    "data": {
        "note": "The freezing point of seawater (Millero) drops with salinity — about −1.9 °C at the ocean's typical 35 ppt, versus 0 °C for fresh water. Because salt also lowers the temperature of maximum density below the freezing point, seawater keeps overturning and cooling all the way to freezing instead of stratifying like a freshwater lake — which is why the open ocean rarely freezes except in the polar seas, and the ice that forms is nearly salt-free.",
