PhD Research Fellow in Acoustics (Fiberoptic Distributed Acoustic Sensing)
There is a vacancy for a PhD Research Fellow in acoustics at the Department of Physics and Technology (IFT) at the University of Bergen (UiB). The position is for a fixed-term period of 4 years, with employment from 1 September 2023.
The position is subject to financing by UiB grant under the Smart Ocean Centre for Research-based Innovation, hosted by UiB.
We offer an opportunity to join one of the leading research and innovation clusters within marine instrumentation and operations, in an exciting time for marine life, environment, and observation technologies. In a consortium counting about 20 research, industry and public partners, the Smart Ocean Centre focuses on flexible and cost-effective solutions for monitoring and management of a productive and healthy ocean.
The PhD candidate will be affiliated with the Acoustics Research group at UiB/IFT, addressing cutting-edge research in experimental, theoretical, and numerical acoustics, currently making up a group of 19 people (permanent employees and emeriti, postdoctoral fellow, PhD and master students). The group focuses on fundamental research and collaborates with external partners on applications, with interests spanning a broad range of areas (including guided ultrasonic waves, ultrasonic fiscal flow measurement of oil and gas, marine/fisheries acoustics, distributed acoustic sensing, and material/fluid characterization). The group is closely linked to two Centres for Research-based Innovation, SFI Smart Ocean – Technology for Monitoring and Management of a Healthy and Productive Ocean; and SFI CRIMAC – Marine Acoustic Abundance Estimation and Backscatter Classification.
About the project/work tasks:
The PhD project is part of the Smart Ocean Centre. The overall aim of the Centre is to create a wireless observation system for multi-parameter monitoring of underwater environments and installations, based on a flexible and autonomous smart sensor network.
In contrast to electromagnetic and optical waves, acoustic waves travel great distances underwater, and therefore acoustic sensor technology forms the basis for many remote sensing systems designed for monitoring ocean man-made sources and marine creatures. As such acoustic sensor systems can satisfy a range of ocean monitoring applications, from monitoring the integrity of offshore wind farms and other industrial subsea installations, as well as in monitoring shipping traffic, the influence of ocean noise on animal behaviour, and climate studies.
In recent years, Distributed Acoustic Sensing (DAS) has emerged as a technology for making spatially resolved measurements of acoustic disturbances using fibre optics. In addition to facilitating acoustic measurements over large length scales, DAS is particularly interesting for ocean applications because it can utilize the same ubiquitous optical fibres found on the ocean floor, and on installations.
The PhD candidate will work on the development and understanding of fibre optic DAS technologies for novel ocean applications. An important element will be how to use and get value out of existing fibre optical infrastructures used for different purposes (e.g., subsea communication cable networks). The project will cover aspects including development and operation of NORCE’s Optoelectronic DAS hardware, as well as the development of data processing techniques for interpreting the large data streams (~1 GB/s). In addition to working with real-world DAS data, the project will utilize small scale experiments in combination with mathematical and numerical modelling. These activities will contribute to improved fundamental understanding of the physical mechanisms involved in fibre-optic detection of acoustic signals from different ocean sources. The candidate will develop cutting edge sensing technology that will help ocean industries to operate in a safe and efficient way, and at the same time provides valuable knowledge about the marine environment that helps authorities set appropriate regulations for sustainable operations.
The PhD work is to be carried out in cooperation with Centre partners, co-supervised by NORCE and Tampnet. The candidate is expected to participate in the guidance of master students.
Qualifications and personal qualities:
- Applicants must hold a master’s degree or equivalent education in physics or equivalent discipline. Master students can apply provided they complete their final master exam by 20.06.2023. It is a condition of employment that the master’s degree has been awarded.
- Good skills in measurement physics laboratory/field work involving acquisition and processing of electronic signals, is a requirement.
- Good programming skills is a requirement, e.g., using Matlab, Python, LabVIEW.
- Applicants must be able to work independently and in a structured manner and demonstrate good collaborative skills.
- Applicants must be proficient in both written and oral English.
Experience from one or several of the following areas is an advantage:

- Good knowledge of acoustic laboratory and/or field measurements.
- Good skills in numerical modelling within acoustics.
- Good knowledge of optoelectronic systems and sensors, particularly distributed sensor systems.
- Experience from finite-element modelling of acoustic wave propagation in solid and fluid media (programming, use, or both), e.g., using COMSOL Multiphysics.
- Experience from mathematical-numerical modelling of acoustic waveguide propagation in solid-fluid media (e.g., layered solid-fluid media, or guided acoustic/ultrasonic waves).
- Experience from modelling and data analysis related to Distributed Acoustic Sensing (DAS).
- Good knowledge of digital signal processing.
- Good command of the Norwegian language.
Personal and relational qualities will be emphasized. Ambitions and potential will also count when evaluating the candidates.
