Gases of the Ocean WaterGases of the Ocean Water

Elements in the ocean Elements in the ocean waterwater- 96.5% pure water - 96.5% pure water (3.5% salt only)(3.5% salt only)

Most abundant elementsMost abundant elements- Chlorine- Chlorine- Sodium- Sodium- Magnesium- Magnesium- Sulfur- Sulfur- Calcium- Calcium- Potassium- Potassium

The most dissolved The most dissolved gases which are the gases which are the three principle gases three principle gases are:are:- Nitrogen- Nitrogen- Oxygen - Oxygen - Carbon Dioxide- Carbon Dioxide

Some examples of where Some examples of where gases come from in gases come from in the ocean water are the ocean water are volcanoes and plants volcanoes and plants beneath the ocean.beneath the ocean.

Salinity of the Ocean Salinity of the Ocean WaterWater

Salinity is the number of grams of Salinity is the number of grams of dissolved salt in 1 kg of ocean water.dissolved salt in 1 kg of ocean water.

The dissolved gases depend on the The dissolved gases depend on the salinity. salinity.

Both evaporation and freezing Both evaporation and freezing increase the salinity of the ocean increase the salinity of the ocean water.water.

Also, if the rate of evaporation is high, Also, if the rate of evaporation is high, the salinity of surface water increases. the salinity of surface water increases.

Temperature of the Ocean Temperature of the Ocean WaterWater

Ocean has the ability to Ocean has the ability to obtain invisible infrared obtain invisible infrared wavelengths of sunlight.wavelengths of sunlight.

The absorption of these The absorption of these infrared ray heats the infrared ray heats the water.water.

Infrared rays means that Infrared rays means that completely absorbed completely absorbed within the upper zone of within the upper zone of the ocean water.the ocean water.

This means that the sun This means that the sun can directly heat water can directly heat water near the surface of the near the surface of the oceanocean

Deep zone-temperature Deep zone-temperature equals 2 degrees Celsius.equals 2 degrees Celsius.

Density of the Ocean Density of the Ocean WaterWater

Density mass underwater of an object Density mass underwater of an object can be divided by its volume.can be divided by its volume.

Density is measured in different ways but Density is measured in different ways but mostly in grams per cubic centimeters. mostly in grams per cubic centimeters.

Oceanographers use the formula D=M/V Oceanographers use the formula D=M/V to calculate the density in the water.to calculate the density in the water.

In conclusion you just need to measure In conclusion you just need to measure the salinity, temperature and pressure to the salinity, temperature and pressure to be able to find densitybe able to find density and using the and using the formula.formula.


If the object is denser than the water it will If the object is denser than the water it will not sink, and if it is it will sink.not sink, and if it is it will sink.

The salt in the ocean water makes the water The salt in the ocean water makes the water denser.denser.

As the temperature decreases it gets more As the temperature decreases it gets more denser. So, the colder the water, the more denser. So, the colder the water, the more dense it is.dense it is.

The dense difference divide them so that the The dense difference divide them so that the more denser water is on the bottom of the more denser water is on the bottom of the less dense.less dense.

The temperature of the ocean greatly The temperature of the ocean greatly decreases as you go more to the bottom of decreases as you go more to the bottom of the ocean. So, the density of the water goes the ocean. So, the density of the water goes up as you go down into the bottom of the up as you go down into the bottom of the ocean.ocean.


Color of the Ocean Color of the Ocean WaterWater

The color of the ocean water is The color of the ocean water is determined by the way it absorbs or determined by the way it absorbs or reflects sunlight. reflects sunlight.

The ocean is blue because blue is the The ocean is blue because blue is the last color to be absorbed and it reflects last color to be absorbed and it reflects the sunlight.the sunlight.

The ocean covers about 70% of the The ocean covers about 70% of the earth’s surface. earth’s surface.


Most of the sunlight that penetrates the Most of the sunlight that penetrates the surface of the ocean is absorbed by the water. surface of the ocean is absorbed by the water.

Also, the water appears blue because blue is Also, the water appears blue because blue is the last color to be absorbed; but sometimes the last color to be absorbed; but sometimes the ocean is covered by small particles and the ocean is covered by small particles and marine organisms floating in the water, which marine organisms floating in the water, which causes the water to appear green or brown.causes the water to appear green or brown.

The sunlight can only go so far, it only covers The sunlight can only go so far, it only covers about a few hundred meters in depth, the about a few hundred meters in depth, the remaining is total darkness.remaining is total darkness.
