What happens when ice mixes with fresh or sea water?

When ice mixes with fresh or seawater, it typically causes the surrounding water to cool, as ice absorbs heat to melt. In freshwater, the ice will float, while in seawater, the higher salinity affects the melting process, leading to a slower melting rate. The resulting mixture can create a stratified layer where the less dense freshwater floats on top of the denser saltwater. Additionally, the melting ice can contribute to changes in salinity and temperature, influencing local aquatic ecosystems.
