Dear All,
Bellow please find a PhD Opportunity to work on GIC. I would appreciate if
you could disseminate it among any post-graduate student you might know to
be interested in it.
Thanks,
Miquel Torta
Pd. I apologise for any cross-posting

=======================================

*PhD Opportunity*

*Title of the topic           **Modelling and measuring geomagnetically
induced currents (GIC) and their sources in Iberia.*

*Host institution         **Observatori de l’Ebre - Ramon Llull University.*

*                                   Roquetes (Tarragona Province), Spain.*

*Advisors        *Dr. J. Miquel Torta (Observatori de l’Ebre-URL)

                      Dr. Santiago Marsal (Observatori de l’Ebre-URL)

*Financial Framework           **Ayudas para contratos predoctorales para
la formación de doctores 2018. Programa Estatal de Promoción del Talento y
su Empleabilidad en I+D+i. Subprograma Estatal de Formación.* Spanish
Ministry of Science.

●     *The call is expected to open in September and close in October 2018.*

●     The position is for a maximum of 4 years.

●     Expected annual gross salary: *16.420 €*.

●     The funding also includes the tuition fees for the doctoral studies
in the Observatori de l’Ebre (http://www.obsebre.es/en/phdprogram) and some
money for visiting other research centers.

●     The funds are linked to the *IBERGIC project*.

*Profile of applicant   *The candidate must have a M.Sc. or equivalent
degree in Physics, Geophysics, Civil Engineering or similar.

●     Experience in scientific programming with Matlab (or similar
analyzing programming languages, such as FORTRAN, Python or R).

●     Excellent communication skills, including writing, and the ability to
work in a team and individually with passion, dedication and integrity.

●     Good proficiency in the English language.

*Description of the topic       *The student will work to achieve the
following objectives:

●     Spatio-temporal characterization of the sudden commencements of
geomagnetic storms. To advance in the understanding of the morphology and
temporal evolution of electrical current systems both in the near-Earth
space and in the upper atmosphere that generate severe geomagnetic sudden
commencements (SC).

●     Development of a methodology for the indirect measurement of GIC. It
will be based on the monitoring of the magnetic field generated under
certain power transmission lines previously chosen, which may be validated
by the measurements made in the neutrals of transformers in the nearby
substations.

●     Improvement of the modelling of GIC by integrating the geophysical
models and the power grid models. The purpose is to obtain vulnerability
maps of the power grid considering different scenarios and to identify
critical aspects in the infrastructure.

*Description of the project   **Holistic characterization of GIC in the
Iberian peninsula: from the analysis of magnetospheric and ionospheric
currents to the influence of the lithosphere (IBERGIC) CGL2017-82169-C2-1-R*

By means of a multidisciplinary approach, this project aims at addressing
the characterization, in the Iberian Peninsula, of one of the main ground
effects of space weather on Earth: that derived from what are known as
geomagnetically induced currents or GIC. These currents are produced in
long terrestrial conductors as a result of geomagnetic storms, and may
affect pipelines, railways and power supply, the critical infrastructure
from which society has become more dependent. The main challenge of the
proposal is to analyze and characterize the magnetosphere-ionosphere-earth
electromagnetic coupling and to improve the accuracy of the vulnerability
map of the Spanish high voltage power transmission network in front of the
GIC. To do this, i) we will characterize the magnetospheric and ionospheric
sources that generate the greatest GIC and how they are related to coronal
mass ejections and solar flares, as well as the solar wind velocity, the
incidence angle and the local time when the compression
magneto-hydrodynamic wave reaches the Earth; ii) a geoelectric model will
be determined on a lithospheric scale in the Iberian Peninsula to predict
how the 3D structure of subsurface resistivity and network topology affect
GIC; and iii) GIC intensities at critical locations will be obtained in a
non-invasive manner, i. e., without interfering with the operations of the
network or power plants. Improving GIC estimation by integrating
geophysical models and transmission grid models will enable accurate
mapping of geoelectric field variations and vulnerability maps of the power
grid. These maps will allow the power grid operators to design strategies
of resilience and mitigation of impacts considering different scenarios and
also to identify critical aspects in the infrastructure, with the
corresponding economic and social benefit at national level. The 3D model
of electrical resistivity of Iberia, which will be obtained by integrating
previous magnetotelluric soundings and new data through the surveys planned
in this project, will be the first reference map, will serve as a basis for
subsequent geophysical studies and will be an indispensable contribution
for all international projects in this area. Finally, the contribution to
the knowledge of this natural hazard, as well as its diffusion to the
society, will generate a real and founded perception of its vulnerability
and will allow taking the appropriate measures on a founded basis.

*Application    *In order to apply, the student will have to fill the forms
in electronic form and provide:

●     Copy of the passport (for foreign students who do not reside in
Spain).

●     Curriculum Vitae (in the appropriate format)

●     Academic certificate showing the marks obtained for each subject and
the dates in which the subjects were passed.

*More details will be published when the call opens in September 2018.*
*Contact          *For any enquiry, please contact Dr. J. Miquel Torta (
jmtorta en obsebre.es) or Dr. Santiago Marsal (smarsal en obsebre.es) adding
IBERGIC-FPI to the subject line.
