Research Project

  1. Production and consumption of light hydrocarbons in hydrothermal sediments at the Guaymas Basin
  2. Petroleum biodegradation in hydrothermal sediments
  3. Archaeal and bacterial IPLs in methane seep sediments along the northern US Atlantic Margin

Hydrothermally heated sediments from the Guaymas Basin in the Gulf of California is an ideal model location to research on the gas and oil cycling in the marine subsurface environment. Guaymas Basin has a very high sedimentation rate (1 to 2 mm yr-1) and contains thick layers of organic-rich sediments. The complex organic matter is pyrolyzed through venting processes and results in vast quantities of petroleum hydrocarbons.

  • By analyzing the concentrations and13C compositions of light hydrocarbons from methane through pentane, porewater geochemistry and temperature gradients in sediments from a widespread region of the Guaymas Basin, we investigate the formation and consumption of light hydrocarbons in this specific hydrothermal system.
  • Through 13C-labelling incubation experiment with petroleum containing sediments (Guaymas Basin) under low, medium and high temperatures, we aim to investigate the degradation pathways of specific petroleum-like hydrocarbons and the alteration of the whole petroleum complex.

Another part of my PhD thesis focusses on the recently discovered methane seeps along the northern US Atlantic margin, where >570 gas plumes were detected with estimated methane emission of 15-90 Mg yr-1. The methane fluxes vary by location and stimulate anaerobic oxidation of methane (AOM) processes in varying degrees. We analyze the distribution of archaeal and bacterial intact polar lipid (IPL) biomarkers at several sites and aim to investigate the biological controls that govern methane cycling and ultimately large scale methane fluxes from the seabed into the overlying ocean and atmosphere.
