The gas-exchange rate between streams and the atmosphere is needed to measure in-stream ecological processes and C processing in rivers and streams. Current methods include empirical relationships to ...

University of Western Australia provides funding as a founding partner of The Conversation AU. The oceans have absorbed almost 50 % of the CO2 humans released into the atmosphere, which has driven CO2 ...

Knowledge of carbon exchange between the atmosphere, land and the oceans is important, given that the terrestrial and marine environments are currently absorbing about half of the carbon dioxide that ...

OXYGEN enriched with respect to 18 O has been used to solve the problem of how far oxygen, expired by an animal in the form of carbon dioxide, is identical with that inspired as molecular oxygen.

Earth's atmosphere wasn't always full of life-giving oxygen — it was once a choking mixture of carbon dioxide and other gases, more like the atmosphere of Mars or Venus. It's widely believed that the ...
