This project will quantify energy dissipation and air entrainment of individual short-crested breaking waver waves to provide better constraints on bubble-mediated fluxes of gas, mass and energy across the air-sea interface.
As a Research Associate, you will work in the Fluid Mechanics Section of the Civil and Environmental Engineering department and the work will consist of laboratory, field and modelling components.
In the laboratory component you will develop a novel underwater imaging system to quantify air entrainment rates in laboratory short-crested breaking water waves in Imperial College’s world-class hydrodynamics laboratory.
For the field component you will work with Project Partner Dr. Benetazzo at the Italian Institute of Marine Sciences (ISMAR) and an Imperial College PhD student to interpret data derived from digital sea surface images of breaking waves acquired from the Acqua Alta oceanographic tower in the Adriatic Sea.
For the modelling component you will use the results from the laboratory and field components to assess wave breaking energy dissipation parameterisations in a spectral wave model working together with Project Partner Dr. Bidlot at the European Centre for Medium Range Forecasts (ECMWF).
Output from the wave model will then be used to calculate bubble-mediated fluxes of gas.
Duties and responsibilities
You will be responsible for developing a novel underwater imaging system to measure bubbles beneath actively breaking waves in the laboratory.
This will involve sourcing specialised camera and lighting equipment, designing and assembling the imaging acquisition system and developing bespoke image processing routines.
You will use these laboratory-derived results with measurements of oceanic breaking waves from a stereovision camera system to develop statistical descriptions of energy dissipation and air entrainment rates of breaking waves in the field.
Your work in the project will culminate with exploring global patterns of breaking wave energy dissipation and air-sea exchange of using outputs from a state-of-the-art spectral wave model.
In addition to specific tasks of the project, you will contribute to the supervision of PhD, MSc and undergraduate students in the research group.
- PhD (or equivalent) in Oceanography, Fluid Mechanics, Mathematics, Computer Vision, Physics or a closely related discipline.
- Ability to setup and execute high quality and bespoke laboratory experiments.
- Experience with digital image acquisition and/or digital image analysis.
- A strong desire to learn more about breaking waves, energy dissipation, bubbles and air-sea interaction.
Informal enquiries are strongly encouraged and should be directed to Dr Adrian Callaghan. In addition to submitting the online application, please send a CV and examples of your work that are relevant to the application.
Any queries regarding the application process should be directed to Briony Webb at firstname.lastname@example.org.
Candidates who have not yet been officially awarded their PhD can be appointed as a Research Assistant within the salary range £36,045 - £39,183 per annum.
