Under an Antarctic glacier, a temperature of −2.6°C (27.3°F) was recorded. Ultra-cold water like this forms when sea ice grows.
Using their technique, which measures the drops' temperatures via their diameters, the team showed that the liquid can exist down to −42. 55∘C, the lowest water temperature measured to date.
The Antarctic bottom water (AABW) is a type of water mass in the Southern Ocean surrounding Antarctica with temperatures ranging from −0.8 to 2 °C (35 °F) and absolute salinities from 34.6 to 35.0 g/kg.
Antarctic sea ice
A “supercoolometer”, a device that sounds like it should be used to measure hipsters, has found the coldest seawater on Earth, under Antarctic sea ice.
At midlatitudes the mid-ocean temperatures vary about 8 °C (14.4 °F) over the year. At the polar latitudes the surface temperature remains near the freezing point of seawater, about −1.9 °C (28.6 °F).
Infrared sensors can easily detect sea ice because its temperature is generally much colder than the surrounding ocean. A typical winter sea ice temperature is -20 to -40°C (-4 to -40°F), while the surrounding ocean temperature is at least just above freezing.
First, it usually requires small particles of another solid to be present. “Contrary to popular perception, pure liquid water does not usually freeze at its melting point, 0°C, and can instead supercool to temperatures as low as -38°C.

Answer and Explanation: Y e s , the Arctic Ocean is the coldest ocean, even colder than the waters surrounding Antarctica. Since the Arctic ocean always has sea ice even during summer, the temperature of the surface is… See full answer below.
This results in less warming of the water. Therefore, the deep ocean (below about 200 meters depth) is cold, with an average temperature of only 4°C (39°F).
Ocean water freezes just like freshwater, but at lower temperatures. Fresh water freezes at 32 degrees Fahrenheit but seawater freezes at about 28.4 degrees Fahrenheit , because of the salt in it.
31.8 to 32 degrees Fahrenheit
The Antarctic Bottom Water of the Weddell Sea usually ranges from -0,8 to 0 degrees Celsius (31.8 to 32 degrees Fahrenheit), but surface temperatures are generally below freezing.
Water freezes at 0 degrees Celsius and 32 degrees Fahrenheit. The freezing point is the temperature by which a liquid turns into a solid.
Wether you measure degrees Celsius or Fahrenheit: the lower the figure, the colder it gets. Minus 24 is lower than minus 16. If you convert to absolute temperature in Kelvin, you always get a positive number.
Ocean water freezes at a lower temperature than freshwater.
When seawater freezes, however, the ice contains very little salt because only the water part freezes. It can be melted down to use as drinking water.
Water needs to be at the freezing temperature of 0°C or 32°F for it to freeze.
At temperatures above 32°F (0°C), pure water ice melts and changes state from a solid to a liquid (water); 32°F (0°C) is the melting point.
So, you might be wondering: how cold was the water when the Titanic sank The water was exceptionally cold, averaging around 28°F (-2°C) when the Titanic sank. These freezing temperatures greatly affected the passengers and crew in the shipwreck, as hypothermia quickly set in for those exposed to the water.
If you're healthy and have your skin and airways fully covered, you should be fine outside for 10-minute stints when the windchill is below 0 degrees F, Uren says. But if you're managing a disease, you may need to be extra cautious in extremely cold temperatures. Here's why.
It is mostly covered by sea ice throughout the year and almost completely in winter.
The Arctic Ocean is the world's smallest ocean. It is also the shallowest out of the five major oceans of the world. It covers an area of about 5,430,000 sq mi (14,060,000 km2) and is the coldest out of all the other oceans.
The water temperature on the night of the disaster was 28°F (-2°C), which is below the freezing point of sea water.
At least 15 percent of the ocean is covered by sea ice some part of the year. Ocean water freezes just like freshwater, but at lower temperatures. Fresh water freezes at 32 degrees Fahrenheit but seawater freezes at about 28.4 degrees Fahrenheit , because of the salt in it.
The water was exceptionally cold, averaging around 28°F (-2°C) when the Titanic sank. These freezing temperatures greatly affected the passengers and crew in the shipwreck, as hypothermia quickly set in for those exposed to the water.
The meltwater has a very low content in mineral. The taste is not great but it is fine. The closest one is some mineral waters that also have a very low mineral content. If you want to drink it directly, you may prefer to add a very small amount of salt or some syrup.
