Ocean Layers & Impact of Dead Zones

Ocean Layers Overview

  • Importance of Dead Zones

    • Dead zones are dangerous for organisms in deeper ocean zones due to low oxygen availability, which impacts their survival and metabolism.

  • Main Ocean Layers (Shallowest to Deepest)

    1. Epipelagic Zone (Surface Layer)

    2. Mesopelagic Zone (Twilight Zone)

    3. Bathypelagic Zone (Midnight Zone)

    4. Abyssopelagic Zone (Abyss Zone)

    5. Hadalpelagic Zone (Hadal Zone)

  • Photosynthesis

    • Occurs primarily in the Epipelagic Zone due to sufficient sunlight penetration.

  • Coral Reefs

    • Coral reefs are limited to the Epipelagic Zone because they require sunlight for photosynthesis and thrive in shallow waters.
