Calcium, alkalinity, and magnesium: how they shape coral growth

 Calcium, alkalinity, and magnesium: how they shape coral growth

Corals build their reefs by turning dissolved seawater chemistry into calcium carbonate, the mineral that forms their skeleton. While factors like temperature, nutrients, and disease receive much of the attention, the “molecular ingredients” in seawater—particularly calcium, alkalinity, and magnesium—play a direct role in how fast and how reliably corals can grow.

Together, these compounds influence both the materials corals use and the stability of the chemica ... Read more »

The movement isn’t just aesthetics; it reflects a dynamic exchange between current, light, and the coral’s own feeding strategy. Scientists describe it as a coordinated response that helps soft corals capture plankton and detritus suspended in the water column. What ma  ...  Read more »
