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

More factors not built into climate models.
Ocean warming and CO2 generation. Not that the latter is an issue on its own.

Watts Up With That?

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 average atmospheric concentration of CO2 over a period of about 6 weeks late in 2014, there are three curious, relatively week, but distinct CO2-hotspots over oceanic regions:

1) The Timor CO2-hotspot

2) the Fiji CO2-hotspot, and

3) the Emperor CO2-hotspot, see Fig. 1.
