Clumped isotopologue fractionation by microbial cultures performing the anaerobic oxidation of methane
Published 2021“…We investigated the methane isotopologue fractionations during AOM in experiments with cultures of ANME-1 archaea and partner bacteria obtained from hydrothermally heated gas-rich sediments of the Guaymas Basin. During partial methane consumption in four sets of experiments, residual methane became enriched in 13CH4 and 12CH3D, following kinetic fractionations from 11.1 to 18.3‰ and from 117 to 180‰, respectively. …”

Discovering hydrothermalism from Afar: In Situ methane instrumentation and change-point detection for decision-making
Published 2022“…Here, we use <jats:italic>in situ</jats:italic> methane sensors to complement standard sensing technology for hydrothermalism discovery and compare sensors on a towed rosette and an autonomous underwater vehicle (AUV) during a 17 km long transect in the Northern Guaymas Basin in the Gulf of California. This transect spatially intersected with a known hydrothermally active venting site. …”

Genomic characterization of the bacterial phylum Candidatus Effluviviacota, a cosmopolitan member of the global seep microbiome
Published 2024-08-01“…Here, we examined 30 bacterial metagenome-assembled genomes (MAGs) from cold seeps in the South China Sea, the Indian Ocean, the Scotian Basin, and the Gulf of Mexico, as well as from deep-sea hydrothermal sediments in the Guaymas Basin, Gulf of California. Phylogenetic analyses of these MAGs indicate that they form a distinct phylum-level bacterial lineage, which we propose as a new phylum, Candidatus Effluviviacota, in reference to its preferential occurrence at diverse seep areas. …”
