海冰（sea ice）是淡水冰晶、“鹵水”和含有鹽分的氣泡混合體，包括來自大陸的淡水冰（冰川和河冰）和由海水直接凍結而成的咸水冰，一般多指後者。廣義的海冰還包括在海洋中的河冰、冰山等。
咸水冰是固體冰和鹵水（包括一些鹽類結晶體）等組成的混合物，其鹽度比海水低2～10‰，物理性質（如密度、比熱、溶解熱，蒸發潛熱、熱傳導性及膨脹性）不同於淡水冰。

"Sea ice is a mixture of freshwater ice crystals," brine", and bubbles containing salt, including freshwater ice (glaciers and river ice) from the mainland and saltwater ice that is directly frozen from seawater. Generally it refers to the latter. In a broad sense, sea ice also includes river ice and icebergs in the ocean. Salt water ice is a mixture of solid ice and brine (including some salt crystals). Its salinity is 2-10 ‰ lower than that of seawater. Physical properties (such as density, specific heat, heat of solution, latent heat of evaporation, thermal conductivity, and expansion) are different from freshwater ice. "
