The Revelle factor (buffer factor) is the ratio of instantaneous change in carbon dioxide (CO 2) to the change in total dissolved inorganic carbon (DIC), and is a measure of the resistance to atmospheric CO 2 being absorbed by the ocean surface layer. [1]
By doing so, the ocean has acted as a buffer, somewhat slowing the rise in atmospheric CO 2 levels. However, this absorption of anthropogenic CO 2 has also caused acidification of the oceans. [8] [10] Climate change, a result of this excess CO 2 in the atmosphere, has increased the temperature of the ocean and atmosphere. [11]
Carbon dioxide molecule.. pCO 2, pCO 2, or is the partial pressure of carbon dioxide (CO 2), often used in reference to blood but also used in meteorology, climate science, oceanography, and limnology to describe the fractional pressure of CO 2 as a function of its concentration in gas or dissolved phases.
Ocean heat content (OHC) or ocean heat uptake (OHU) is the energy absorbed and stored by oceans. To calculate the ocean heat content, it is necessary to measure ocean temperature at many different locations and depths. Integrating the areal density of a change in enthalpic energy over an ocean basin or entire ocean gives the total ocean heat ...
The table below gives thermodynamic data of liquid CO 2 in equilibrium with its vapor at various temperatures. Heat content data, heat of vaporization, and entropy values are relative to the liquid state at 0 °C temperature and 3483 kPa pressure. To convert heat values to joules per mole values, multiply by 44.095 g/mol.
[33] [34] [35] A decrease in ocean oxygen levels affects how productive the ocean is, how nutrients and carbon move around, and how marine habitats function. [36] [37] As the oceans become warmer this increases the loss of oxygen in the oceans. This is because the warmer temperatures increase ocean stratification. The reason for this lies in ...
Despite this, changes in the global sea level over the past 3–4 billion years have only been a few hundred metres, much smaller than the average ocean depth of 4 kilometres. Thus, the fluxes of water into and out of the mantle are expected to be roughly balanced, and the water content of the mantle steady.
Deep sea water column The (oceanic) water column is a concept used in oceanography to describe the physical (temperature, salinity , light penetration) and chemical ( pH , dissolved oxygen , nutrient salts) characteristics of seawater at different depths for a defined geographical point.
