Serpentinization-driven H2 production from continental break-up to mid-ocean ridge spreading: unexpected high rates at the West Iberia margin
;
; ; ; (2021)
Molecular hydrogen (H2) released during serpentinization of mantle rocks is one of the main fuels for chemosynthetic life. Processes of H2 production at slow-spreading mid-ocean ridges (MORs) have received much attention ... -
Fluid–rock interactions in the shallow Mariana forearc: carbon cycling and redox conditions
;; ; ; ; (2019)
Few data exist that provide insight into pro- cesses affecting the long-term carbon cycle at shallow fore- arc depths. To better understand the mobilization of C in sediments and crust of the subducting slab, we investigated ... -
Past penguin colony responses to explosive volcanism on the Antarctic Peninsula
;; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; (2017)
Changes in penguin populations on the Antarctic Peninsula have been linked to several environmental factors, but the potentially devastating impact of volcanic activity has not been considered. Here we use detailed ... -
Impact of increasing carbon dioxide on dinitrogen and carbon fixation rates under oligotrophic conditions and simulated upwelling
; ; ; ; ; (Limnology and Oceanography, 2021-06-04)
Dinitrogen (N2) fixation is a major source of bioavailable nitrogen to oligotrophic ocean communities. Yet, we have limited understanding how ongoing climate change could alter N2 fixation. Most of our understanding is ...
