Expertise

  • Pulse-chase experiments with stable isotopes (SI)
  • Compound-specific isotope analysis (fatty acids, amino acids)
  • Linear inverse modelling of benthic food-webs
  • Absorbance and fluorescence measurements of DOM (CDOM, FDOM)

Research interests

  •            Carbon cycle in polar waters and sea ice
  •       Structure and stability of deep-sea food webs
  •       Nutrient and oxygen fluxes of benthic megafauna (e.g. Porifera, Holothuroidea)
  •       Environmental impact of deep-sea mining
  •       Deep-sea megafauna densities and biomass

Short-term effects of deep-sea mining waste on microbes and meiofauna at the seafloor
The addition of waste particles from deep-sea mining (iron ore mine tailings) affected the activity of nematodes and the microbial community in microcosm experiments with natural sediments collected at 200m depth in the Hardanger fjord (Norway).…
