Concept information

Preferred term

sea ice  

Definition

  • Ice formed in the oceans from the freezing of seawater. Due to the salinity of seawater, sea ice requires colder temperatures than pure water to freeze, with –2°C often used as a critical value for formation, and is therefore most extensive in polar regions.
