Over the past decades, the multi-beam echo-sounder (MBES) has become an important imaging tool in offshore survey operations. Its main application is to map the depths of the ocean floors from the two-way travel times. The potential of the MBES is much larger, however, as the levels of the MBES signals contain important information regarding the type of sediment at which the sound is scattered. The ANCE research group has developed a number of methods that use these so-called backscatter values for classifying the surficial sediments.
Within the project described here, the focus will be on mapping the occurrence of marine benthos such as shell beds, since this is becoming a required element in regulations aiming at sustainable use of our oceanic environment. Recent developments have equipped acoustic multi-beam echo-sounder (MBES) imaging systems with capabilities to take multi-spectral data, i.e., almost co-located acoustic measurements over a range of frequencies. As a postdoc (4 years) you will be responsible for designing and executing sea-going campaigns. In addition you will add to the development of data analysis techniques that combine all data streams from these multi-spectral data to realize acoustic classification techniques that map the occurrence of aggregations of specific marine benthos. Ensuring documentation of the developed algorithms in measurement protocols is also part of the job. The project will be carried out in cooperation with a number of companies and governmental organizations.
This postdoc position will be hosted in the Aircraft Noise and Climate Effects Section of the Department of Control and Operations of the Faculty of Aerospace Engineering. The mission of the Department of Control and Operations is to improve the safety and efficiency of operations in aerospace and to reduce the impact on the environment. The department comprises three sections: Control and Simulation, Air Transport Operations and the Aircraft Noise and Climate Effects (ANCE) section.
ANCE focuses on modelling the effects of aviation on the environment in terms of noise and emissions. The noise research also deals with acoustic measurements. ANCE expertise in this area is directed towards the development of acoustic arrays for imaging aircraft noise using innovative beamforming techniques. In addition, as a spin-off, ANCE is also internationally recognised for its expertise in the field of underwater imaging, e.g. for offshore applications.
The candidate should have an MSc and PhD degree in an area relevant to the subject, e.g. (applied) physics, oceanography, earth sciences, marine biology, mechanical engineering and civil engineering. A combination of good mathematical/analytical skills and strong programming skills are required. Experience with seagoing campaigns is advantageous for this position. The candidate should have a very good command of the English language, in direct communication as well as writing skills.
Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities. The TU Delft offers a customisable compensation package, a discount on health insurance and sport memberships, and a monthly work costs contribution. Flexible work schedules can be arranged.
For international applicants we offer the Coming to Delft Service and Partner Career Advice to assist you with your relocation. An International Children's Centre offers childcare and there is an international primary school.
For questions, please contact Prof. M. Snellen, Section Aircraft Noise and Climate Effects, Email: M.Snellen@tudelft.nl
The application should include a detailed CV, 2 reference contacts, proof of English language level and copies of your BSc and MSc degrees and transcripts, along with a motivation letter by 30 April 2021.
If your MSc diploma and transcript are not in Dutch or English and you will be the selected candidate, the TU Delft will ask you to deliver a certified translation.
