3) Goldschmidt2017 Conference, Paris, August 13 – 18:
Abstracts can be submitted online until April 1st, 2017 at https://goldschmidt.info/2017/abstracts.
--session 07c: Hydration and Dehydration of Materials on Earth and Other Bodies of the Solar System
Conveners: Agnès Elmaleh, Hongwu Xu
Keynote speaker: Toshimori Sekine (University of Hiroshima, Japan)
Fluxes of water within and between large and small bodies of the solar system are driven by small scale processes involving the interaction between aqueous fluids and minerals. Implications of such processes include the budget of volatiles and the geo(-bio)chemical cycles of water soluble and redox sensitive species. Basic properties such as the volatility of water and its affinity for the different compartments of a planet or a small body depend on the crystal-chemistry, stability and kinetics of formation of hydrated phases. Contributions from experimental, modelling and analytical studies, down to the nano-scale, of the processes of hydration and dehydration of solids on Earth and other bodies of the solar system, during alteration, metasomatism or high pressure processes, including shock dehydration, are welcome.
-- Session 2c: Heterogeneous Moon: Endogenous and Exogenous Processes in Lunar Evolution
The aim of this session is to combine lunar geochemistry, geochronology, geophysics, and impact cratering on the Moon. Linking chemical and physical models for the lunar evolution to temporal constraints allows defining times and rates for its evolution. The Moon probably formed due to a giant impact onto the proto-Earth. It is a differentiated body composed of geochemically distinct crust, mantle, and core. Mantle dynamic processes affected the global and regional chemical evolution of the crust and mantle structures mostly preserved to the present day. The Moon´s mineralogical and chemical surface maps are the proto-type records for global magma ocean concepts showing that it crystallized and differentiated probably over millions to hundreds of millions of years. The thermal evolution and cooling were modified/delayed due to the exposure to the early Solar System bombardment. We invite studies on the chemical and thermal evolution of the Moon from geochemical and geophysical models and sample analyses in an effort to converge efforts for an interdisciplinary approach to the research. Processes such as impact cratering not only caused chemical heterogeneities but also modified the surface morphology. The lunar cratering record is used as a scaled template for other planetary bodies in the Solar System, however there are several interpretations; hence contributions to challenge the current calibration of the lunar cratering rate are welcome.
4) offre de thèse financée sur "développement d'outils algorithmiques pour l'exploitation de spectres de masse `a très haute résolution", IPAG, Grenoble
Contexte :
Les comètes et les astéroïdes contiennent de la matière organique qui s'est formée très tôt dans l'histoire du Système Solaire puis a évolué chimiquement par irradiation, et par altération aqueuse et thermique. Cette matière organique s'est déposée à la surface des planètes et pourrait constituer une source de précurseurs pour l'émergence de la vie sur la Terre primitive. Des résidus organiques sont synthétisés au laboratoire dans des conditions reproduisant les environnements astrophysiques puis sont analysés par différentes techniques analytiques. Ces analogues sont comparés à la matière organique des objets interplanétaires (comètes, astéroïdes, météorites) afin de contraindre l'évolution physique et chimique de ces objets et raffiner les scénarios de formation et d'évolution de la matière organique dans le Système Solaire.
Objectifs :
La thèse s'inscrit dans un projet ANR qui consiste à mettre en place un système de chromatographie liquide couplé à un spectromètre de masse de type Orbitrap. Les protocoles d'acquisition pour des analogues de résidus de matière organique seront développés en collaboration avec G. Danger (PIIM, Marseille) et C. Geffroy-Rodier (IC2MP, Poitiers). Nous rechercherons particulièrement des molécules telles que les acides aminés, aldéhydes et sucres. A terme, les même protocoles seront appliqués à de la matière organique extraite d'échantillons extraterrestres. Les spectres seront analysés à l'aide du programme Attributor développé à l'IPAG spécialement pour l'analyse et l'interprétation de données de spectrométrie de masse à très haute résolution. Le doctorant sera en charge de l'implémentation des outils nécessaires à la réduction des données et à l'exploitation scientifique des spectres de chromatographie liquide obtenus. Ces outils seront mis à la disposition de nos collaborateurs à Marseille et Poitiers. Le doctorant sera également appelé à développer des outils algorithmiques, notamment de traitement du signal, nécessaires à l'exploitation du prototype Cosmorbitrap en développement au LPC2E à Orléans.
Mots-clefs:
Exobiologie, matière organique, chromatographie en phase liquide, spectrométrie de masse, traitement du signal.

5) workshop "Chondrules as Astrophysical Objects", Vancouver, May 9-11
I am writing to personally encourage you to attend Chondrules as Astrophysical Objects or to distribute this email to colleagues of yours who might be interested in attending. I know some of you already pre-registered -- thank you! -- so please excuse me if you have received multiple reminders this week.
WHEN: May 9-11, 2017
WHERE: The University of British Columbia in Vancouver, BC.
