The Research Project

Humankind needs to remove 100-900 gigatons CO2 from atmosphere by the end of the 21st century to keep global warming below 2°C. This herculean task depends on the wide-ranging application of so-called negative emission technologies (NETs). Unfortunately, not a single NET has been proven to function at the gigaton-scale. One of the most promising ideas is to accelerate weathering reactions of minerals that consume CO2 when they dissolve (known as “Ocean Alkalinity Enhancement”). However, the desired consumption of atmospheric CO2 during dissolution would inevitably perturb the oceans with huge amounts of mineral dissolution products (alkalinity, Si, trace metals).

This PhD project will investigate if and how Ocean Alkalinity Enhancement could affect growth and metabolic rates of marine phytoplankton, which are responsible for ~50% of primary production on Earth. The candidate will conduct a range of laboratory incubation experiments and participate in at least one international ship-voyage in the South Pacific. This enables us to cover phytoplankton from different biomes including key functional types, such as diatoms, cyanobacteria and coccolithophores. The overarching goal is to contribute, significantly, to the assessment of Ocean Alkalinity Enhancement as a tool to counteract climate change.

Eligibility
  • Honours or Master degree in biological or chemical oceanography or closely related field (e.g. environmental microbiology). Preferably experience with phytoplankton
  • Great abilities to work in teams and collaborative environments
  • Ability to spend extended periods abroad or on international research vessels during field studies
  • Enthusiasm for scientific discourse and progress
  • Fluent English skills
  • Very good writing skills
  • Reliable and highly motivated
