Missions

Observation data are collected within the scope of the ILICO Research Infrastructure observation networks as well as the range of European JERICO projects.
“ILICO”, the Coastal Ocean and Nearshore Observation French Research Infrastructure is dedicated to observing and improving our understanding of seashore environments and coastal ecosystems. ILICO is a distributed infrastructure comprised of 9 “in situ” observation networks and is the French node of the future Joint European Research Infrastructure of Coastal Observations (JERICO-RI).

The successful candidate will be expected to :
- Establish known and quantifiable uncertainties associated with the different observation systems (observations from fixed platforms, autonomous moving platforms, etc). S/he will determine which datasets will need the development of new methods for the uncertainty quantification.
- Propose and develop a statistical approach associating the “in situ” uncertainty to observation data combining:
- the “in situ” uncertainty linked to the instrument used (and defined by the metrological analysis)
- the uncertainty to observation data on the basis of complementary knowledge of the environment (i.e. concurrent / simultaneous observations, climatologies, numerical simulations, satellite observations).
The defined uncertainty will approach the representativity error which is essential for assimilating data into numerical models.
- Based on the assignment's outcomes, organize and contribute to a thematic workshop on the topic of “in situ” uncertainty involving French and European scientists from the community within the framework of the JERICO-S3 project. and ILICO,

Activities

- Collect information on acquisition methods regarding ILICO and JERICO data, analyse the different existing acquisition methods
- Estimate the uncertainty associated to measurements from the equipment used (ie sensors) and their deployment conditions
- Propose the guiding principles of a statistical method to estimate uncertainty associated to observation data in line with the constraints arising from the environmental variability and the deployment conditions
- Conceive a protocol to evaluate the robustness of the uncertainty estimate associated with different field measurement conditions
- Present & disseminate results
- Organise meetings with the community, including a workshop for the JERICO community

The work will be carried out in collaboration with actors from the “in situ” observation community as well as with experts from other domains as required (ie data assimilation, advanced statistics)

Skills

Technical skills and knowledge:
Required qualifications are related to:
Knowledge of coastal physical or biogeochemical oceanography
Knowledge of oceanic in situ observation systems
Skills / experience in data analysis and / or statistics and / or applied mathematics
Skills in evaluating uncertainty of measures and metrology

Personal qualities:
Ability to interact with researchers working on numerous and varied research topics.
Organisational skills
Communication skills and capacity to synthesise
Mastery of technical and conversational English

Work Context

For many years now, numerous “in situ” coastal observation data are collected by the networks comprising the ILICO (see below) research infrastructure as well as within the scope of the JERICO projects (see below). Together, these data meet different European data standards (in terms of harmonization of data collection practices and acquisition methods). Data are processed in order to reach the quality required for research uses.

Metrological analysis and other approaches evaluate the performance of automated systems deployed (i.e. assess sensor operations and identify dysfunctions). However, using the data collected in the coastal zone also requires an estimation of the associated uncertainty (measurement) – both in terms of the type of sensors used but also in terms of the deployment conditions and the inherent variability of the coastal environments sampled. The measurement uncertainty associated to coastal environment variability and constraints remains to be defined and quantified (launching this work comprises the overarching objective of this recruitment).

ILICO (www.ir-ilico.fr) Established in 2016, the Coastal Ocean and Nearshore Observation French Research Infrastructure (“ILICO”) is dedicated to observing and improving our understanding of seashore environments and coastal ecosystems. ILICO is a distributed infrastructure comprised of 9 “in situ” observation networks deploying a wide range of instruments to sample and measure parameters at high and / or low frequencies ensuring long term data collection on coastal dynamics, sea level evolution, physical and biogeochemical water properties, coastal water dynamics, phytoplankton and benthos composition and coral reef health in order to address a wide range of scientific questions.

ILICO RI is the French node of the future Joint European Research Infrastructure of Coastal Observations (JERICO-RI). JERICO-RI (www.jerico-ri.eu) is an integrated pan-European multidisciplinary and multiplatform Research Infrastructure (RI) dedicated to a holistic appraisal of coastal marine system changes.

Constraints and risks

The successful candidate would be preferably located in Plouzané (near Brest, France) within the LOPS laboratory. Another arrangement could be considered and part of the work may be carried out remotely depending on the evolution of the Covid-19 pandemic. Travel to partner laboratories or meeting venues (within France / Europe) may be required.
