AOGS2017 Session Announcement: Earth Rotation and Reference Frame


[We apologize if this is a duplicate message.]


Dear Colleagues,

We would like to draw your attention to the solid earth session (SE09)
on Earth Rotation and Reference Frame at the 2017 Asia Oceania
Geosciences Society (AOGS) annual convention to be held in Singapore, on
August 6-11, 2017, and cordially invite you to submit related abstracts
to this session. 

The deadline for abstract submission is February 15, 2017 (which will
likely be extended as always).

You can use the following link to submit an abstract:

http://www.asiaoceania.org/aogs2017/public.asp?page=abstract.htm

The session description is below. We look forward to seeing you in
Singapore this summer!

Thank you!

Jianli Chen, Richard Gross, Olivier De Viron, Haoming Yan


AOGS2017 Solid Earth Sciences, SE09: Earth Rotation and Reference Frame

Conveners:

Earth rotation is driven by mass transport and redistribution within the
Earth geophysical fluids system, including the atmosphere, hydrosphere,
ocean, cryosphere, mantle and core. Although relatively small, the Earth
rotational changes, represented by polar motion and length-of-day
variation have been measured by space geodetic techniques with
increasing, unprecedented accuracy, opening up important new avenues of
research that will lead to a better understanding of global mass
transport processes and of the Earth’s dynamic response. For the
quantification of many geophysical phenomena, e.g. sea level change,
polar ice sheets mass balance, glacial isostatic adjustment and plate
tectonics, a global reference frame, such as the International
Terrestrial Reference Frame (ITRF), is needed. This session solicits
contributions ranging from geophysical interpretations of observed Earth
rotational change using advance numerical models estimates, in situ
measurements, and satellite altimetry and gravimetry measurements,
theoretical formulation and determination of reference frames (and
geocenter motion), to geophysical applications of Earth rotation and
reference frame in improving the understanding of the Earth geodynamic
change and global mass transport and redistribution.
