Introduction to Indicator

Zooplankton represent a critical trophic link from primary producers to fish in marine ecosystems.

Key Results and Visualizations

Abundance anomalies of small and large copepods have varied over time by EPU. Small bodied copepods and cnidarians show increasing trends in all EPUs. Large bodied copepods and euphausiids show no significant trend in any EPU.

Implications

Check these. If they are correct, we could be seeing the less energy dense zooplankton becoming more abundant in each system.
