Research Associate for the Project “BASS” Sub-Project 2.2, “Momentum and energy fluxes in the presence of surfactants” § 28 Subsection 3 HmbHG Institution: Faculty of Mathematics, Informatics and Natural Sciences, Department of Earth System Sciences, Institute of Oceanography Salary level: EGR. 13 TV-L Start date: 01.10.2024, fixed until 30.09.2026 (This is a fixed-term contract in accordance with Section 2 of the academic fixed-term labor contract act [Wissenschaftszeitvertragsgesetz, WissZeitVG]). Application deadline: 2024-07-31 Scope of work: part-time Weekly hours: 65 % of standard work hours per week Your responsibilities Duties include academic services in the project named above. Research associates may also pursue independent research and further academic qualifications. The research associate will investigate small-scale physical dynamics at the air-water interface and physics of wind-wave interactions, as 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 of BASS 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 are collaborating in joint laboratory and field campaigns, among which are dedicated experiments at Universität Hamburg’s wind-wave tank. BASS combines 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 specific goal of Subproject 2.2, “Momentum and energy fluxes in the presence of surfactants”, is to understand the complex, small-scale feedback mechanisms between wind, waves, and sea-surface monolayers, to allow improved analyses of other mechanisms driving fluxes and exchange processes across the SML. In order to achieve this goal, a unique, novel, wind-wave-surfactant measurement system has been developed for the wind-wave tank, with the ability of measuring simultaneously coupled air-water boundary layer dynamics, the evolution of millimeter-scale surface roughness features, and the influence of surfactants thereon. The system comprises a unique combination of state-of-the-art video, laser, digital imaging, and radar technologies, capable of being combined with a Particle Image Verlocimetry (PIV) system at the wind-wave tank and with other SML measurement systems of BASS partners, and having the potential to provide measurements in more complex conditions in a planned second phase of BASS. The successful applicant will actively participate in experimental campaigns at the University’s wind-wave tank facility, deploying video, laser, wire gauge, and radar sensors. She/he will finalize the design and construction of a state-of-the-art color imaging slope sensor, organize and perform its calibration, and perform wave measurements at a wide range of experimental conditions, including different wind speeds, mechanically generated waves, and surfactants of different concentration and visco-elastic properties. She/he will independently prepare, organize, and conduct dedicated experiments to meet the goals of Subproject 2.2, and will be responsible for the data analyses and the dissemination of the achieved results.
