What factors affect the depth of the compensation zone?
Factors that affect the depth of the lysocline and the compensation depth include:
- Water temperature.
- CO 2 concentration.
- pH (high pH values aid in carbonate preservation)
- Amount of carbonate sediment supply.
- Amount of terrigenous sediment supply.
Where would the compensation depth be deeper?
Today, it is well established that the depth of the calcite compensation depth varies throughout the modern oceans, being in general deeper in the Atlantic than the Pacific.
What affects the carbonate compensation depth?
The exact value of the CCD depends on the solubility of calcium carbonate which is determined by temperature, pressure and the chemical composition of the water – in particular the amount of dissolved CO. 2 in the water. Calcium carbonate is more soluble at lower temperatures and at higher pressures.
What happens at the compensation depth?
The Compensation depth is a physiological concept: The depth at which the rate of photosynthesis for an individual plant equals the rate of respiration by that plant.
Why is the compensation depth important?
The position of the CCD is important to the global carbon cycle because it determines how much inorganic carbon is stored in deep ocean sediments. The amount of CO2 in the atmosphere also is interdependent with ocean productivity and the saturation state of seawater.
Why is it important to know compensation depth?
The marine environment
In well-mixed water columns plankton are evenly distributed, but a net production only occurs above the compensation depth. Below the compensation depth there is a net loss of organic matter. The total population of photosynthetic organisms cannot increase if the loss exceeds the net production.
Why is the CCD deeper in the Atlantic?
In the Atlantic basin the CCD is 500 metres (about 1,600 feet) deeper than in the Pacific basin, reflecting both a high rate of supply and low rate of dissolution in comparison to the Pacific.
Why is the CCD deeper in the Atlantic than Pacific?
The Pacific has a lower pH and is colder than the Atlantic, so its lysocline and CCD are higher in the water column because the solubility of calcite increases in these conditions.
What is compensation depth why is it significant to primary production in the ocean?
What is compensation depth? Why is it significant to primary production in the ocean? The point of zero net primary production. If Phytoplankton remain below the compensation depth for more than a few days, they will die.
How does increasing co2 in the ocean affect the calcium carbonate compensation depth?
High CO2levels make the water more acidic. The depth where all three of these effects show their might, where CaCO3 starts to dissolve rapidly, is called the lysocline. As you go down through this depth, seafloor mud starts to lose its CaCO3 content—it is less and less calcareous.
What would happen if the depth of the CCD were above the top of the mid ocean ridge?
What would happen if the depth of the CCD were above the top of the mid-ocean ridge? Calcareous ooze would not be found below the CCD.
What is compensation depth quizlet?
What is compensation depth? depth at which the light intensity is just sufficient to bring about a balance between the oxygen produced and that consumed by algae.
