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.


  • PhD position "The historical ocean carbon sink and the role of ventilation" (M/F/d)


This position will be part of the ERC starting grant project OceanPeak: The global ocean carbon cycle after peak emissions, dynamics and process attribution in a seamless model from coastal shelves to the open ocean.

The ERC group, led by Dr.

Judith Hauck, is located in the Marine Biogeosciences section at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research.


Background:


The ocean carbon sink estimate based on global ocean biogeochemistry models in the Global Carbon Budget shows a substantial spread, with the range of all models being larger than the European Union's current fossil CO2 emissions.

Prime suspects for biases in ocean carbon cycle models are formulations of ventilation processes that are responsible for the transfer of carbon out of the surface mixed layer and into the ocean interior (deep ocean).

This encompasses mixing schemes and parameterizations of small-scale processes (meso

The preferred starting date is spring/summer 2023.


Tasks

  • Develop a new set of evaluation metrics for the modelled open ocean carbon cycle based on emerging data from biogeochemical Argo floats that target the vertical gradient of carbonrelated variables (e.g. pH, derived pCO2, nutrients, oxygen).
  • Optimize the ocean carbon cycle model FESOM-REcoM in order to reduce mismatch between observed and modelled gradients across the base of the mixed layer, with the help of the newly developed metrics.
  • Quantify the evolution of the global open ocean carbon sink in the optimized model, including on the rate of change of the ocean carbon sink since 2000, which differs by a factor of three between the current Global Carbon Budget model ensemble and observationbased estimates.

Requirements:


  • Master degree in oceanography, marine sciences, physics, geosciences, climate sciences or related field
  • Basic knowledge of at least one of the themes: ocean carbon cycle, ocean ventilation, ocean circulation models, ocean biogeochemistry models
  • Skills in processing, statistical analysis and visualization of data
  • Strong English language skills
  • Ability to work focused, independently and cooperatively in a team

Advantageous

  • Experience in ocean biogeochemical modelling (conduct simulations, and/or analyse model results)
