PPT-Ocean Life Zones Ocean life is determined by many factors:

A Sunlight Producers require sunlight for photosynthesis Ocean life is determined by many factors B Temperature most animals live near the surface where it is warmer Ocean life is determined by many factors.

It's within this steady environment that the rich and varied web of life in today's seas has arisen and flourished. But research shows that this ancient balance is being undone by a recent and rapid drop in surface pH that could have devastating global consequences..

Salinit. y. - measure of the mount of dissolved salts and other solids in a given liquid. Thermocline. - marks the distinct separation between the warm surface water and the deep, cold water. Summary. This lesson explains the life cycle of sea turtles focusing on specific aspects of the loggerhead sea turtle life cycle. The Southeastern U.S. has the largest nesting aggregation of loggerhead sea turtles. Sea turtles are also charismatic .
