Ocean heat content
In oceanography and climatology, ocean heat content (OHC) is a term for the energy absorbed by the ocean, which is stored for indefinite time periods as internal energy or enthalpy. Ocean warming accounts for about 90% of Earth's energy accumulation from global warming since year 1970. About one third of this added thermal energy has propagated to depths below 700 meters as of 2020. Changes in ocean heat content have far-reaching consequences for the planet's marine and terrestrial ecosystems; including multiple impacts to coastal ecosystems and communities.The more abundant equatorial solar irradiance which is absorbed by Earth's tropical surface waters drives the overall poleward propagation of ocean thermal energy. Warming oceans are directly responsible for coral bleaching and contribute to the migration of marine species. Redistribution of the planet's internal energy by atmospheric circulation and ocean currents produces internal climate variability, often in the form of irregular oscillations, and helps to sustain the global thermohaline circulation. Marine heat waves are regions of life-threatening and persistently dense ocean heat. Releases of OHC to the atmosphere occur primarily via evaporation and enable the planetary water cycle. Concentrated releases in association with high sea-surface temperatures help drive tropical cyclones, atmospheric heat waves and other extreme weather events.The increase in OHC accounts for 30-40% of global sea-level rise from 1900 to 2020 because of thermal expansion. It is also an accelerator of sea ice, iceberg, and tidewater glacier melting. The resulting ice retreat has been most consistent and pronounced for Arctic sea ice, and within northern fjords such as those of Greenland and Canada. Impacts to Antarctic sea ice and the vast Antarctic ice shelves which terminate into the Southern Ocean have been more varied.

Examples of ocean heat content in a Sentence
The heat fuels storms of all sorts and contributes to very heavy rain events and flooding, the observed increases of upper( ocean heat content) support higher sea surface temperatures and atmospheric moisture, and fuel tropical storms to become more intense, bigger and longer-lasting, thereby increasing their potential for damage.
