The coldest temperature recorded in the Arctic Ocean is around -1.8 degrees Celsius (28.8 degrees Fahrenheit). This temperature occurs primarily in the surface layers of the ocean during the winter months when the air temperature drops significantly.
The Arctic region experiences extremely cold conditions, especially during the winter when the sea ice forms and the ocean loses heat to the atmosphere. The freezing point of seawater is lower than that of freshwater due to the presence of salt, which is why temperatures can drop below 0 degrees Celsius without the water actually freezing solid. Despite the cold temperatures, the Arctic Ocean is an essential part of the global climate system and supports various marine life specially adapted to these harsh conditions.
