My latest paper is now out in Limnology and Ocenography Letters @aslo.org, titled "Emerging patterns of CO2 : O2 dynamics in rivers and their link to ecosystem carbon processing". It is open access, so go read! I am mostly proud of this figure, which I spent a lot of hours figuring out how to do it
