Sea surface temperature (SST), or ocean surface temperature, is the water temperature close to the ocean 's surface. 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. The definition proposed by IPCC for sea surface temperature does ...
The Kuroshio Current is the west side of the clockwise North Pacific ocean gyre. The Kuroshio Current ( 黒潮, "Black Tide"), also known as the Black Current or Japan Current ( 日本海流, Nihon Kairyū) is a north-flowing, warm ocean current on the west side of the North Pacific Ocean basin. It was named for the deep blue appearance of its ...
Deep ocean water makes up about 90% of the volume of the oceans. Deep ocean water has a very uniform temperature of around 0-3 °C. Its salinity is about 3.5% or 35 ppt (parts per thousand). [3] Relevance. [edit] Ocean temperature and dissolved oxygenconcentrations have a big influence on many aspects of the ocean.
The temperature is nearly constant after 1500 meters depth. A thermocline (also known as the thermal layer or the metalimnion in lakes) is a distinct layer based on temperature within a large body of fluid (e.g. water, as in an ocean or lake; or air, e.g. an atmosphere) with a high gradient of distinct temperature differences associated with ...
The marine pelagic environment is the largest aquatic habitat on Earth, occupying 1,370 million cubic kilometres (330 million cubic miles), and is the habitat for 11% of known fish species. The oceans have a mean depth of 4,000 metres (2.5 miles). About 98% of the total water volume is below 100 metres (330 ft), and 75% is below 1,000 metres ...
The thermal equator (also known as "the heat equator") is a belt encircling Earth, defined by the set of locations having the highest mean annual temperature at each longitude around the globe. Because local temperatures are sensitive to the geography of a region, mountain ranges and ocean currents ensure that smooth temperature gradients (such ...
Ocean temperature and motion fields can be separated into three distinct layers: mixed (surface) layer, upper ocean (above the thermocline), and deep ocean. Ocean currents are measured in units of sverdrup (sv) , where 1 sv is equivalent to a volume flow rate of 1,000,000 m 3 (35,000,000 cu ft) per second.
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.
