"The important thing is to not stop questioning. Curiosity has its own reason for existing."
I had the honor of being invited by the editors of the American Journal of Science to contribute a figure from my paper as the cover of the Journal. See Osborn et al., 2012.
This figure is taken from my 2011 paper and has been cited by many. It depicts the dissolved methane concentration as a function of the distance to the nearest gas well in the data that I collected. See Osborn et al., 2011.
