Scientists use underwater robot to spy on zooplankton at night
January 10, 2018 by Allie Nicodemo, Northeastern University
Zooplankton are the foundation of the marine food chain. These tiny organisms provide food and energy to fish, sea birds, and other marine mammals—including the bowhead whale, which feeds exclusively on zooplankton. What do zooplankton eat? They feed on phytoplankton, which rely on sunlight.
But in the Arctic Ocean during winter months, there is little to no light. Still, scientists have observed that zooplankton migrate from the deep ocean up to the surface. But this phenomenon is difficult to study. Most research vessels produce light pollution, or artificial light, which alters the zooplanktons' natural behavior.
