Artificial Light and Fish Counts

Caption

UD Prof. Jonathan Cohen is a co-author of a new study looking at how artificial light during the polar night disrupts Arctic fish and zooplankton behavior down to 200 meters in depth, which could affect fish counts. Cohen said that research vessels during the Arctic polar night are like Christmas trees illuminated in the middle of the dark ocean.
