The last few years have seen a wave of scientific breakthroughs in mineral magnetism – from theoretical findings to more applied studies. Magnetic measurements and imaging provide unique and valuable data for a wide range of applications in the geosciences and planetary sciences, notably in tectonics, paleoclimate and paleoenvironmental research, studies of the Earth's deep interior, and exploration of planetary surfaces and interiors. This special collection also hopes to attract modeling and experimental studies and studies into atomic and nanoscale magnetic properties, as well as satellite, airplane, ship, and undersea surveys and imaging to illuminate the frontiers of magnetic science.
This special collection is open to submissions jointly in Geochemistry, Geophysics, Geosystems and JGR-Solid Earth. Manuscripts should be submitted through the GEMS website. For additional information please contact: firstname.lastname@example.org.
Submission acceptance begins: 18 July 2017

The proliferation of field expeditions focused on characterizing natural gas hydrate as a potential energy resource has spawned widespread interest in gas hydrate reservoir properties and associated porous media phenomena. This special collection invites contributions describing laboratory experiments that constrain the geomechanical, hydraulic, thermal, and/or geotechnical properties of hydrate-bearing sediments, as well as observational studies related to the interaction of multiphase pore fluids and soils during hydrate formation, long-term thermodynamic stability, and/or dissociation. Numerical modeling or theoretical studies that advance these topics with application to naturally-occurring gas hydrates are also welcome. The special collection will also include papers that make fundamental advances in the interpretation of borehole logging data or field-scale seismic data in terms of reservoir properties or the interaction of gas hydrates with porous media. Contributions that describe field surveys without elucidating new approaches for inferring reservoir properties are not appropriate for the special collection.
Call for Papers for “Ten years after the Wenchuan earthquake: new insights into the geodynamics of eastern Tibet"
Submission acceptance begins: 01 July 2017
Submission deadline: 31 January 2018

In 2008, the Mw 7.9 Wenchuan earthquake killed > 80,000 and injured more than 370,000 people in the province of Sichuan, China. About five years later, Mw6.6 Lushan earthquake occurred on April 20, 2013, only ~90 km further south. Both events were along the Longmen Shan thrust belt in eastern Tibet. The questions posed by these two events still reverberate in the Chinese and international geoscience communities. Almost ten years on, we envisioned there have been new data sets, observations, and modeling, thus it is a good time to look back on what we learned from those events, since interest in the evolution of eastern Tibet has not abated during that time. Here we propose an AGU joint special issue on Wenchuan retrospective that will span Tectonics and JGR-Solid Earth. We welcome contributions which cover the tectonics of eastern Tibet, the seismology of the earthquake, and the surface response following the earthquake. All these contributions will provide new insights into the gedynamics of the eastern Tibet.
Call for Papers for “Seismic and micro-seismic signature of fluids in rocks: Bridging the scale gap ”
Submission acceptance begins: 01 October 2016
Submission deadline: Extended to 30 June 2017

Seismology, geophysics and rock physics are disciplines aimed at understanding the structure and dynamics of the subsurface using seismic and micro-seismic monitoring techniques. Typical applications requiring this knowledge include exploration for and production of hydrocarbon resources, monitoring carbon dioxide geo-sequestration, and recovery of geothermal energy. A common denominator for these applications is the need to characterize fluid migration, substitution and diffusion and their effects on underground rock formations during fluids injection and withdrawal operations. The scales of observation and frequency of probing involved cover a wide range: from millimeters (rock physics experimentation) to kilometers (seismology) and from sub-hertz to megahertz. Contrasting observations or interpretations are often made at these various scales/frequencies, and discrepancies need to be explained in physical terms in order to predict effectively the evolution of the rock formation of interest. Bridging this scale gap motivated the research workshop “Seismic and micro-seismic signature of fluids in rocks: Bridging the scale gap” held June 13, 2016 at the University of Cergy-Pontoise, France, and jointly sponsored by the Institute for Advanced Studies and the Department of Geoscience and Environment. The objective of the workshop was to gather seismology, geophysics and rock physics experts to share information on laboratory experimentation and field studies on reservoir rocks such as sandstones or carbonates, and tighter rocks such as granites. The practical aim of the workshop was two-fold: (i) discuss the commons and differences between the scales of observation; (ii) identify the knowledge gaps and explore the possible ways to overcome them in order to reconcile laboratory experimentation and field data interpretation. This exchange of information will ultimately contribute to a better understanding of how fluid injection, substitution and diffusion in the subsurface affect pore/effective pressure, micro-seismic activity, rock strength, and the potential for faulting and fault reactivation. The discussions at the workshop were guided by the following questions:
• How to optimize the design of laboratory experiments to provide the most relevant data for field-scale interpretation;
• How to optimize the design of field testing/monitoring and making the best use of laboratory data;
• Identify the best-suited theoretical tools for upscaling.
This Special Collection in the Journal of Geophysical Research – Solid Earth will be a record of our state of understanding of the impact of fluids on our ability to remotely monitor the evolution of underground rock formations in a reliable way. Manuscripts are invited for a special section related to the theme of the workshop.
