Global warming is altering the biogeochemical cycles of key elements in marine and terrestrial environments, i.e. C, S, N, P…, creating potential feedback on future climate. Understanding, monitoring and predicting these processes bear global societal and economic implications.

Our mission:

To increase knowledge on ecosystems and biogeochemical processes in deep-sea extreme environments, i.e. methane and oil seeps, gas hydrates, and hydrothermal vents, and in shallow aquatic systems impacted by anthropogenic activities such as fjords, lakes and coastal areas.

We combine field work (marine research expeditions, field trips), experimental studies (biological, molecular and isotopic analyses), sediment characterization (sedimentology, lithostratigraphy), and numerical models to quantify elemental fluxes through the bio-geo-hydrospheres.

Multidisciplinary approach:

We believe in the importance of applying a multidisciplinary approach to solve scientific questions and for that reason, we include collaborations from many fields e.g., microbiology, environmental sciences, molecular biology, and geophysics.

Research areas:

Cold seeps and hydrothermal vents
Environmental geology
Environmental biogeochemistry in marine and terrestrial aqueous systems affected by human activities
Micropaleontology and environmental DNA (eDNA)
Sediment and pore fluid geochemistry
Marine authigenic carbonates

Research objectives:

To reconstruct past hydrocarbon and hydrothermal activities at Arctic sites using (micro)faunal and geochemical proxies (sediment and pore fluids) on sediment cores
To characterize the composition and distribution of seafloor chemosynthetic ecosystems at cold seeps and vents in relation to subsurface geochemical gradients
To reconstruct the history of hydrothermal activity at the Arctic mid-ocean ridge using (micro)faunal and geochemical proxies on sediment cores
To study the effect of submarine mine tailing disposal on seafloor communities and quantify metal fluxes in/out of the sediment
To understand and quantify the impact of human activities on the environments
