oceanographic pressure zones

Oceanographic pressure zones are layers within the ocean where water pressure varies mainly due to depth. As you go deeper, pressure increases because of the weight of the overlying water. The ocean is divided into the surface zone (less pressure), the thermocline (where temperature and pressure change rapidly), and the deep zone (high pressure, near freezing temperatures). These zones influence marine life, ocean currents, and how sound travels underwater. Understanding these pressure zones helps scientists study ocean dynamics, marine ecosystems, and submarine geology more accurately.
