the first layer is the surface layer it is nice and warm and mixed with the waves.
the next layer is the thermocline it is just warm not any thing special.
the next is freezing cold i would not want to go there.
Surface zone
A basic answer is that the densest ocean water is the saltiest - a ship floats higher in salt water (sea) than in fresh water (lake). Also cold water tends to sink towards the ocean floor, or may form a layer mid way.
The density of surface seawater ranges from about 1.020 to 1.029 g·cm-3, depending on the temperature and salinityThe average density of seawater at the surface of the ocean is 1.025 g/ml; seawater is denser than freshwater (which reaches a maximum density of 1.000 g/ml at a temperature of 4°C) because of the added mass of the salts.

Thermocline
The coldest place in the Ocean is in the deep water layer. The water temperature in this zone decreases slowly as depth increases.
because the ocean is made of salt water and the most salt wateris at the top
The temperature of ocean water can be affected by the depth. The deeper it gets, the colder the temperature. The current also can affect the temperature of ocean water.
because the winds blowing in from the ocean pick up the temperature from the water so the wind is the same temperature as the top layer of the water, so when the wind blows in from the coast it either warms or cools the land depending on the water temperature.
temperature,salinity,and density
Pressre increases as you move from the surface to the ocean floor. The pressure is a result of the weight of the water above. The deeper you go, the more water you will have above you and the greater the weight and thus pressure.In general temperatures decrease as you move from the surface to the ocean floor. The simplest reasons for this are:the energy of the sun does not penetrate deep into the ocean so the lower layers cannot be warmed by itcolder water is more dense and sinks while warmer water risesThis is only a general rule however. Near thermal vents, the temperatures can be above the boiling point of water - even at the high pressures found at the bottom of the ocean.The decrease in temperature is not a smooth one. Much of the ocean has a layered temperature structure. The sun-warmed surface water mixes with cooler, deeper waters as winds, breaking waves and turbulent currents stir the water. One result of this mixing is a surface layer having nearly uniform temperature, or isothermal, conditions. The temperature of seawater immediately below the mixed layer changes rapidly with depth. This layer of rapid temperature change extends down to about 1,000 m and is called the main thermocline. The main thermocline separates the warmer mixed layer above from the cooler deep layer below. In the deep layer, the water is almost isothermal, with only a gradual decrease in temperature to the ocean floor. The deep layer starts at a depth of around 1,000 m and extends to the ocean floor.
This is known as a thermocline. It is a layer where the temperature decreases rapidly with depth. The thermocline often separates the warm surface waters from the colder deeper waters in a lake or ocean.
