Why does water heat so slowly?
A small pot of water will heat quickly, while a large pot of water at the same heat setting will heat very slowly. This is due to a difference in heat capacity. The ocean has an enormous heat capacity because of its large size. So it is like an enormous pot of water, and it takes a great amount of heat to warm the ocean.
Why does the temperature of ocean water vary?
The temperature of ocean water varies by location – both in terms of latitude and depth, due to variations in solar radiation and the physical properties of water.

This results in less warming of the water. Therefore, the deep ocean (below about 200 meters depth) is cold, with an average temperature of only 4°C (39°F). Cold water is also more dense, and as a result heavier, than warm water. Colder water sinks below the warm water at the surface, which contributes to the coldness of the deep ocean. The vertical structure in the ocean created by temperature differences has a large impact on how life is distributed in the ocean.
Is the deep ocean cold?
Therefore, the deep ocean (below about 200 meters depth) is cold, with an average temperature of only 4°C (39°F). Cold water is also more dense, and as a result heavier, than warm water. Colder water sinks below the warm water at the surface, which contributes to the coldness of the deep ocean.
What is the difference between warm and cold water?
Cold, salty water is dense and sinks to the bottom of the ocean while warm water is less dense and remains on the surface.
Why does cold water get colder?
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 sinking and transport of cold, salty water at depth combined with the wind-driven flow of warm water at the surface creates a complex pattern ...
How much geothermal energy does the Earth produce?
Geothermal energy emanating from the Earth averages only about one tenth of a watt per square meter. At that rate of heat flow (without taking ocean currents into account), it would take well over a year just to heat the bottom meter of the ocean by one degree Centigrade.
Is the ocean still standing?
However, the ocean is not standing still. Complex deep ocean currents driven by density variations in temperature and salinity are constantly replacing the bottom layer of ocean water with colder water.
How does the temperature of the ocean vary?
The temperature of the ocean, especially the surface, varies from place to place and from season to season. Ocean temperature depends on the amount of solar energy absorbed.
What determines the form of water in the ocean?
The temperature of the ocean determines what form the water takes. Most of the ocean is liquid water, but if it gets cold enough, it turns to solid ice, or if it gets hot enough, it can pass into the atmosphere as water vapour
What instrument does Dr Phil Sutton use to measure the ocean?
Dr Phil Sutton of NIWA works on a CTD (Conductivity Temperature Depth) instrument package used to measure the ocean. CTD uses the same instruments as Argo scientific floats, but is lowered from ships. Salinity and temperature are measured at specific locations and depths, and are checked against Argo data.
Why is the ocean important to the Earth?
Water warms up more slowly than air but can hold more heat – water needs 4 times as much energy to raise its temperature by 1ºC as the same mass of air does – so the ocean plays an important part in taking up energy from the Sun and stopping the Earth getting too hot.
How many layers of the ocean are there?
The ocean has three main temperature layers. The upper (warm) and deep (cold) layers have the same temperature throughout. Between is the thermocline, which is warmer at the top than the bottom.
Why does water expand when it warms up?
Water expands when it warms up – heat energy makes its molecules move around more and take up more space. Because the molecules are more spread out, the density goes down. When water cools, it contracts and becomes denser.
What is the term for the layer of water that has a large variation in temperature from top to bottom?
Also called solar power. thermocline: A layer of water that has a large variation in temperature from top to bottom. In the ocean, it often separates surface waters from deep waters, both of which have similar temperatures throughout. gases: The state of matter distinguished from the solid and liquid states.
What is deep ocean water?
Jump to navigation Jump to search. Cold, salty water deep below the surface of Earth's oceans. Deep ocean water (DOW) is the name for cold, salty water found deep below the surface of Earth's oceans. Ocean water differs in temperature and salinity.
How does ocean water differ from surface water?
Ocean water differs in temperature and salinity. Warm surface water is generally saltier than the cooler deep or polar waters; in polar regions, the upper layers of ocean water are cold and fresh.

