The Antarctic Ocean is the coldest ocean in the world. Its temperatures reach minus 2 degrees Celsius in what is referred to as the Antarctic bottom water.
The water at the surface of the Antarctic Ocean can be minus 2 degrees Celsius, which is below the zero degrees Celsius freezing point for water, explains the National Oceanic and Atmospheric Administration,. However, due to the high concentration of salt in the seawater, it is still liquid at this temperature.
Oceanographers have found that the Antarctic bottom water supply has been reducing an average of eight million metric tons per second over the past few decades. They argue that this decrease is the result of changes in Earth's climate.Learn More
According to Science and the Sea, lunar tides are the most common tides and are caused by the Moon's gravity. Although the Sun's gravity is stronger, it is farther from the Earth than the Moon, which is why lunar tides are more than two times stronger than solar tides.Full Answer >
The basic lunar cycle of a body of water consists of two high tides and two low tides, which occur every 24 hours and 50 minutes. The basic cycle of solar tides is 24 hours.Full Answer >
Cyclones cause widespread flooding and wind damage. Flood damage results from the combination of torrential rain, which overwhelms the soil’s ability to absorb it, and storm surges, which force significant quantities of water up onto the shore in front of the storm. Wind damage results from the straight-line winds produced by the cyclone and tornadoes that the cyclone spawns.Full Answer >
The term "El Nino" describes unusually warm ocean water temperatures in the Equatorial Pacific region. Relaxed trade winds in the Pacific cause this phenomenon by stalling the upwelling of colder, nutrient-rich water to the surface.Full Answer >
