Ph.D. positions in ocean ecological/biogeochemical modeling

ETH Zürich is well known for its excellent education, ground-breaking fundamental research and for implementing its results directly into practice.

Ph.D. positions in ocean ecological/biogeochemical modeling

We are searching for two highly motivated and curious Ph.D. students to jointheEnvironmental Physics Group at ETH Zurich,avibrantinterdisciplinary team of researchersstudyingtheocean, its physics, biogeochemistry, and ecology and their interactions withclimate.A keymotivationdriving our work is to better understandand quantifyhow climate change will impact the ocean, its biogeochemistry, and its ecology, and how these changes mayfeed backon climate.

These two positions are offered in theframework of therecently funded Horizon-EuropeBioGeoSeaproject.

BioGeoSeabrings togethermore than 15partnerinstitutionsacross Europe, with the goaltoimprove our understanding of keybiogeochemical essential ocean observables (EOVs) and their spatiotemporal dynamics and observability. A crucial expected outcome of the project is the better knowledge how to observe a set of biogeochemicalEOVsthat were identified to be criticalindicatorsforthe assessment and monitoring of oceanhealth.A second objective of the project is to improve the representation of the ecological/biogeochemical processes that control these EOVs inocean biogeochemistry and climatemodels, thereby facilitating the interpretation ofpast and presenttrends and variabilityin these variables.The two Ph.D. positionswillcontribute toboth objectives.

Ph.D. position 1:

The firstof thetwodoctoralstudentswill workprimarilyon the marine nitrogen cycleand how it is affected by extreme conditions. The focus will be on the production, consumption and outgassing of nitrous oxide (N2O), a very potent greenhouse gas. But we will be lookingalsoatseveral otherprocesses governing the marine nitrogen cycle, including N2-fixation, denitrification, and anammox, and how they respond to extremes associated with heat (marine heatwaves), low oxygen and/or high acidity.The work, involving models and observations,will start in theoxygen deficient waters of the eastern tropical Pacific, where a large portion of the marine N2O is emitted into the atmosphere, but we plan to extend this also to other regions of the world.

Ph.D. position 2:

Theseconddoctoral student willwork on the improvement of zooplankton processesin our models,focusing ontheir role in structuring the phytoplankton community and in governingthe efficiency of the biological carbon pump.The student will further study food-web interactions and transfer of matter across trophic levels.An essential component will be the assessment of the model results with observations, as well the use of the models to design improved observational strategies.The work will focus on the Southern Ocean, but with an eye toward the application of this improved model across the global ocean.

Both doctoral students will work with configurations of the ETHZ version of the Regional Oceanic Modeling System (ROMS) that we have developed over the last decade.

Profile

As theidealPh.D. student,you haveamaster’sdegree in atmospheric, oceanic and/or climate sciences(PhD 1, PhD2) and/or marine ecology or biology (PhD 2), physics, computational sciences or a closely related disciplinewith a strong interest innumerical andquantitative science.Fluency in Englishand good communication skills is a must, as is experiencewith a higher programming language (e.g., Fortran, C,Matlab, Python).You like to work as part of a team, and love to further your understanding of how the Earth works.Youwill work in the Environmental Physics group of Prof. Nicolas Gruber, and will be co-supervised by Dr. Meike Vogt.

We offer

• Training opportunities with leading experts in modelling, biogeochemical cycles, and ocean processes.
• Support programmes and networking opportunities such as assisting at international conferences.
• An interdisciplinary research group with different interests on processes occurring in the ocean.
• A supportive working environment that values the well-being of the whole group.
• Flexible working hours and possibility of working from home,promoting a healthy work-life balance.

In line with our values , ETH Zurich encourages an inclusive culture. We promote equality of opportunity, value diversity and nurture a working and learning environment in which the rights and dignity of all our staff and students are respected.

Curious? So are we.

We look forwardto receiving your online application until August 15, 2025including:

• a CV
• a statement of research interest
• the names of two academic referees

The position staysopen until filled.Thepositionsarefunded for a total of three years, with the opportunity to extend the contract beyond the lifetime of the project.
