Since AR5, increasing spatio-temporal extent of hypoxia has been projected due to enhanced benthic respiration and reduced oxygen solubility from warming . Similar to the open ocean, large shifts in the phenology of phytoplankton blooms have been projected for shelf seas throughout subpolar and polar waters  . Zooplankton, which are important prey for many fish species and sea birds, are expected to decrease in abundance on the northeast shelf of the USA ; however, responses vary by shelf ecosystem . Trends towards tropicalisation will continue in the future  , but uncertainty of future projections of fisheries production increases substantially beyond 2040 . Nevertheless, shelf- sea fisheries at lower latitudes are most vulnerable to climate change . Under future climate change marked by more frequent and intense extreme events and the influences of multiple drivers, more flexible and adaptive management approaches could reduce climate impacts on species while also supporting industry adaptation  .
