Global map of sea surface temperature, showing warmer areas around the equator and colder areas around the poles (20 December 2013 at 1-km resolution). Sea surface temperature (SST), or ocean surface temperature, is the water temperature close to the ocean's surface.
The increase of both ocean surface temperature and deeper ocean temperature is an important effect of climate change on oceans. [11] Deep ocean water is the name for cold, salty water found deep below the surface of Earth's oceans. Deep ocean water makes up about 90% of the volume of the oceans. Deep ocean water has a very uniform temperature ...
Thermohaline circulation ( THC) is a part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes. [1] [2] The adjective thermohaline derives from thermo- referring to temperature and -haline referring to salt content, factors which together determine the density of sea water.
Land surface temperatures have increased faster than ocean temperatures as the ocean absorbs about 92% of excess heat generated by climate change. [10] Chart with data from NASA [11] showing how land and sea surface air temperatures have changed vs a pre-industrial baseline.
The Atlantic meridional overturning circulation (AMOC) is the main current system in the Atlantic Ocean, [ 1]: 2238 and is also part of the global thermohaline circulation, which connects the world's oceans with a single "conveyor belt" of continuous water exchange. [ 29] Normally, relatively warm, less-saline water stays on the ocean's surface ...
Averaged winter sea surface temperatures in the western Pacific Ocean using satellite data. The Kuroshio current is warm, compared to cooler waters in the Yellow Sea , and Sea of Japan. The Kuroshio is a relatively warm ocean current with an annual average sea-surface temperature of about 24 °C (75 °F), is approximately 100 kilometres (62 mi ...
An ocean current is a continuous, directed movement of seawater generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences. [1] Depth contours, shoreline configurations, and interactions with other currents influence a current's direction and ...
The sea surface skin temperature ( SSTskin ), or ocean skin temperature, is the temperature of the sea surface as determined through its infrared spectrum (3.7–12 μm) and represents the temperature of the sublayer of water at a depth of 10–20 μm. [1] High-resolution data of skin temperature gained by satellites in passive infrared ...