ABSTRACT DEADLINE: February 28
REGULAR REGISTRATION DEADLINE: March 17
The motivation for the conference is summarized on the Web site (chondrules.phas.ubc.ca). Here is an abridged version: How can meteoritics and observations of planetary systems, including discs and debris, be used to inform general planet formation theory? This conference seeks to address this question by inviting meteoriticists, cosmochemists, and astronomers to explore how astrophysical observations can constrain chondrule formation models and how chondrules can help us put astrophysical observations in context. Examples of questions we aim to address are:
How might chondrules be related to “pebble accretion”?
What are the observational signatures of exochondrules?
What role do chondrules and exochondrules play in planet formation?
What cosmochemical and spectral signatures of chondrules could be common for exochondrules?
As part of the Peter Wall Institute for Advanced Study at UBC, we also aim to explore intersections between art and science, with attention to data transformation and science dissemination. We encourage participants to submit posters and contributed talks on this subject as standalone contributions or in addition to science contributions.
The Web site is once again here: chondrule.phas.ubc.ca
Abstract submission (also linked via the Web site) is here: http://www.hou.usra.edu/meetings/astrophysobjects2017/

6) two post-doc positions at IPGP (Paris) on extraterrestrial seismology
First position: seismo-tectonics/Mars Geology on SEIS/INSIGHT
NASA will launch in May 2018 InSight, the first Martian Geophysical Observatory
due to land on Mars by November, 2018. The Institut de Physique du Globe de
Paris (IPGP), PI Institution of SEIS, the primary instrument of the mission is
searching candidates for a two years postdoctoral position in the Institut de
Physique du Globe de Paris (IPGP/Université Paris Diderot/CNRS), Paris, France.
The position is open to a young seismologist/geologist with seismo-tectonics
expertise and/or remote sensing data and seismic data analysis expertise. It will
be associated to IPGP contribution to the Mars Quake Service (MQS), aiming to
locate and characterize Mars seismic activity and to the IPGP-JPL lead Mars
Structure service activities (MSS). The post-doc fellow will prior the SEIS data
acquisition conduct a global mapping of the main characteristics of the crust,
including the topography, the gravity, faults that have surface signature and
geological evidences for crustal layering in the landing site area, and will develop a
research program on the Mars crustal structure and origin and characteristics of
Marsquakes, which will progressively integrate the analysis of the seismic data
gathered after November 2018.
Prior the mission landing, the main resulting product consists of a global GIS
(geographic information system) that integrates all tectonic and geologic
informations. The fellow will integrate data coming from different orbital missions
(namely MGS, Odyssey, MeX and MRO) that include imagery (visible and IR),
altimetry and gravity. Various informations will be derived (crust thickness). Many
seismic faults have potential surface signature. A global mapping of the fault
properties (orientation, offset…) will be perform and used in combination with
other data in order to compute the deviatoric stress at global scale. The fellow will
therefore need GIS expertise and/or a dedicated training as well as general
geophysics experience. Knowledge in planetary data reduction is also welcome,
although not requested. In parallel, the fellow will develop, in collaboration with
other InSight team seismologists, tools to perform source and structure inversions
of the crust with single seismic station techniques.
After November 2018, the fellow will be associated to the data analysis process
and might develop research on Martian quake dynamics, seismo-tectonics and
crustal structure inversions.
2/3 of the position working time will be associated to Scientific tasks associated to
the SEIS data analysis, while 1/3 of the working time will be devoted to project’s
activities.
The position is open and candidate proposal will be examined every 2 weeks until
postdoc recruitment, with first selection date on March 15. Due to ITAR
regulation, this position is open to individuals with single national or third
country/dual national of NATO and/or European Union countries, Australia, Japan,
New Zealand, or Switzerland. Other nationalities are on cases by cases basis.
Net Salary will range from 2100€/month for PhDs without postdoc experience up
to 2900€/month depending on postdocs experience plus other personal benefits.
Salary conditions can be found in more details at:
https://www.dgdr.cnrs.fr/DRH/remuneration/taux.htm (coûts salariaux des
contractuels, residence zone 1, Researcher level).
Proposal must be sent through E-mail to Cette adresse e-mail est protégée contre les robots spammeurs. Vous devez activer le JavaScript pour la visualiser. with email
subject: ‘SEIS INSIGHT Postdoc position’. Information might also be made directly
through email to the SEIS PI ( lCette adresse e-mail est protégée contre les robots spammeurs. Vous devez activer le JavaScript pour la visualiser. )
Proposal must contain:
• Motivation letter with proposed position starting date,
• CV with indication of citizenship and full publication list
• A list up to 3 possible references with name, address, emails and
professional relations, if any.
• Up to 3 pages description of the proposed Research project, including the
constraints developed above.
Second position: Extra-terrestrial Computational seismology
NASA will launch in May 2018 InSight, the first Martian Geophysical Observatory
due to land on Mars in November, 2018. The Institut de Physique du Globe de
Paris (IPGP), PI Institution of SEIS, the primary instrument of the mission and the
helio-astero seismology team of AIM are searching candidates for a two years
postdoctoral position funded by the UnivEarth LABEX in computational planetary
and extra-terrestrial seismology likely extended by a third year following the
deployment of SEIS on Mars. Postdoc will be based in the Campus Spatial Facility,
at University Paris Diderot, Paris Rive Gauche campus.
