Oxygen in ocean water mainly comes from two sources: photosynthesis by marine plants and phytoplankton, and diffusion from the atmosphere at the water's surface. Photosynthesis by marine plants produces oxygen as a byproduct, while surface diffusion replenishes oxygen levels that can be consumed by marine organisms.

Does Ocean water has higher levels of oxygen than air?

No, ocean water does not have higher levels of oxygen than air. The concentration of oxygen in ocean water is much lower compared to the amount found in the atmosphere. Ocean water contains dissolved oxygen essential for marine life, but the overall oxygen content is lower than that of the air.


Is there oxygen on the ocean floor?

There is no free oxygen on the ocean floor. Oxygen is usually present in the water column, but it becomes depleted in deeper parts of the ocean where organic matter decays and consumes the available oxygen.


HOW do temperature of ocean water affect oxygen levels in water?

As the temperature of ocean water increases, the solubility of oxygen in water decreases. Warmer water holds less dissolved oxygen than cooler water. This can lead to lower oxygen levels in the water, which can negatively impact marine life that rely on oxygen for survival.

Where does the water from the ocean come from?

The water in the ocean comes from various sources, including rivers, precipitation, and groundwater seepage. The water cycle plays a critical role in replenishing the ocean with freshwater from these sources. Evaporation from the ocean's surface is also a major contributor to the water cycle that sustains the water in the ocean.

What is the percentage of oxygen in the ocean water?

The average percentage of dissolved oxygen in ocean water is typically around 3-6%, but this can vary depending on factors such as temperature, salinity, and depth of the water.
