Sentences with phrase «sinks from photosynthesis»

The findings will help scientists disentangle inputs and outputs in places like the Amazon rainforest, where there are both big emissions from deforestation and big sinks from photosynthesis.

Not exact matches

Forests remove carbon from the air during photosynthesis and store it in wood and roots, making these forests what scientists call carbon sinks.
Because carbon cycle processes such as photosynthesis fractionate the heavy isotope 13C from the lighter 12C, isotopic analysis can usually be used to «trace» sources and sinks of carbon.
Not so much by direct photolysis of water vapor (not generally a lot of that in the stratosphere), but from CH4, which could build up in a nearly oxygen - free atmosphere, and being largerly of biotic origin, with the H coming from photosynthesis (releasing O); O2 buildup itself was delayed because of geologic O2 sinks (in particular, the conversion of ferrous Fe (naturally present in the crust and mantle and which can dissolve in the oceans) to ferric Fe (precipitates out of the water, the source of banded - iron formations, which humans have used to get Fe).
Not only are they one of the most important carbon sinks, storing more carbon than both the atmosphere and the world's oil reserves, they also constantly remove carbon from the atmosphere through photosynthesis, which converts atmospheric carbon to organic matter.
The main natural sinks are the oceans and plants and other organisms that use photosynthesis to remove carbon from the atmosphere by incorporating it into biomass.
where Ea represents annual carbon emissions from anthropogenic sources (fossil fuel use and land use change), En represents the carbon emissions from all natural sources (the oceans, soil respiration, volcanos etc.) and Un represent the uptake of carbon by all natural carbon sinks (oceans, photosynthesis, etc.).
Is there any likelihood a bloom of plankton (from a freshwater pulse, or fallout of a dust cloud full of minerals, for example) would change the temperature of the surface water (change the reflectivity, I suppose, or change how much is absorbed by making more complicated molecules for photosynthesis)-- sufficient to make the water mass density change, affecting whether it sinks or not?
