<p><b>Seafloor </b><b>Geophysical</b><b> Observations Session at
the Japan Geoscience Union Meeting:</b><br>
</p>

<blockquote>
<p>Dear colleagues,<br>
<br>
I would like to announce that the submission of abstracts has
started for the following JpGU-EGU-AGU joint session in the
2018 JpGU meeting. The session title is "Probing the Earth's
interior with geophysical observation on seafloor" (the
session ID is S-IT24).<br>
<br>
The submission deadline is 8:00 (UTC) on Feb 19.<br>
<br>
If you are interested in the session, please access the
JpGU2018 home page as bellow.<br>
<a class="moz-txt-link-abbreviated"

<br>
Submission to the session "The lithosphere and the
asthenosphere" (S-IT28) convened by Hitoshi Kawakatsu et al.
is also open until the same deadline on Feb. 19. We are
looking forward to seeing you there. <br>
<br>
<br>
=========Session scope of S-IT24===========================<br>
Probing the Earth's interior with geophysical observation on
seafloor<br>
<br>
Most important sites for plate tectonics and mantle dynamics
studies <br>
(e.g., subduction zones, spreading ridges, and hot spots) are
located in <br>
oceanic regions. The coverage of seismic stations is
concentrated in <br>
land areas, which cover only one-third of Earth's surface.
Since 1990s, <br>
technology for seafloor geophysical instruments to explore
deep earth <br>
structure have been advanced, such as broadband ocean bottom <br>
seismographs (BBOBSs), ocean bottom electro-magnetometers
(OBEMs), and <br>
pressure gauge, because observation network in oceanic regions
is <br>
essential for major breakthroughs in Earth sciences. Technical
advance <br>
in the instruments including cabled realtime seafloor networks
have made <br>
the seafloor observation more common and reliable, which
promotes a <br>
number of seafloor observations, both temporary and permanent
networks, <br>
in the last decade. We call for papers on recent scientific
results from <br>
such observation projects, including those on crust and mantle
structure <br>
beneath subduction zones, hot spots, Large Igneous Provinces,
and <br>
spreading ridges. Technical advances for observation in
oceanic regions, <br>
including seafloor instruments and drifting float, proposals
and plans <br>
for innovative observations are also welcome.<br>
<br>
Invited speakers: G Barruol (IPGP), C Rychert (U
Southermpton), R Evans <br>
(WHOI)<br>
<br>
Conveners: D Suetsugu, G Barruol, H Kawakatsu, D Wiens<br>

<p class="MsoNormal"><span class="" lang="EN-US">The Institut de
Physique du Globe de Paris has an opening for 1-2
post-doctoral positions to carry out research in marine
geophysics, initially for 1.5 years with a possibility of
extension up to 3 years. The project is funded by the
European Research Council to acquire ultra-deep seismic
reflection and refraction data across the Atlantic Ocean,
starting from the Mid-Atlantic Ridge to the African
Continental margin, over the oceanic lithosphere of zero age
up to 75 Ma. The scientific objective of the experiment is
to characterise the nature of the oceanic lithosphere down
to the base of the lithosphere-asthenosphere boundary (LAB),
and develop a model of the evolution of oceanic lithosphere
as it cools away from the ridge axis. <br class="">
</span></p>
<p class="MsoNormal"><span class="" lang="EN-US">In 2015,
ultra-deep seismic reflection data (30 s record length)
using a 12 km multi-component streamer were acquired over
the Mid-Atlantic Ridge extending up to 75 Ma and also
crossing the great equatorial fracture zones (Chain,
Romanche and St Paul) in the Atlantic Ocean. In 2017, an
1100 km long coincident refraction data using 71 ocean
bottom seismometer were acquired along the flow line, and in
2018 another refraction data will be acquired across
fracture zones. <br class="">
</span></p>
<p class="MsoNormal"><span class="" lang="EN-US">The
post-doctoral fellow will take an active role in
acquisition, processing and interpretation of these unique
data and integration with other geophysical and petrological
results and carryout numerical modeling. <br class="">
</span></p>
<p class="MsoNormal"><span class="" lang="EN-US">The candidate

experience in analyses of reflection and/or refraction data
