TL;DR: In this paper, the in situ rates of sulfate reduction and anaerobic methane oxidation in 2-3m-long sediment cores were made, with a broad maximum below the sediment surface and a smaller, narrow maximum at the sulfate-methane transition.

TL;DR: In this article, the authors proposed a relation between D[sub 0] and [phi] using a constant (n) over a wide porosity range (0.4-0.9), with a better fit than is possible by using Archie's relation with a constant exponent.

TL;DR: In this study the soil methane-oxidizing population was characterized by both labelling soil microbiota with14CH4 and analyzing a total soil monooxygenase gene library, and an unknown group of bacteria belonging to the α subclass of the class Proteobacteria was present.

TL;DR: The results suggest that the isotope array can be used in a PCR-independent manner to exploit the high parallelism and discriminatory power of microarrays for the direct identification of microorganisms which consume a specific substrate in the environment.

TL;DR: In this article, the authors measured salinity profiles in nine tidal estuaries in Europe (Elbe, Ems, Thames, Rhine, Scheldt, Loire, Gironde, Douro and Sado) and found that dissolved methane initially decreases with increasing salinity, then increases to a maximum at intermediate to high salinities before decreasing again going offshore.
