The leakage of cold, methane-rich fluids from subsurface reservoirs to the sea floor at
specific sites on continental slopes, termed cold seeps, sustains some of the richest …

Chemosynthetic symbioses between bacteria and marine invertebrates were discovered 30
years ago at hydrothermal vents on the Galapagos Rift. Remarkably, it took the discovery of …

Abstract The Arctic Mid-Ocean Ridge (AMOR) represents one of the most slow-spreading
ridge systems on Earth. Previous attempts to locate hydrothermal vent fields and unravel the …

Marine sediments are the largest carbon sink on earth. Nearly half of dark carbon fixation in
the oceans occurs in coastal sediments, but the microorganisms responsible are largely …

Siboglinids are tube-dwelling annelids that are important members of deep-sea
chemosynthetic communities, which include hydrothermal vents, cold seeps, whale falls and …

Cold seeps can support unique faunal communities via chemosynthetic interactions fueled
by seabed emissions of hydrocarbons. Additionally, cold seeps can enhance habitat …

The oxidation of hydrogen sulfide is essential to sulfur cycling in marine habitats. However,
the role of microbial sulfur oxidation in marine sediments and the microorganisms involved …

ABSTRACT During the European Commission's Framework Six Programme, HERMES, we
investigated three main areas along the European margin, each characterized by the …

Submarine hydrocarbon seeps are geologically driven" hotspots" of increased biological
activity on the seabed. As part of the HERMES project, several sites of natural hydrocarbon …

The ChEss project of the Census of Marine Life (2002–2010) helped foster internationally-
coordinated studies worldwide focusing on exploration for, and characterization of new deep …
