Stefan Bünz – Team leader
Gas Hydrate and Free Gas Reservoirs

How much carbon is stored in today’s methane hydrate and free gas reservoirs in the Arctic and how much is susceptible to climate change? At what rates, by which means, and under which circumstances is methane expelled from sub-seabed reservoirs to the seabed? Gas hydrate, shallow gas, geo hazards, continental slope stability, high-latitude sedimentary processes, petroleum systems, CO2-storage, seafloor ecosystems, tectonic and non-tectonic faulting, and the development of sedimentary basins.

Claudio Argentino – Post Doctoral Fellow
Gas Hydrates and Free Gas Reservoirs project group.


Dynamics and history of fluid flow systems in the SW Barents Sea at the Leierdjupet Fault Complex (LFC). In particular, Claudio will work on pore water and sediment geochemistry to determine the origin of the hydrocarbons and the biogeochemical processes occurring in the sediments. 

Marie Stetzler, PhD candidate
Gas in the Water Column research group.

Distribution of greenhouse gases in the water column emanating from arctic seepages. How much of the methane released from the seafloor reaches the upper water column and/or the atmosphere? Over what horizontal and vertical distances do ocean currents transport methane plumes? Observe and model the transport of methane plumes.

Determine the amount of dissolved methane beneath the seafloor boundary layer. Determine and model methane fluxes from the seafloor to the sea surface. https://cage.uit.no/employee/marie-stetzler/

Frank Jakobsen, PhD candidate

Palaeo-glaciology and possible relations to underlying carbon reservoirs on the NE Greenland shelf.

The Role of Ice Ages work group: long-term variability of methane storage and release forced by glacial advance and retreat over the past 2.7 million years).

Kate Waghorn

Post Doctoral Fellow, Gas Hydrate and Free Gas Reservoirs research group.

My research interests include the dynamics and history of fluid flow systems in glaciated margins. I also study fluid flow systems, origin and fluid-rock interactions on mid-ocean spreading ridges and transform faults. I work predominantly with geophysical data to characterize fluid migration and redistribution regimes in the subsurface and relationships between fluid flow and tectonic stresses. My current projects involve understanding how ice sheets altered shallow subsurface fluid flow regimes and modelling fluid cycling on transform faults.

Ida Helene Steen, Professor, Department of Biological Sciences (BIO)

Physiology of microorganisms living in deep-sea hydrothermal vent systems by the use of culturing, molecular biology, biochemistry and geochemistry.

  • What is the diversity of energy metabolisms of hydrothermal vents microorganisms?
  • How do they link the cycling of carbon, nitrogen and sulfur in the system?
  • Do they have enzymes useful in biotechnology?

Eoghan Reeves, Associate Professor, in Aqueous Geochemistry

Department of Earth Science

My hydrothermal research group aims to understand how high temperature and pressure geologic fluids in the Earth’s crust acquire their chemical compositions, specifically how they interact with Earth’s lithosphere and biosphere.

  • biogeochemical processes controlling the formation and evolution of seafloor hot spring fluids and their inorganic-organic chemistry
  • the chemistry of carbon compounds and carbon-sulfur interactions in hydrothermal settings and petroleum systems
  • exploration and sampling of new hydrothermal systems in the deep ocean

Marine ecologist and project manager of deep-sea chemosynthetic environments programme within the Census of Marine Life decade (2004-2010), established INDEEP (International network of scientific investigations of deep-sea ecosystems, 2011-2020) to address knowledge gaps. Since 2013 co-founded and co-led the Deep-Ocean Stewardship Initiative (DOSI) which seeks to integrate science, technology, policy, law and economics to advise policy on ecosystem-based management of resource use in the deep ocean and strategies to maintain the integrity of deep-ocean ecosystems within and beyond national jurisdiction.  www.dosi-project.org
