The air-sea CO 2 flux induced by a marine biological community can be determined by the rain ratio - the proportion of carbon from calcium carbonate compared to that from organic carbon in particulate matter sinking to the ocean floor, (PIC/POC). [19] The carbonate pump acts as a negative feedback on CO 2 taken into the ocean by the solubility ...
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 ...
Illustration showing methane chimney from sea floor to surface. A methane chimney or gas chimney is a rising column of natural gas, mainly methane, within a water or sediment column. The contrast in physical properties between the gas phase and the surrounding water makes such chimneys visible in oceanographic and geophysical data.
The world saw a record jump in levels of methane in the atmosphere last year as the main heat-trapping greenhouse gases reached new highs, UN experts said. ... ocean warming and sea level rise.” ...
Scientists have discovered an active methane seep from Antarctica's sea bed that could shed light on the potent greenhouse gas trapped beneath frozen continent. Marine ecologist Andrew Thurber ...
Changing atmospheric and oceanic temperatures may impact the presence and depth of the hydrate stability zone, however, is still uncertain to what extent. In oceanic sediments, increasing pressure due to a rise in sea level may offset some of the impact of increasing temperature upon the hydrate stability equilibrium. 1 [citation needed]
The amount of CO2 in the atmosphere reached a record high in 2016, according to the World Meteorological Organization (WMO). Thanks to a combination of human activities and the El Nino weather ...
Dissolved salt does not evaporate back into the atmosphere like water, but it does form sea salt aerosols in sea spray. Many physical processes over ocean surface generate sea salt aerosols. One common cause is the bursting of air bubbles , which are entrained by the wind stress during the whitecap formation.
