As a marine biologist with a focus on oceanography, I can tell you that the temperature at the bottom of the ocean varies significantly depending on the depth and the location. The deep ocean is generally colder than the surface, with temperatures typically ranging from 1 to 4 degrees Celsius (approximately 34 to 39 degrees Fahrenheit). However, the exact temperature can be influenced by factors such as geothermal heat from the Earth's core, water currents, and the presence of hydrothermal vents. In the context of the information provided, it's important to note that while the freezing point of ocean water is -1.94 degrees Celsius (28.5 degrees Fahrenheit), this is only relevant at or near the surface where sea ice can form. The **average temperature of the ocean surface waters** is about 17 degrees Celsius (62.6 degrees Fahrenheit), which is significantly warmer than the deep ocean. So, to answer your question directly: the temperature at the bottom of the ocean is generally between 1 to 4 degrees Celsius (34 to 39 degrees Fahrenheit), which is colder than the surface but not cold enough to freeze under normal conditions. read more >>

Ocean water, with an average salinity of 35 psu, freezes at -1.94 degrees Celsius (28.5 degrees Fahrenheit). That means at high latitudes sea ice can form. The average temperature of the ocean surface waters is about 17 degrees Celsius (62.6 degrees Fahrenheit).read more >>
