Ocean Currents

How these connect

Coastal and Equatorial Upwelling and what it relates to. Every line is an evidence-backed relation, and the arrangement is fixed — this address draws this picture, today and next year.

Every relation drawn, in words6
  1. Peruvian Anchoveta (Engraulis ringens) · depends_on · Coastal and Equatorial Upwelling

    Anchoveta biomass tracks the nutrient supply that upwelling brings to the sunlit layer off Peru.

  2. El Niño–Southern Oscillation (ENSO) · affects · Peruvian Anchoveta (Engraulis ringens)

    Strong El Niño events collapse the anchoveta stock within months by removing the nutrient supply beneath it.

  3. El Niño–Southern Oscillation (ENSO) · affects · Coastal and Equatorial Upwelling

    A deepened eastern Pacific thermocline during El Niño means the same wind pulls up warm, nutrient-poor water instead of cold, nutrient-rich water.

  4. Humboldt (Peru–Chile) Current · instance_of · Coastal and Equatorial Upwelling

    The Peru–Chile flow is one of the four eastern boundary upwelling systems and the most productive of them.

  5. Coastal and Equatorial Upwelling · depends_on · Ekman Transport and the Ekman Spiral

    Coastal upwelling occurs where alongshore wind drives Ekman transport offshore and deeper water rises to replace it.

  6. Coastal and Equatorial Upwelling · part_of · Thermohaline Circulation

    Upwelling is the return half of the circuit: sinking is concentrated in a few places, rising is spread over much of the ocean, and the asymmetry is the interesting part.
