The ocean heat content (OHC) has been increasing for decades as the ocean has been absorbing most of the excess heat resulting from greenhouse gas emissions from human activities. [1] The graph shows OHC calculated to a water depth of 700 and to 2000 meters. Ocean heat content (OHC) or ocean heat uptake (OHU) is the energy absorbed and stored ...

Estimating climate sensitivity from Industrial Age data requires an adjustment to the equation above. The actual forcing felt by the atmosphere is the radiative forcing minus the ocean's heat uptake, H (W/m 2) and so climate sensitivity can be estimated: = / ().

Relationship of phosphate to nitrate uptake for photosynthesis in various regions of the ocean. Note that nitrate is more often limiting than phosphate. The Redfield ratio or Redfield stoichiometry is the consistent atomic ratio of carbon, nitrogen and phosphorus found in marine phytoplankton and throughout the deep oceans.
Earth experienced its sixth warmest year on record in 2021, continuing a trend where each of the past four decades has ranked hotter than the one before it.
However, the ocean heat uptake has doubled since 1993 and oceans have absorbed over 90% of the extra heat of the Earth since 1955. [13] The temperature in the ocean, up to approximately 700 meters deep into the ocean, has been rising almost all over the globe. [12] The increased warming in the upper ocean reduces the density of the upper ≈500 ...
The General Bathymetric Chart of the Oceans (GEBCO) is a publicly available bathymetric chart of the world's oceans. The project was conceived with the aim of preparing a global series of charts showing the general shape of the seafloor. Over the years it has become a reference map of the bathymetry of the world's oceans for scientists and others.
