Topic 1.3 - Density and Pressure in the Ocean Layers

Episode 2: Density and Ocean Layershttps://oceanambassadors.org/Master the role of density in the marine environment. In this bite-sized revision lesson, you'll learn how temperature, pressure, and salinity affect the density of seawater, and apply the density formula to solve exam-style questions. We'll also explain why ice floats, why this is essential for marine life, and how differences in temperature and salinity create distinct ocean layers, including the surface layer, thermocline, halocline, and deep ocean. By the end of this episode, you'll have a solid understanding of these key syllabus concepts and be better prepared for Cambridge AICE Marine Science exam questions.
