The Sunlight Zone - 0 to 200 meters
The epipelagic zone, also known as the sunlight zone, is the uppermost layer of the ocean. Extending from the surface to a depth of around 200 meters, this zone receives ample sunlight, making it the most biologically active layer in the ocean.
Key Features
- Depth: 0 - 200 meters
- Light: Abundant sunlight
- Temperature: Warmest among ocean layers
- Pressure: Relatively low compared to deeper zones
- Oxygen: High — supports rich marine life
Why It Matters
- Photosynthesis occurs here due to sunlight, producing over 50% of Earth's oxygen.
- It's the starting point of the marine food chain.
- It supports fisheries and coastal ecosystems.
