Previous studies of microbial communities in subseafloor sediments reported that microbial
abundance and diversity decrease with sediment depth and age, and microbes dominating …

In seafloor sediments, the anaerobic oxidation of methane (AOM) consumes most of the
methane formed in anoxic layers, preventing this greenhouse gas from reaching the water …

In Croatia, a variety of geothermal springs with a wide temperature range and varied
hydrochemical conditions exist, and they may harbor different niches for the distribution of …

ABSTRACT The Guaymas Basin in the Gulf of California is characterized by active seafloor
spreading, hydrothermal activity, and organic matter accumulation on the seafloor due to …

Abstract In Guaymas Basin, organic-rich hydrothermal sediments produce complex
hydrocarbon mixtures including saturated, aromatic and alkylated aromatic compounds. We …

Introduction Shallow hydrothermal systems share many characteristics with their deep-sea
counterparts, but their accessibility facilitates their study. One of the most studied shallow …

Marine sediments are one of the largest organic carbon (OC) sinks on Earth. Yet, major
knowledge gaps remain in our understanding of sedimentary OC cycling, particularly …

We have developed a model of geospatially estimating carbon accumulation and
methanogenesis in seabed sediments that uses more accurate and sophisticated inputs to …

Introduction Active hydrothermal vents of volcanic origin provide a remarkable manifestation
of life on Earth under extreme conditions, which may have consequences for our …

Discovering new deep hydrothermal vent systems is one of the biggest challenges in ocean
exploration. They are a unique window to elucidate the physical, geochemical, and …
