IAG-IASPEI 2017 Monitoring of the cryosphere

Paul Winberry
Dear colleagues,

The joint Scientific Assembly of IAG (International Association of Geodesy) and IASPEI (International Association of Seismology and Physics of the Earth's Interior) will be held at the Kobe International Conference Center, Japan, from July 30 through August 4, 2017 .

The proposed scientific program consists of in total 43 symposia (7 IAG, 27 IASPEI and 9 Joint symposia). Among them, you may be interested in

J01 Monitoring of the cryosphere (see description below)

Abstracts must be submitted at http://www.iag-iaspei-2017.jp/ by February 8, 2017 . Other information such as travel support, registration, accommodation and travel information can be found at the above site.

We look forward to seeing you in Kobe,
Masaki Kanao, Paul Winberry, Erik Ivins, and Mirko Scheinert 

J01 Monitoring of the cryosphere

Convener: Masaki Kanao (National Institute of Polar Research, Japan)
Co-convener: J. Paul Winberry (Central Washington University, USA), Erik R. Ivins (Jet Propulsion Lab, Caltech, USA), Mirko Scheinert (Technische Universität Dresden, Germany)


Several kinds of environmental signals associated with ocean - cryosphere - solid earth systems have recently been detected in both polar regions. Ice-related motions that generate small magnitude events are generally named ice-quakes (ice-shocks) and can be generated by many glacial processes that include calving and basal slip. Cryoseismic waves are likely to be influenced by variations in environmental conditions, and the continuous study of their time-space variability provides indirect evidence of climate change. Glacial earthquakes are the most prominent phenomena found recently in polar regions, in particular at the Greenland ice sheet, new innovative studies from seismology and geodesy are expected by long-term monitoring under extreme conditions in the Earth's environment.

The response and influence on the cryosphere by the solid earth gives rise to a new understanding of earth surface interactions at a crucial time in earth history when global change is driving variations in mass balance of the polar ice sheets. This approach promotes integration of new earth science data into modeling of ice mass balance, ice dynamics, and solid earth responses to mass change. The glacial isostatic adjustment (GIA), the response of the solid earth to the changing mass of overlying ice, produces displacements of the crust measureable by modern geodetic techniques. Much effort has been focused on improving the ice history and earth rheological components in GIA models, as well as obtaining new geodetic measurements to test these models.

Taking these issues into account, the conveners are willing to invite many contributions to a special session on "Monitoring of the cryosphere", which will cover the recent achievements on glacial related seismic events, geodetic studies of the cryosphere dynamics and associated phenomenon observed in polar regions. It is especially encouraged to have contributions treating the observation and modeling of seismic signals involving dynamics of ice sheets, sea-ice, icebergs and glaciers. Although the glacial earthquakes are the most prominent evidence found recently in polar regions, all related topics involving polar geodesy and seismology are welcome, such as the dynamic feature of crust and mantle in the area, comparison of tectonic events and glacier-related seismicity, recent triggered earthquakes and active volcanoes, space satellite and ground based geodesy, GIA, harmonic tremor associated with cryoseismic events, etc.