What happens when cold water passes through a pipe surrounded by humid air?
When cold water passes through a pipe surrounded by humid air, condensation results. The condensate is pure water, suitable for humans to drink or for crop irrigation. Via a technology called Ocean thermal energy conversion, the temperature difference can be turned into electricity.
Why does water not reach ambient temperature?
During condensation or Ocean thermal energy conservation operations, the water does not reach ambient temperature, because a certain temperature gradient is required to make these processes viable. The water leaving those operations is therefore still colder than the surroundings, and a further benefit can be extracted by passing this water through underground pipes, thereby cooling agricultural soil. This reduces evaporation, and even causes water to condense from the atmosphere. This allows agricultural production where crops would normally not be able to grow. This technique is sometimes referred to as "cold agriculture" or "cold-bed agriculture".
What is the most useful property of water?
Its most useful property is its temperature. At the surface of the Earth, most water and air is well above 3 °C. The difference in temperature is indicative of a difference in energy. Where there is an energy gradient, skillful application of engineering can harness that energy for productive use by humans. The simplest use of cold water is ...
What is the use of cold water?
The simplest use of cold water is for air conditioning: using the cold water itself to cool air saves the energy that would be used by the compressors for traditional refrigeration. Another use could be to replace expensive desalination plants.
What is DOW in water?
DOW is typically used to describe ocean water at sub-thermal depths sufficient to provide a measurable difference in water temperature. When deep ocean water is brought to the surface, it can be used for a variety of things. Its most useful property is its temperature.
Why Is The Ocean Colder Than The Land?
In physics, there is a concept known as specific heat capacity, which refers to the amount of energy required to increase the temperature of a kilogram of a substance by one degree. Each kind of substance has a different specific heat capacity.
Ocean Currents Affect The Overall Water Temperature
Ocean currents are the movement of streams of water within the ocean. They occur for various reasons, but the pertinent point of our discussion is where these currents arise.
Why Do Different Oceans Have Different Temperatures?
It is easy to see the effects of currents by comparing the oceans’ temperature on either side of a continent. This is clearly seen in southern Africa, where the Benguela current on the west makes the Atlantic Ocean much colder. The Indian Ocean on Africa’s east coast is warmed by the Agulhas current that originates at the equator.
Does The Wind Make The Oceans Cold?
The wind plays an influential role in the temperature of the oceans. The energy from the sun heats the water surface, and the top layers of the water vaporize (or evaporate). The warm water vapor and air molecules move upwards, and cold air sinks in to replace the warm air. In this way, the water loses heat to evaporation.
Why Is The Ocean So Cold When You Scuba Dive?
The deeper water in the ocean is always colder because it receives less solar radiation. The sunlight and heat energy can only penetrate the top layers of the sea.
How Does Latitude Affect Ocean Temperature?
Tropical oceans near the equator receive many hours of sunlight each day, allowing them to warm up considerably. Oceans near the polar regions receive very few hours of sunlight throughout the year, and the water is freezing as a result.
Perceptions Make The Water Feel Colder
When our skin is warm and we encounter the water from the ocean, our nervous system notes the contrast. We generally perceive the water to be colder than it is because of the temperature difference.

What causes the ocean to be cold?
The ocean is characterized by upwelling caused by westerly winds blowing around the continent. The upwelling brings up waters from the ocean’s depths which is usually cold. Waters in the Southern Ocean are different from those in the oceans bordering it and are uniform throughout the confines of the ocean’s boundary.
How deep is the ocean?
The ocean is 23,740 feet at its deepest, but its depth averages between 13,000 and 15,000 feet. The Southern Ocean is significantly warmer than the continent, with water temperatures ranging between -2 °C and 10 °C. During winter, most of the Southern Ocean freezes solid, all the way up to the 65-degree South latitude.
What is the northernmost boundary of the ocean?
The northernmost border of the ocean is marked by the extent of the 13,000-mile long Antarctic Circumpolar Current. As the currents collide against the Antarctic Continental Shelf, it forms two gyres; the Weddell Gyre and the Ross Gyre. The waters in these gyres are cold as they are drawn from the depths of the ocean.
What is the ice sheet that flows towards the sea?
The ice sheet flows towards the sea where warmer temperatures cause it to crumble into icebergs. These icebergs that float over the surrounding ocean vary in size, with some being bigger than islands. Iceberg B-15 is unusually large, bigger than the entire island of Jamaica.
What are the two main factors that influence the temperature of the ocean?
Temperatures around the ocean are influenced by winds and currents that encircle the ocean. Some of these winds and currents include the Polar Front, the Antarctic Convergence, and the Antarctic Circumpolar Current.
What is the coldest place on Earth?
The temperatures of the Antarctica's Southern Ocean are influenced by winds and currents that encircle the ocean. Continental Antarctica is the coldest place on earth, with temperatures in some parts being lower than those experienced on Mars. Surface temperatures average at -10 °C but can plunge to -68 °C further inland.
Why are the gyres cold?
The waters in these gyres are cold as they are drawn from the depths of the ocean. Also encircling the continent is the Antarctic Convergence, where the warm subantarctic waters merge with the cold waters of the Antarctic, resulting in vast amounts of nutrients and consequentially of phytoplankton.
