what are the characteristics of the mixed zone of the ocean?
429399
The oceanic or limnological mixed layer is a layer in which active turbulence has homogenized some range of depths. The surface mixed layer is a layer where this turbulence is generated by winds, surface heat fluxes, or processes such as evaporation or sea ice formation which result in an increase in salinity.

The amount of oxygen in seawater has dropped in many parts of the global ocean, leading to the expansion of what are known as “oxygen minimum zones.” This is partly because warmer water holds less oxygen, but the main reason is that warming makes ocean layers less inclined to mix, meaning less oxygen is transported ...

Using the map of sea surface temperature, you might have noticed that the eastern boundary currents (on east sides of oceans) carry cold water from the polar (or sub-polar) region towards the equator, whereas the western boundary currents carry warm water from the equator towards the polar regions.

The ocean has three main zones, where many different animals live. The zone that gets the most sunlight and where the ocean plants and most ocean animals live is called the sunlit zone. Below the sunlit zone is the twilight zone, which gets very little sunlight.

Average temperature of the ocean surface waters is about 17⁰ Celsius, or 62.6⁰ Fahrenheit.

Ocean waters are salty and contain minerals and dissolved gases. They also have a high heat capacity and vary in density depending on temperature and salinity.

The speed of all ocean waves is controlled by gravity, wavelength, and water depth. Most characteristics of ocean waves depend on the relationship between their wavelength and water depth. Wavelength determines the size of the orbits of water molecules within a wave, but water depth determines the shape of the orbits.

Surface water temperatures in the Pacific can vary from −1.4 °C (29.5 °F), the freezing point of sea water, in the poleward areas to about 30 °C (86 °F) near the equator. Salinity also varies latitudinally, reaching a maximum of 37 parts per thousand in the southeastern area.

Abiotic factors are non-living factors within an ecosystem. These include things like temperature, rainfall, soil quality, and altitude. So, in the pelagic zone of the ocean, some biotic factors might be: Marine life (fish, sharks, etc.)
