The Harmony of the Abyss – Revealing the aesthetics and tempo of the mutation of deep ocean geological processes and their links to hydrothermal vents and associated life Open
The study of the geological processes associated with the formation of the ocean floor is fundamental to understand hydrothermal systems in terms of genesis, evolution, duration, cyclicity and spatial distribution as well as the colonizati…

Preservation of Hydrothermal Fluid Copper Isotope Signatures in Chalcopyrite‐Rich Chimneys: A Case Study From the PACMANUS Vent Field, Manus Basin Open
Copper isotopes (δ 65 Cu) in hydrothermal fluids have the potential to provide information on ore‐forming processes occurring below the seafloor, but Cu isotope data from high‐temperature fluids are scarce. Here, we examine the extent to w…

A step towards measuring connectivity in the deep sea: elemental fingerprints of mollusk larval shells discriminate hydrothermal vent sites Open
Deep-sea hydrothermal vent systems are under investigation for base and precious metal exploitations. The impact of mining will depend critically on the ability of larval dispersal to connect and replenish endemic populations. However, ass…

Past and Present Dynamics of the Iron Biogeochemical Cycle Open
This chapter investigates the complexities surrounding the iron biogeochemical cycle from the Archean to present, with a focus on assessing the balance between iron sources and sinks during long periods of Earth's history with relatively i…

Strong geochemical anomalies following active submarine eruption offshore Mayotte Open
Submarine volcanic activity releases large amounts of gases and metals in the water column, affecting biogeochemical cycles and ecosystems at a regional and local scale. In 2018, Fani Maoré submarine volcano erupted 50 km offshore Mayotte …

Boron and Oxygen Isotope Systematics of Two Hydrothermal Systems in Modern Back-Arc and Arc Crust (PACMANUS and Brothers Volcano, W-Pacific) Open
A better characterization of subsurface processes in hydrothermal systems is key to a deeper understanding of fluid-rock interaction and ore-forming mechanisms. Vent systems in oceanic crust close to subduction zones, like at Brothers volc…

Nickel and Chromium Stable Isotopic Composition of Ureilites: Implications for the Earth's Core Formation and Differentiation of the Ureilite Parent Body Open
We report the first Ni and Cr stable isotope data for ureilite meteorites that are the mantle residue of a carbon‐rich differentiated planet. Ureilites have similar Ni stable isotope compositions as chondrites, suggesting that the core‐man…

Evidence for Microbial Carbon and Sulfur Cycling in Deeply Buried Ridge Flank Basalt Open
Sediment-covered basalt on ridge flanks 50 constitutes most of Earth’s oceanic crust, but the composition and metabolic function of its microbial ecosystem is largely unknown. Here, we demonstrate the presence of methane- and sulfur (S)-cy…
