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 ]
Methane (CH 4) is one of the more potent greenhouse gases and is mainly produced by the digestion or decay of biological organisms. It is considered the second most important greenhouse gas, [10] yet the methane cycle in the atmosphere is currently only poorly understood. [11] The amount of methane produced and absorbed yearly varies widely. [10]
Methane (CH 4) concentrations in the atmosphere measured by the Advanced Global Atmospheric Gases Experiment (AGAGE) in the lower atmosphere (troposphere) at stations around the world. Values are given as pollution free monthly mean mole fractions in parts-per-billion. [1] Atmospheric methane is the methane present in Earth's atmosphere. [2]
Water is the medium of the oceans, the medium which carries all the substances and elements involved in the marine biogeochemical cycles. Water as found in nature almost always includes dissolved substances, so water has been described as the "universal solvent" for its ability to dissolve so many substances.
The diagram on the left shows a simplified budget of ocean carbon flows. It is composed of three simple interconnected box models, one for the euphotic zone, one for the ocean interior or dark ocean, and one for ocean sediments. In the euphotic zone, net phytoplankton production is about 50 Pg C each year. About 10 Pg is exported to the ocean ...
This is methane gas, spewing from an energy facility in Italy,caught on infrared footage that’s been made available to Reuters.It’s one example of many.The potent greenhouse gas is seeping ...
A cold seep (sometimes called a cold vent) is an area of the ocean floor where seepage of fluids rich in hydrogen sulfide, methane, and other hydrocarbons occurs, often in the form of a brine pool. Cold does not mean that the temperature of the seepage is lower than that of the surrounding sea water; on the contrary, its temperature is often ...
