Sea surface temperature (or ocean surface temperature) is the temperature of ocean water close to the surface. The exact meaning of surface varies in the literature and in practice. It is usually between 1 millimetre (0.04 in) and 20 metres (70 ft) below the sea surface. Sea surface temperatures greatly modify air masses in the Earth's ...
The Blob (Pacific Ocean) The Blob is an anomalous body having sea surface temperature much above normal, seen here in a graphic of April 2014 by the NOAA. The Blob is a large mass of relatively warm water in the Pacific Ocean off the coast of North America that was first detected in late 2013 and continued to spread throughout 2014 and 2015 ...
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 ...
Pacific decadal oscillation. The Pacific decadal oscillation ( PDO) is a robust, recurring pattern of ocean-atmosphere climate variability centered over the mid-latitude Pacific basin. The PDO is detected as warm or cool surface waters in the Pacific Ocean, north of 20°N. Over the past century, the amplitude of this climate pattern has varied ...
El Niño is strictly related to water temperatures near the equator in the eastern Pacific Ocean. In April, NOAA issued an El Niño watch , saying there is a 62% chance of the phenomenon ...
Unlike surface temperatures which decrease with latitude, deep-ocean temperatures are relatively cold and uniform in most regions of the world. [24] About 50% of all ocean volume is at depths below 3000 m (1.85 miles), with the Pacific Ocean being the largest and deepest of five oceanic divisions. The thermocline is the transition between upper ...
Argo (oceanography) The distribution of active floats in the Argo array, colour coded by country that owns the float, as of February 2018. Argo is an international programme for researching the ocean. It uses profiling floats to observe temperature, salinity and currents. Recently it has observed bio-optical properties in the Earth's oceans.
Higher water temperatures allow storms to intensify quicker, and ocean temperatures of at least 26.5°C (79.7°F) are needed to maintain a tropical cyclone. According to NOAA, north Caribbean ...
