This material relates to a paper that appeared in the Feb. 10, 2017, issue of Science Advances, published by AAAS. The paper, by G.L. Jessen at Max Planck Institute for Marine Microbiology in Bremen, Germany, and colleagues was titled, 'Hypoxia causes preservation of labile organic matter and changes seafloor microbial community composition (Black Sea).'
