What is species diversity?

The variety and abundance of different species within a specific geographical area or ecosystem.

When does thermal stratification occur?

1. Sunlight heats the upper layer of water and surface movements create a layer with a fairly consistent temperature.

2. Water movement below the surface mixed layer is reduced due to the calm weather and the sun continues to warm the water. Sunlight penetration declines with depth resulting in a temperature variation from the top to the bottom of the thermocline.
