👉 Ice fluid, also known as brine or liquid water within ice, is a unique state of water that forms when ice crystals grow and incorporate small amounts of liquid water. This occurs primarily in polar regions and glaciers, where temperatures are consistently below freezing but the pressure and salinity conditions allow water to remain liquid. The ice fluid is typically less dense than solid ice, contributing to the buoyancy of floating icebergs and sea ice. It plays a crucial role in the dynamics of ice sheets and glaciers, influencing their movement and stability, as well as impacting ocean circulation and climate systems.
