They are said to be “undersaturated.” Shallow, warm surface waters are described as “supersaturated” with respect to both calcite and aragonite, meaning that these minerals have no tendency to dissolve.
海洋浅层的温暖海水，对方解石和霰石则为「过饱和」，代表这两种矿物不倾向溶解。
The Red Sea is supersaturated in both calcite and aragonite and the degrees of saturation are higher than found in the Gulf of Aden.
