Job description

Helmholtz-Zentrum Hereon
The Helmholtz-Zentrum Hereon conducts cutting-edge international research for a changing world: Around 1,100 employees contribute to the tackling of climate change, the sustainable use of the world’s coastal systems and the resource-compatible enhancement of the quality of life. From fundamental research to practical applications, the interdisciplinary research spectrum covers a unique range.

Institute of Coastal Ocean Dynamics
The Institute of Coastal Ocean Dynamics at the Hereon develops innovative technologies, investigates the physical and biogeochemical processes of the coastal ocean and the impact of anthropogenic influences on the natural state. It is located near Hamburg.

Ph.D. Position in the area of Air Sea Fluxes

Reference code: 50085483_2 – 2022/KD 1
Commencement date: October 1st, 2022
Work location: Geesthacht (near Hamburg)
Application deadline: September 11th, 2022

We are looking for a highly motivated Ph.D. candidate to investigate the interactions between wind, waves, and sea-surface monolayers. Understanding energy and scalar fluxes across the air-sea interface is crucial for a number of environmental challenges, including weather, climate and sea state forecasting. The Air-Sea Fluxes group at the Institute of Coastal Ocean Dynamics conducts laboratory- and field-based research, by developing and deploying unique, novel high-resolution imaging systems to investigate submillimeter-scale turbulent dynamics in multiphase environments such as the ocean surface.

The project is part of the research group “Biogeochemical processes and Air-sea exchange in the Sea-Surface microlayer (BASS)” funded by the German Research Foundation. The overall goal is to investigate the importance of the sea-surface microlayer (SML) as a biogeo- and photochemical reactor, and how its reactivity affects ocean-atmosphere interactions. Eight subprojects will collaborate in joint field campaigns in the open North Sea, in a joint mesocosm study at the Sea-Surface Facility of the University of Oldenburg, and in joint experiments at University of Hamburg’s Wind-Wave Facility. BASS will combine interdisciplinary expertise, advanced technologies for millimeter-scale observations, core infrastructures for controlled experiments, and state-of-the-art analytical facilities at the molecular levels.

The candidate will develop and use novel imaging techniques at University of Hamburg’s large wind-wave facility, to quantify, understand and parametrize wind-wave-surfactant interactions, and their effect on air-water fluxes of momentum and scalars.

We invite applications for a Ph.D. position in the area of Air Sea Fluxes at the Institute of Coastal Ocean Dynamics with preferred starting date October 1st, 2022. The position is limited to March 31st, 2026.

Equality of opportunity is an important part of our personnel policy. We would therefore strongly encourage qualified women to apply for the position.

Your tasks
  • designing, planning and performing laboratory (wind-wave facility) experiments, using state-of-the-art imaging techniques
  • developing computational codes to process and understand large experimental datasets (e.g., image processing)
  • analyzing experimental results; developing conceptual models and parameterizations
  • scientific publication and presentation
  • working as an integral part of a motivated multidisciplinary team within the institute and with external academic partners

For further questions please contact Dr. Marc Buckley (

  • extensive options of vocational training (i. a. expert seminars, language courses or leadership seminars)
  • flexible working hours and various models to ensure the compatibility of family and career
  • excellent infrastructure, including a scientific in-house library as well as modern work spaces
  • remuneration according to the standards of the collective wage agreement TV-AVH including further social benefits
  • free employee advice – Employee Assistance Program (EAP)
  • childcare offers
  • Welcome Office, guest accommodation
  • PhD Buddy Program
  • canteen at the Geesthacht location

Severely disabled persons and those equaling severely disabled persons who are equally suitable for the position will be considered preferentially within the framework of legal requirements.


Then we are looking forward to receiving your comprehensive application documents (cover letter, CV, transcripts, certificates etc.) indicating the reference number 2022/KD 1 until September 11th, 2022.
