Werewolves have become known as the pets of the polar night researchers. Both in the CircA and in the Marine Night project much attention was paid to their behaviour and how the lunar cycle affects their behaviour. A newly published paper under the lead of Kim S. Last in Current Biology sheds some (moon-)light on these mysteries. The paper is accompanied by a “behind the scenes” video produced by SAMS. You can download the paper “Moonlight Drives Ocean-Scale Mass Vertical Migration of Zooplankton during the Arctic Winter” (Current Biology 26, 1-8, 2016) here (open access) and watch the video below or in Youtube here. The paper had a massive media impact, include mentions in the New York Times and New Scientist. A comprehensive list of all media coverage can be found in the CircA publications and outreach section.
