lysocline

English edit

From Ancient Greek λύσις (lúsis, “loosening, breaking loose”) +‎ -cline.

lysocline (plural lysoclines)

The depth in the ocean below which solubility of calcium carbonate (CaCO₃) increases dramatically.
- 2009 January 16, R. W. Wilson et al., “Contribution of Fish to the Marine Inorganic Carbon Cycle”, in Science‎^[1], volume 323, number 5912:
  The causes of CaCO₃ dissolution above the lysocline are subject to debate and have been attributed to (i) dissolution in zooplankton guts; (ii) dissolution in microenvironments where bacterial oxidation of organic matter enhances this process; and (iii) dissolution of more soluble forms of CaCO₃, including pteropods and high-magnesium calcite.
