Figure 1: Range of potential soil N 2 O sink capacity. Figure 3 ... Portmann, R. W. Nitrous oxide (N2O): The dominant ozone-depleting substance emitted in the 21st century. Science 326, 123 ...

Similar N2O “sinks” have been described previously in other pristine systems, including estuaries, mangroves and even terrestrial soils. The ability of these areas to draw N2O from the ...

A new greenhouse gas budget shows coastal ecosystems globally are a net greenhouse gas sink for carbon dioxide (CO2) but emissions of methane (CH4) and nitrous oxide (N2O) counteract some of the ...

And the gas continues to accumulate. A 2020 review of nitrous oxide sources and sinks found that emissions rose 30% in the last four decades and are exceeding all but the highest potential ...

A blue arrow indicates the reduction in N2O emissions provided by chemical reactions in the upper atmosphere (“atmospheric chemical sink”). On the infographic, average N2O emissions are shown in ...

Sediments that act as N2O sinks can also act as net sources of N2O to the atmosphere when subjected to increased nitrogen loading from agricultural runoff and urban waste water. Indeed ...

Similar N2O “sinks” have been described previously in other pristine systems, including estuaries, mangroves and even terrestrial soils. The ability of these areas to draw N2O from the ...

When nutrient levels are sufficiently low, marine habitats can act as net consumers of N2O. Sediments that act as N2O sinks can also act as net sources of N2O to the atmosphere when subjected to ...
