Post Doctoral Fellowships, underwater noise disturbance to bowhead whale

University of Victoria

 

Location: Victoria, British Columbia, Canada

Post Doctoral Fellowships, underwater noise disturbance to bowhead whale

We are seeking two highly qualified candidates for post doctoral fellowships to work on a large collaborative project focused on underwater noise disturbance to bowhead whales (Balaena mysticetus) in the Canadian Arctic. The candidates would work closely with Dr. Stephen Insley and Dr. William Halliday with Wildlife Conservation Society (WCS) Canada (www.arcticnoise.ca) and Dr. Francis Juanes at the University of Victoria (www.juaneslab.weebly.com), and would be based in the Department of Biology at the University of Victoria in Victoria, British Columbia, Canada. These fellowships will focus on three main tasks: 1) bioacoustic analyses of large passive acoustic monitoring datasets to examine spatial and temporal trends in the presence of bowhead whales and other marine animals, as well as documenting underwater noise from ships; 2) examining the reaction of bowhead whales to ships and underwater noise from ships using satellite telemetry data and possibly acoustic tags; 3) examining the current noise exposure to bowhead whales by combining acoustic propagation modeling with ship tracking data, and then examining mitigation strategies for reducing noise exposure to bowhead whales. The exact tasks assigned to each post doc will depend on the pool of applicants.

The first position will start in September 2019 for a fully funded fellowship funded through WCS Canada. The second fellowship will start in June 2020, and will be funded through a Mitacs Elevate Post Doctoral Fellowship (https://www.mitacs.ca/en/programs/elevate), with Dr. Juanes at the University of Victoria as the academic supervisor and WCS Canada as the partner organization. Both positions will come with health benefits.
The successful candidates must have a strong background in some combination of the following essential skills: bioacoustic analyses of passive acoustic monitoring data; acoustic propagation modeling; and spatial analyses of animal movement data. All candidates should have a strong background in statistical analyses of large datasets. The majority of time will be spent analyzing data, but may also include 2-4 weeks of field work per year in the Canadian Arctic to retrieve and deploy acoustic recorders or deploy acoustic tags on bowhead whales. The following experience will also be considered an asset: working in remote locations; working out of a small boat; working with or communicating research to Indigenous communities. The successful candidate must hold a PhD by the start date of this fellowship, and should have a strong record of scholarly publications. Interested candidates should send a cover letter, CV, and names and email addresses of two references to Dr. William Halliday (whalliday@wcs.org). This application will remain open until the right candidate is found for both positions. Only applicants who have been selected for an interview will be contacted.

Required Qualifications for both positions

Candidatures will be processed starting 17-July-2019 and evaluated as received until the position is filled.
Details also available at http://www.lam.jussieu.fr/Stages/index.php?page=These_FSP
In the context of the collaborative project EVAA, the EVAA_Ver project unites the following team members to provide a PhD funding opportunity (2019-2022):
Labo ETIS – U. de Cergy Pontoise
Institut Jean Le Rond ∂’Alembert
CRC – Equipe Conservation et recherche du Musée de la musique – Cité de la musique – Philharmonie de Paris
Centre de recherche du château de Versailles

Subject
Experimental Virtual Archeological-Acoustics: Multimodal study of the influence of rooms on the playing techniques of musicians on instruments of the 17th and 18th century at Versailles

Keywords
Virtual acoustics, virtual reality, room acoustics, psychoacoustics, musical acoustic, historically informed performance, musicology, Baroque period, Chateau de Versailles

Thesis topic
The PhD project consists of assisting in the creation of a real-time room acoustic simulator for use with musicians, taking into account the musicians movements and the impact of dynamic source directivity. The simulator will be put into use for studying the impact of room acoustics on musicians playing, focusing on comparisons between Baroque chamber music venues and classical period equivalents (Berlioz time). The thesis work will contribute to the research and documentation of pertinent venues, acoustic measurements of existing venues, and the creation of ecologically valid geometrical acoustics models of some of these venues. The thesis will include a series of perceptual studies examining the impact of acoustic variations on playing, in the context of historically informed performance methods.

Context
Research in the history of music and musical acoustics has led to what is known today as a historically informed performance (HIP) using period instruments. Historically informed performance consists of an ideal match between musical instrument, repertoire, and playing techniques. However, for the moment, little research has been carried out on the interaction between the musician and the performance space from an acoustic point of view. Thanks to real-time acoustic simulations of historic rooms, the project proposes to include this dimension in the historically informed performance. By positioning the musician, who plays on accurate facsimile of historical instruments, in virtual play spaces, the influence of the sound and visual environment on the musical practice can be studied. One of the innovative aspects of this thesis subject is to couple a real-time acoustic simulator with a visual room simulator providing musicians with an immersive audio-visual experience. This tool, beyond understanding baroque and classical musical practices will also help to understand the technical evolutions of instruments of the corpus selected in relation to the evolution of the concert halls.
The EVAA_Ver project will build on the results obtained in the VERSPERA project (Digitization and Modeling of Versailles Plans under the Ancien Regime), funded by the Heritage Science Foundation and the Ministry of Culture. The software developed by ETIS as part of the VERSPERA project makes it possible to rapidly build a 3D visual model of the spaces represented by digitized plans, complimented by graphic design students from the “Heritage, visualization and 3D modeling” program, for a precise and photo-realistic 3D model of spaces that are now missing or modified.
The project EVAA_Ver will extend VERSPERA by adding the dimension of sound. By associating musicians, acousticians, historians, and computer scientists, EVAA_Ver strives to federate around the same cultural heritage object a diverse and complementary collection of scientific disciplines. Exploring different disciplinary fields, the results of EVAA_Ver and the overall EVAA umbrella project can nourish each other.Thesis topic
