This process is known as thermohaline circulation. Differences in water density, resulting from the variability of water temperature (thermo) and salinity (haline), also cause ocean currents. The temperature of ocean water also varies with depth. The ocean is a continuous body of salt water that covers more than 70 percent of the Earth's surface. This results in less warming of the water. Whilst sea temperatures for Key West are as accurate as current data allows, there may be slight local and regional variations depending on conditions. The water temperature is constantly near freezing and only a few creatures can be found at these crushing depths. The exact meaning of surface varies according to the measurement method used, but it is between 1 millimetre (0.04 in) and 20 metres (70 ft) below the sea surface. Water warms up more slowly than air but can hold more heat – water needs 4 times as much energy to raise its temperature by 1ºC as the same mass of air does – so the ocean plays an important part in taking up energy from the Sun and stopping the Earth getting too hot. Air masses in the Earth's atmosphere are highly modified by sea surface temperatures within a short distance of the shore. In cold regions, such as the North Atlantic Ocean, ocean water loses heat to the atmosphere and becomes cold and dense. ©Copyright 2012 Ocean Temp | All Rights Reserved | Developed By: WebGuyNYWebGuyNY The Office of Satellite and Product Operations (OSPO) is part of the National Environmental Satellite Data and Information Service (NESDIS). In the ocean, solar energy is reflected in the upper surface or rapidly absorbed with depth, meaning that the deeper into the ocean you descend, the less sunlight there is. Time of day and wind direction may have a temporary local effect as can water flows from neraby rivers. Seawater - Seawater - Temperature distribution: Mid-ocean surface temperatures vary with latitude in response to the balance between incoming solar radiation and outgoing longwave radiation. Quality Sea Surface Temperature Charts. Sea surface temperature (SST) is the water temperature close to the ocean's surface. For example, every 3 to 7 years a wide swath of the Pacific Ocean along the equator warms by 2 to 3 degrees Celsius. There is an excess of incoming solar radiation at latitudes less than approximately 45° and an excess of radiation loss at latitudes higher than approximately 45°. Ocean currents govern the world's weather and churn a kaleidoscope of life. NESDIS is part of the National Oceanic and Atmospheric Administration (NOAA), and the Department of Commerce. Hadalpelagic Zone The deepest zone of the ocean, the hadalpelagic zone extends from 19,700 feet (6,000 meters) to the very bottom at 36,070 feet (10,994 meters) in the Mariana Trench off the coast of Japan. The surface temperature of the world’s oceans varies mainly with latitude, with the warmest waters generally near the equator and the coldest waters in the Arctic and Antarctic regions. Sea surface temperature—the temperature of the water at the ocean surface—is an important physical attribute of the world’s oceans. Deep ocean currents.
