Geochemistry of hydrothermal fluids from the E2-segment of the East Scotia Ridge: Magmatic input, reaction zone processes, fluid mixing regimes and bioenergetic landscapes

Pereira, Samuel; Diehl, Alexander; McDermott, Jill M; Pape, Thomas; Klose, Lukas; Strauss, Harald; Bohrmann, Gerhard; Bach, Wolfgang (Journal article; Peer reviewed, 2022)

The compositions of hydrothermal fluids in back-arc basins (BABs) can be affected by the influx of magmatic fluids into systems that are dominated by reactions between basement rocks and seawater-derived fluids. The East ...
Hydrothermal activity fuels microbial sulfate reduction in deep and distal marine settings along the Arctic Mid Ocean Ridges

Roerdink, Desiree Lisette; Vulcano, Francesca; Landro, Jan-Kristoffer; Moltubakk, Karen Elisabeth; Babel, Hannah Rose; Jørgensen, Steffen Leth; Baumberger, Tamara; Økland, Ingeborg Elisabet; Reeves, Eoghan; Thorseth, Ingunn Hindenes; Reigstad, Laila Johanne; Strauss, Harald; Steen, Ida Helene (Journal article; Peer reviewed, 2023)

Microbial sulfate reduction is generally limited in the deep sea compared to shallower marine environments, but cold seeps and hydrothermal systems are considered an exception. Here, we report sulfate reduction rates and ...
