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 ... -
Mapping Microbial Abundance and Prevalence to Changing Oxygen Concentration in Deep-Sea Sediments Using Machine Learning and Differential Abundance
Møller, Tor Einar; Moine-Bauer, Sven Le; Hannisdal, Bjarte; Zhao, Rui; Baumberger, Tamara; Roerdink, Desiree Lisette; Dupuis, Amandine; Thorseth, Ingunn Hindenes; Pedersen, Rolf B.; Jørgensen, Steffen Leth (Journal article; Peer reviewed, 2022)Oxygen constitutes one of the strongest factors explaining microbial taxonomic variability in deep-sea sediments. However, deep-sea microbiome studies often lack the spatial resolution to study the oxygen gradient and ... -
The Seven Sisters Hydrothermal System: First Record of Shallow Hybrid Mineralization Hosted in Mafic Volcaniclasts on the Arctic Mid-Ocean Ridge
Marques, Ana Filipa Alfaia; Roerdink, Desiree; Baumberger, Tamara; de Ronde, Cornel; Ditchburn, Robert; Denny, Alden Ross; Thorseth, Ingunn Hindenes; Økland, Ingeborg; Lilley, Marvin D.; Whitehouse, Martin, J.; Pedersen, Rolf B. (Journal article; Peer reviewed, 2020)We document the discovery of an active, shallow, seafloor hydrothermal system (known as the Seven Sisters Vent Field) hosted in mafic volcaniclasts at a mid-ocean ridge setting. The vent field is located at the southern ...
