What does the thermocline separate?

The thermocline separates the surface from the deep ocean. Due to density differences, the surface and deep ocean layers do not easily mix. This means that the gases dissolved in surface seawater, such as CO2, also get mixed into deep seawater on longer timescales.

What is the thermocline in the ocean?

A thermocline is the transition layer between warmer mixed water at the ocean’s surface and cooler deep water below. Below 3,300 feet to a depth of about 13,100 feet , water temperature remains constant.

What is a thermocline quizlet?

A thermocline (sometimes metalimnion in lakes) is a thin but distinct layer in a large body of fluid (e.g. water, such as an ocean or lake, or air, such as an atmosphere) in which temperature changes more rapidly with depth than it does in the layers above or below. You just studied 10 terms!

How do you identify a thermocline?

The depth where the oxygen line takes a left toward the zero side of the graph is the top of the thermocline. “You can also go out in the middle of the lake and turn up the sensitivity on your sonar unit until you see a band in the depths,” Dreves said. “That band is the thermocline.

What is a thermocline how does it affect sea surface temperatures?

Thermocline, oceanic water layer in which water temperature decreases rapidly with increasing depth. A widespread permanent thermocline exists beneath the relatively warm, well-mixed surface layer, from depths of about 200 m (660 feet) to about 1,000 m (3,000 feet), in which interval temperatures diminish steadily.

What causes a thermocline?

Thermoclines are caused by an effect called stratification in lakes. The warm layer of water which is heated by the sun sits on top of the cooler, denser water at the bottom of the lake and they are separated by a thermocline. Thermocline depth in lakes varies depending on the heat of the sun and the depth of the lake.

What does the thermocline do?

A thermocline refers to a boundary of water which separates regions of warmer water from the colder water below. A Thermocline is formed by the effect of the sun, which heats the surface of the water and keeps the upper parts of the ocean or water in a lake, warm.

What is the average temperature of deep water below the thermocline?

32-37.5 degrees Fahrenheit

Can fish live below the thermocline?

The thermocline is a layer of water towards the bottom that has no oxygen or very little oxygen. Fish can venture below the thermocline to feed but they can’t stay there for extended periods of time.

Why does water temperature decrease with depth?

Water gets colder with depth because cold, salty ocean water sinks to the bottom of the ocean basins below the less dense warmer water near the surface. The actual amount of heat generated per square meter of Earth is quite small, especially compared to the amount of heat necessary to warm the ocean.
