Research Shows How Artificial Light Affects Arctic Fish Counts

Facebook X LinkedIn Email
University of Delaware College of Earth, Ocean, and Environment professor Jonathan Cohen has co-written a new study that looks at how artificial light during the polar night disrupts Arctic fish and zooplankton behavior at depths to 200 m. According to the finding, published in Communications Biology, the disruption of species behavior so far down in the water column could introduce biases on stock assessments of commercial and noncommercial fish species. “You’re trying to measure and understand the position of animals in the water column, a process that's very light...Read full article

    light field
    The term light field refers to the spatial distribution of light rays traveling in all directions through a given space. It includes information about the intensity and direction of light rays at every point in a scene. In the context of imaging and photography, the light field is a comprehensive description of the light entering a camera or other optical system. Key points about light field include: Directional information: Unlike traditional photographs that capture only the total light...
