Temperatures below freezing are a problem for gardeners. Fortunately, most plants have evolved strategies to prevent frost damage to cells and tissues at low winter temperatures.
Icebergs floating in the ocean belong to fresh water. Even if they form directly from seawater, the solid ice only contains water molecules. The salt remains in the sea and increases the salt concentration there or is trapped in caverns and other cavities in the ice. The reason can be shown in the phase diagram of the water / sodium chloride system. Salts dissolve in water up to a certain temperature - dependent concentration. If more salt is added, there will be solid salt crystals on the bottom in addition to the saturated solution.
