Our paper on the coupling between microbial degradation of marine particles and their sinking speed, led by Uria, was recently published in Nature Geoscience. This work demonstrates that particles that are sinking faster experience enhanced degradation due to the removal of degradation by-products by flow, letting bacterial enzymes focus on breaking down the particle material itself. A model developed by François showed that this coupling could play a significant role in setting the observed attenuation of carbon flux with depth in the marine environment. Article from ETH here.
