NASA’s new Orbiting Carbon Observatory shows potential tectonically-induced CO2 input from the ocean?

Guest essay by Martin Hovland, Geophysiscist and Professor Emeritus, Center for Geobiology, University of Bergen, Norway The newly released satellite OCO2-data indicates that there is CO2 input in tectonically active oceanic areas. This becomes evident by pairing seafloor topography and tectonic data with the recently published OCO2-results. Thus, in the released OCO2 dataset, showing the…

Global Atmospheric Carbon Dioxide

Global atmospheric carbon dioxide concentrations from Oct. 1 through Nov. 11, as recorded by NASA's Orbiting Carbon Observatory-2. Carbon dioxide concentrations are highest above northern Australia, southern Africa and eastern Brazil. Preliminary analysis of the African data shows the high levels there are largely driven by the burning of savannas and forests. Elevated carbon dioxide can also be seen above industrialized Northern Hemisphere regions in China, Europe and North America.

#AGU14 NASA’s Orbiting Carbon Observatory shows surprising CO2 emissions in Southern Hemisphere

The first global maps of atmospheric carbon dioxide from NASA’s new Orbiting Carbon Observatory-2 mission demonstrate its performance and promise, showing elevated carbon dioxide concentrations across the Southern Hemisphere from springtime biomass burning. At a media briefing today at the American Geophysical Union meeting in San Francisco, scientists from NASA’s Jet Propulsion Laboratory, Pasadena, California;…
