Scientist with a Focus On Biogeochemical Modelling - Bremerhaven, Deutschland - Alfred-Wegener-Institut für Polar- und Meeresforschung
vor 1 Monat
Beschreibung
The Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) is a member of the Helmholtz Association (HGF) and funded by federal and state government.
AWI focuses on polar and marine research in a variety of disciplines such as biology, oceanography, geology, geochemistry and geophysics thus allowing multidisciplinary approaches to scientific goals.
- Scientist with a focus on Biogeochemical modelling (M/F/d)
Background
The position is part of the CDRmare research mission within the sea4soCiety blue carbon consortium.
The aim of this one year position is to expand the existing model UVic ESM to assess the potential of the free floating sargassum for Carbon Dioxide Removal.
Using literature values and measured carbon and nutrient uptake and remineralization rates of Sargassum under different environmental conditions, you will modify the parameterization of an existing marine biogeochemical model that includes large-scale offshore macroalgae mariculture (Wu et al., 2023) and is embedded in an Earth system model of intermediate complexity, UVic (Mengis et al., 2020; Keller et al., You will conduct historical, present-day, and future climate change scenario simulations(high and low climate change), where Sargassum sinking is artificially enhanced before reaching the Caribbean coast, to estimate the carbon uptake of floating Sargassum.
You will investigate the fate of sunken biomass by varying the rates at which it is remineralized, (i.e., a sensitivity analysis to evaluate uncertainties that result from limited information on Sargassum remineralization rates).
Overall, these simulations will provide a first indication for the feasibility and effectiveness of enhanced sinking of Sargassum for marine CDR.
Tasks
- Modify the parameterization of an existing marine biogeochemical model that includes largescale offshore macroalgae mariculture (Wu et al., 2023)

Requirements:
- MSc or PhD in biogeochemical modelling
- Experience of more than 2 years working with biogeochemical earth system models such as UVic
- Strong interest in understanding the carbon dioxide removal potential of macroalgae.
- Expertise in coding
- Knowledge of carbon and nutrient cycling in the ocean
- Experience in data analysis and excellent computer skills
- High interest in collaborative research, presentation and publication of scientific data
- Very good English language skills written and spoken
- Capacity for teamwork, international, inter
