Overview

Time-series analysis shows cyclical climate fluctuations drive ecosystem productivity across marine trophic levels, highlighting the necessity of climate-informed fisheries management.

Key Points

  • To identify how ocean climate fluctuations correspond with multi-trophic ecosystem productivity to better inform sustainable fisheries management under climate change.
  • Analyzed over 70 years of historical climate and fisheries data from the Newfoundland and Labrador continental shelves.
  • Assessed productivity patterns across multiple trophic levels, ranging from primary producers to piscivorous fish, alongside regional ocean climate and Northern Hemisphere atmospheric indicators.
  • Cyclical shifts in ecosystem productivity strongly coincide with regional ocean climate changes and broad Northern Hemisphere atmospheric configurations.
  • Climate-driven productivity trends demonstrate broad multi-trophic correspondence across both lower and higher trophic levels.
