How will the increase in salinity in water affect thermohaline circulation?
If there is an increase in salinity in water, then the thermohaline circulation will be slower compared to pure water; because fresh water is less dense than salt water, making it easier to diffuse.
The purpose of carrying out this experiment relates to the ocean water such as the Atlantic Ocean, Pacific Ocean, etc. How much salt the ocean contains determines how dense the ocean will be. In connection with the thermohaline circulation if the ocean contains more salt water, the denser the ocean will be as that will cause the less dense water to rise causing convection current. This will however reverse the thermohaline circulation. In result it may take a thousand of years to complete a full cycle of the thermohaline circulation.
Other people may find this interesting by when they discover how the salt water has an effect on the course at which the water travels. Ocean currents affect the weather patterns by when they are confined by land masses, making their heat transport move to specific regions.
Independent Variable: increase of salinity in water
Dependent Variable: thermohaline circulation
Predicted Relationship: direct or inverse other: ________
Other variables that need to be controlled: water
In my experiment I am comparing and contrasting the speed of the salinity in water versus regular top water. With this, it will show which one has a faster or slower speed. These will imitate the bodies of water.
My independent variable is measuring the increase of salinity in water.
My dependent variable is the thermohaline circulation and how the salt water will have an effect on this. Some of the conditions that may affect the thermohaline circulation would be measuring the distance wong when measuring speed, the temperature of the water, or the type of container I will be using for my experiment.
I assume that with more salt water the speed will be slow compared to regular water since the salt water will be dense. It will also sink to the bottom and that will push the tap water on top of it.
Regarding my experiment procedure, I believe that it will confirm my hypothesis. I will have two bottles: one with salt water with the lid connecting upside down to a bottle of tap water. With this I will do the reverse in several trials with water on top.
List of measurement tools and other equipment:
• 16 ounce clear bottle with equal opening size (4)
• Permanent marker
• Laminated index car (2)
• Table salt (150g)
• Containers for mixing and pouring solutions
• Stirring spoon or rod
• Teaspoon measuring spoon
• Food coloring (2 minimum)
• Hot and cold tap water
• Stop watch
1. Label one mixing container and one bottle “salt”. Repeat with another mixing container and bottle “water”
2. Add 1 teaspoon of salt and one cup of water to the salt container.
3. Add one cup of fresh tap water to the water container.
4. Add 5 drops of food coloring to each container. Make sure to use different colors so you can differentiate them when they are mixed together.
5. Add these mixtures to the corresponding bottles.
6. Invert one of the bottles on top of the other while keeping the laminated index card in between. It will not matter which is on top due to repeating this experiment twice more and three more times with the opposite bottle on top.
7. Remove the laminated card and observe the motion of the water.
8. Record observations and record speed (distance/time)
9. Repeat steps 1-7 but instead of using salt and fresh water, use cold and heated water.
10. After this has been done, try the experiment with hot salt water and fresh cold water with steps 1-8.
All of our trials that included salt vs. water and cold water vs. hot water had a change in intensity as time went by. With salt vs. water with water on top the increase was gradual. In contrast, the trials with salt on top was constant, increasing with a slope as time went by. There were also similar patterns on the trials that had cold vs. hot water. This supports our prediction of how when there is an increase in salinity in water, the thermohaline circulation will be slower compared to pure water. The salt color yellow slowly changed to green when mixed with water, blue. This showed that the speed of the salt water was slower compared to regular water due to the increase of salinity. This is the same with hot and cold water. Cold water being more dense and hot water being less dense.