Seismology is indeed not only expected to gather data on the interior of Mars with
InSight, but is also providing new constraints on the structure of giant planets
through the detection of Jupiter Normal modes (Gaulme et al., 2011), their
possible confirmation with Juno (Durante et al., 2016) or the detection on Saturn
Rings of the signature of Saturn normal modes (Hedman and Nicholson, 2013).
The recent detection of gravitational waves are also triggering renew of research
on the excitation of quadrupole planetary normal modes by gravitational waves
(Coughlin and Harms, 2014), including for new Lunar based seismometers.
The goal of the postdoc is to develop and validate in the 2017-2018 timeframe a
complete modeling software of normal modes and Long Period seismic waves,
valid for both terrestrial planets (with and without atmosphere with a strong focus
on Mars) and fluid bodies (both giant planets and stars with a focus on Jupiter)
which will gather the expertise of the two labs (IPGP, AIM) who work respectively
in Earth/terrestrial planets seismology and in helio and astero-seismology.
This first task will be the integration of the most recent evolutions in
computational seismology, including recent tools such as InstanSEIS, AxiSEM,
SPECFEM, DSM and Higher order perturbation theory for Normal modes and
surface waves. For Normal modes, this development will integrate the
computation of seismic, gravitational or strain signals generated by a variety of
sources, from quakes, impacts, global fluid turbulences to gravitational waves.
Practically, the software will have to be made available though github to all Labex
and selected Insight/SEIS partners. During the two first years of the postdoc, 40%
of the research time will therefore be allocated to Mars computational seismology
efforts while other 40% will be to giant planets and stars computational
seismology. The remaining 20% will be made available for the selected postdoc
personal research in other aspects of computational seismology including for
Earth and other bodies.
The extension of postdoc during the third year will allow the selected postdoc to
contribute to the seismic data analysis of the SEIS experiment with a focus on long
period seismic data, including modeling and inversion of long period seismic data
gathered during the first year of InSight operation, the later made through MCM
and/or deep learning inversions in the frame of the Mars Quake service (Panning
et al., 2016). During this extension, 100% of the effort will be reserved to InSight,
including for 35% associated to project activities related to SEIS operation.
The postdoc will be integrated in the InSight/SEIS team as collaborator, under the
sponsorship and supervision of the SEIS PI. He will benefit to the access to parallel
computing facilities, either available at IPGP or in the framework of InSight/SEIS at
French National level.
The position is open and candidate proposal will be examined every 2 weeks until
postdoc recruitment, with first selection date on March 15. Due to ITAR
regulation, this position is open to individuals with single national or third
country/dual national of NATO and/or European Union countries, Australia, Japan,
New Zealand, or Switzerland. Other nationalities are on case by case basis.

8) Compressible Convection Conference 2017, 18-22 septembre 2017, Lyon
Scope of the conference: Most studies of convection rely on approximate models of the governing equations: Boussinesq or other sound-proof models, anelastic, pseudo-incompressible... In the geophysical and astrophysical contexts, it is difficult to decide which model is most appropriate and the answer may depend on the particular scientific question under scrutiny. During this conference, we will discuss the limits and applicability of any model of convection in any of the diverse forms of convection: it may be driven by thermal, compositional, phase change or magnetic buoyancy effects. We will also consider compressibility effects in stably stratified cases and their impact on internal gravity, inertial or Alfven waves. In summary, all contributions about the limitations, failure or improvements of convection models are welcome, from an observational, experimental, numerical or theoretical point of view.

10) EPSC conference, Riga, September 17th-22nd, session on "comet C/2013 A1 (Siding Spring) at Mars"
On October 19th 2014, Mars experienced a close encounter with Comet C/2013 A1 (Siding Spring), at a distance of only 141,000 km, or one third the Earth Moon distance. The gaseous coma washed over Mars and Mars passed directly through the cometary debris stream. This unique event enables the scientific community to investigate the response of the Martian atmosphere, as this may have implications for overall atmospheric evolution. The objective of the session is to bring together all the multiple efforts of the scientific community in this specific topic and to encourage people to continue studying the topic in more deepness, as there are plenty of available data currently not being used. All the aspects of the Mars-comet interaction are welcomed, such as delivery of pickup ions, impact of high energetic particles, induced magnetosphere, escape rates, dust deposition, ion-neutral chemistry, atmospheric dynamic effects, formation of metallic layers and meteoric smoke particles, ice cloud nucleation, etc.
Please find more details on the session here: http://meetingorganizer.copernicus.org/EPSC2017/session/26052
Deadline for abstract submission: May 3rd, 2017.
Feel free to re-send this email to whom may be interested.
With best wishes,
Beatriz Sanchez-Cano, Olivier Witasse, Matteo Crismani, and John Plane.
