niveau de compensation des carbonates  

DEFINICIÓN

  • Kalsiyum karbonat çözünme hızının kalsiyum karbonat birikim hızına eşit veya daha fazla olduğu, bu nedenle daha aşağıda biriken çökellerin yok denecek kadar az oranda CaCO3 içerdiği, denize göre değişen, genel olarak yüzlerce bazen binlerce metreye varan su derinliği. (tr)
  • The carbonate compensation depth, or CCD, is defined as the water depth at which the rate of supply of calcium carbonate from the surface is equal to the rate of dissolution. As long as the ocean floor lies above the CCD, carbonate particles will accumulate in bottom sediments, but below, there is no net accumulation.
