•Sediment traps were deployed at three sites in the Beaufort Sea.•The early onset of snowmelt led to an early release of ice algae in 2016.•The early melt led to the highest diatom and phytoplankton carbon fluxes in 2016.•Annual phytoplankton carbon fluxes ranged from 13 to 520 mg C m−2 yr−1 in 2016...
