this range, with an ecotone at 20–40 m where a dinoflagellate-dominated community transitioned to dominance by the copepod Metridia longa. Coincident at this depth was bioluminescence exceeding atmospheric light in the ambient pelagic photon budget, which we term the bioluminescence compensation depth. Collectively, we show a winter bioluminescent community in the high Arctic with vertical structure linked to attenuation of atmospheric light, which has the potential to influence pelagic ecology during the light-limited polar night.en_US
dc.description.sponsorshipThe study is a partial contribution to the five Norwegian Research Council-funded projects ABC (NRC project number 244319), Marine Night (NRC project number 226417), Sensitivity (NRC project number 240721), EWMA (NRC number 195160), and AMOS CoE (NRC project number 223254). Sampling was also carried out as an integrated part of the University Centre of Svalbard’s Underwater Robotics and Polar Night Biology course AB334/834 in 2014. Additional support was provided by the University of Delaware.en_US
