	abstract = {Four cruises between 2008 and 2012 monitored the continuing eruption of West Mata volcano in the NE Lau Basin as it produced plumes of chemically altered water above its summit. Although large enrichments in He-3, CO2, Fe, and Mn were observed in the plumes, the most notable enrichment was that of H-2, which reached concentrations as high as 14,843 nM. Strongly enriched H-2 concentrations in the water column result from reactions between seawater or magmatic water and extremely hot rocks. In 2008, the observation of elevated H-2 concentrations in the water column above West Mata pointed to vigorous ongoing eruptions at the volcano{\textquoteright}s summit. The eruption was confirmed by visual observations made by the ROV Jason 2 in 2009 and demonstrated that H-2 measurements are a vital instrument to detect ongoing volcanic eruptions at the seafloor. Elevated H-2 in 2010 showed that the eruption was ongoing, although at a reduced level given a maximum H-2 concentration of 4410 nM. In 2012, H-2 levels in the water column declined significantly, to a maximum of only 7 nM, consistent with visual observations from the Quest-4000 ROV that found no evidence of an ongoing volcanic eruption. Methane behaved independently of other measured gases and its concentrations in the hydrothermal plume were very low. We attribute its minimal enrichments to a mixture of mantle carbon reduced to CH4 and biological CH4 from diffuse flow sites. This study demonstrates that ongoing submarine volcanic eruptions are characterized by high dissolved H-2 concentrations present in the overlying water column.},

	abstract = {Mantle rocks exposed on the seafloor constitute a highly reactive chemical and thermal system, in which interaction with seawater to produce serpentinite has major consequences for lithospheric cooling, global geochemical cycles, and microbial activity. Serpentinite-hosted hydrothermal activity is exemplified by the Lost City Hydrothermal Field (30{\textdegree}N, Mid-Atlantic Ridge) where fluid{\textendash}rock reactions in the underlying ultramafic rocks result in high concentrations of abiotic hydrogen, methane, C2+ alkanes, and formate. Such systems have been proposed as possible analogs to the Early Earth environments that gave rise to the first biochemical pathways. Thus, characterizing the local microbial communities and their potential link with abiogenic compounds is of particular significance. Here we demonstrate that in active carbonate chimneys where microbial sulfate reduction is important, up to 50{\%} of the microbial biomass is synthesized from mantle carbon. Conversely, mantle carbon contributes only \~{}10{\%} of the biomass in areas with minimal sulfate reduction. We attribute this difference to greater incorporation of formate or methane by the dominant microbial species, the Lost City Methanosarcinales, in locations where sulfate reducers are able to facilitate this assimilation. The ability of autotrophic communities at Lost City to capitalize on the steady stream of chemical products resulting from serpentinization reactions and to utilize abiogenic mantle carbon lend credence to the hypothesis that early biosynthetic pathways could have developed in similar environments.},
