Short summary
Diel vertical migration (DVM) of zooplankton is the largest nonhuman migration on the Earth. DVM in the eastern Beaufort Sea was assessed using a 2-year-long time series of currents and acoustic signal from a bottom-anchored oceanographic mooring. Our results show that DVM is deviated by the (i) seasonal and interannual variability in sea ice and (ii) wind-driven water dynamics. We also observed the midnight-sun DVM during summer 2004, a signal masked by suspended particles in summer 2005.
