Solubility of materials increases with decreasing temperature, the nutrients are consumed from shallower depths, and gravity tends to concentrate heavier materials deeper.

Upwelling
Ocean convection currents move the deep cold water to the surface of oceans.
An upwelling is a current in the ocean that brings deep, cold water to the ocean surface.

Deep ocean currents have enormous effect on climatic conditions. Deep ocean currents are also known as conveyor belt for temperature. There are two types of water currents, cold and warm. The warm water currents are less dense than cold water currents.
deep, cold water to the ocean surface
Rises to the surface.
because the water is to dark and cold
Thermal Layer
Upwelling is water raising from deep in the ocean to the surface. It can be caused by wind ar density currents.
