High-latitude calcareous phytoplankton and zooplankton might share a similar fate, although their declines would come decades later because their shells are formed from calcite, the less soluble form of calcium carbonate.

• 高纬地区的钙质浮游植物和浮游动物可能有相似的命运，虽然它们受到影响的时间也许会晚数十年，因为钙质浮游生物的外壳由方解石形成，这种碳酸钙矿物结晶比较不容易溶解。
