Frequent question: What is the significance of the carbonate compensation depth?

What is the significance of the carbonate compensation depth CCD )? How might ocean acidification affect the CCD?

What is the significance of the carbonate compensation depth (CCD)? how might ocean acidification affect the CCD? The depth provided by the CCD gives us the threshold in which calcium carbonate is dissolved. Acidification could cause the CCD to rise and slower coral reef growth and production of calcium carbonate.

What is the carbonate compensation depth what factors affect it?

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 is the carbonate compensation depth CCD and why don’t calcareous oozes form beyond them?

Carbonate Compensation Depth, abbreviated as CCD, refers to the specific depth of the ocean at which calcium carbonate minerals dissolve in the water quicker than they can accumulate. … This creates a calcareous ooze that can, under pressure from the overlying water, form limestone or chalk.

What is the carbonate compensation depth quizlet?

What is the Carbonate Compensation Depth (CCD)? Calcium Carbonate Compensation Depth (CCD) the depth at which the rate of accumulation of calcareous sediments equals the rate of dissolution. Be able to describe why calcareous oozes (CaCO3) are not found in the deep ocean bottom.

Why is compensation depth significant to primary productivity 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.

Why is the CCD deeper in the Atlantic?

Because the supply and dissolution rates of carbonate differ from place to place, the depth of the CCD is variable. In the Indian Ocean and the Pacific, the CCD is typically found at depths between 3,500 and 4,500 m. In the North Atlantic and the eastern South Atlantic, the CCD occurs deeper than 5,000 m.

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 the difference between critical depth and compensation depth?

In Sverdrup’s words, the compensation depth is defined as the depth at which the energy intensity is such that the production by photosynthesis balances destruction by respiration. The critical depth is the depth above which daily integrated net production is zero.

What is the calcium carbonate compensation depth is there a compensation depth for the siliceous components of once living things?

Is there a compensation depth for the siliceous components of once living things? The depth in the oceans below which the rate of supply of calcite lags behind the rate of solution, such that no calcite is preserved.

How is the carbonate compensation depth CCD related to the worldwide distribution of calcareous oozes?

The carbonate compensation depth (CCD) is the dominant facies boundary on the deep-sea floor. It separates calcareous from noncalcareous sediments, with the calcareous deposits (“carbonate ooze”) restricted roughly to the shallower half of the deep-sea floor.

Why do siliceous deposits dominate sediments below the carbonate compensation depth?

Why do siliceous deposits dominate sediments below the calcium carbonate compensation depth? Due to the slow deep-sea dissolution of siliceous remains and high diatom productivity. … They are a source of calcium carbonate, calcium sulfate, gypsum andsodium chloride.

Why is the CCD shallower in the Pacific?

The CCD gets shallower as deep waters migrate from the Atlantic through the Indian to the Pacific ocean. CaCO3 deposition/preservation on the sea floor. … This occurs without much increase in CaCO3 flux, resulting in a shallower CCD than we’d otherwise predict.
