Use our Ocean Water Freezing Point Calculator to quickly determine the exact temperature at which seawater freezes, considering its salinity. This tool is vital for marine biologists, oceanographers, and anyone studying polar environments, understanding sea ice formation, and oceanic processes. Simplify complex calculations instantly.
Formula:
The approximate freezing point of ocean water (Tf) can be calculated using the following empirical formula:
Tf = -0.0186 * S
- Tf: Freezing Point of Seawater in degrees Celsius (°C)
- S: Salinity in Practical Salinity Units (PSU or ‰)
This formula highlights that for every PSU increase in salinity, the freezing point of water decreases by approximately 0.0186 °C from the freezing point of pure water (0°C).
