The impact of whaling in the last century and recent environmental changes are major issues for the
conservation of blue whale populations in the Southern Ocean. Until the implementation of a total
whaling ban in 1982, it is for instance estimated that more than 99% of the Antarctic blue whale
population was decimated in the Southern Ocean. An international initiative is underway to coordinate
their study in the Southern Ocean to provide recommendations for their conservation, based on solid
The recovery of large-whale populations in the Southern and Indian oceans is still poorly
known due to the sparseness of information, such as visual observation, in such remote areas with
prevailing rough weather conditions. However, blue whales are acoustically very active and can easily be
detected and their species and sub-species deciphered from their specific calls. Passive listening of the
high acoustic-activity of blue whales provides an alternative approach, very efficient and non-intrusive to
monitor their status in terms of presence, distribution, migration pattern, and sympatry.
In this context, an acoustic observatory has been set up in the southern Indian Ocean in 2010. We have
now collected up to 7 years of continuous recordings at 5 to 6 sites spanning a wide range of latitudes and
longitudes (30 ̊ x 30 ̊). An initial thesis (2014-17) demonstrated the wealth of information in these data to
study the Antarctic Blue whale (Leroy et al., 2016). Here we propose to extend to other species, sub-
species and sub-populations of blue whales (pygmy blue whale, fin whale) the developed approach: tests
of new detection algorithms, systematic analysis of available data, characterization and classification of
whale calls. The results will be interpreted in terms of seasonal presence, geographic distribution,
sympatry and use of habitats in the southern Indian Ocean. This observation will then be examined in view
of the evolution of environmental conditions (temperature, trophic chain, movements of oceanic front,
ambient noise, ...).
This pluridisciplinary project covers the domains of hydroacoustics, signal processing and marine ecology.
The project involves a large amount of processing and analysis of acoustic signals from a large data base.
This work will benefit from data collected in the framework of the Observatory at IUEM, environmental
data and data from the hydroacoustic observatory of the seismicity and biodiversity in the Indian Ocean
Expected candidate profile
In addition to an interest in hydroacoustics and marine ecology, this project requires a solid background
and experience in signal processing and managing large digital database.
National and international collaboration
This work will be conducted in interaction with the LabSTICC-Telecom Bretagne, the Applied Physics
Laboratory, University of Washington, Seattle WA (USA) and the Woods Hole Oceanographic Institute
(WHOI, USA). Outputs from this thesis will contribute to the « Southern Ocean Research Program » (SORP)
from the International Whale Commission.

For the purpose of underwater mine countermeasure, automatic (underwater) target recognition (ATR) is
usually performed on high resolution sonar images. However, environmental effects are known to degrade
performances of most of the existing ATR processes. Up to now, these effects are usually limited by filtering
the image but it must be noticed that this strategy is not relevant for some environmental conditions and can
also alter the available information [1, 2, 3].
In this thesis, on the contrary, we consider the environment as an important piece of information that can be
used to design a robust ATR process. The challenge is to process sidescan sonar images to represent and to
quantify information of the seafloor nearby a target in order to help the detection and the recognition stages.
Previous works at ENSTA Bretagne consisted in describing the seafloor by the use of a new mathematical
operator: the monogenic signal . Combined with the intrinsic dimensions in a multi-scale framework, this
operator allows to characterize the seafloor in terms of energetic and geometrical properties at several levels
of details .
Following the above mentioned works on seafloor characterization, the candidate will have to analyze and
then to include this information in the ATR process so as to improve ATR performances.
Analysis means understanding, processing and evaluating the available mathematical tools developed in an
ongoing PhD thesis [6, 7, 8]. The recently proposed classification of seafloor as homogeneous, anisotropic and
complex will be assessed and discussed. It would help the candidate to build a robust ATR process. Whereas
the standard ATR process is sequential and likely to propagate errors, the candidate will have to propose a
new adjustable framework in which environment properties can be set as inputs for adjusting the target
Conditions of Application
The candidate should have a strong background in mathematics, information theory, and signal processing.
To apply, please send an email to email@example.com giving motivations for the topic, a
full CV, student’s university transcripts, recommendation letters or contacts of former teachers/supervisors,
MSc project or thesis report (if available).
Considering Defense restrictions, the candidate has to be an EU national.

18 months Postdoc Position in the context of the BBC Cominlabs Project.
The objective of the project is mainly to explore Network on Chip (NoC) hybrid technologies to take advantage of broadcast mechanisms within manycore architectures. The originality of the project firstly relies in the combination of 3 technologies (Radio, Wired, Optical links) that all have different benefits and drawbacks and can be used efficiently within a single NoC to transmit different types of data and synchronisation messages.
The work will first consist in the design of SystemC NoC simulator that will abstract the different technology layers with different access protocols as well as timing and power models. Secondly it will be necessary to add new communication mechanisms that cannot be detailed here. The last point concerns the interface with multiprocessor simulators.
A strong background in SystemC and parallel computing is required. A good knowledge of NoC tools and techniques will be highly appreciated.
The successful candidate will join the MoCS team in Lorient. The fellowship is awarded for a period of 18months starting in June or September 2017.
Interested candidats are expected to send, by email to jean-philippe.diguet(at)univ-ubs.fr, a detailed academic CV and references such as contact information of former supervisors.
