Migrating Zooplankton

Diel Vertical Migration (DVM) of zooplankton has been widely recognized as an important factor contributing to the carbon sink. DVM is driven by the predatory pressure on zooplankton during daylight, leading to migration depths ranging between 200m and 800m. The amount of active transport compared to passive gravitational flux is estimated to be between 15% and 40% at present. DVM is not included into OGCBMs due to its complexity, variability and poor characterization, in line with other processes in the twilight zone. This poster was presented at the Ocean Sciences Conference 2016 in New Orleans, US.
