This is workshop travel support for 14 junior scientists (mostly graduate students, with a few postdoctoralresearchers) from the USA to travel to Sanya, Hainan China for the Symposium in geophysicalimaging. The NSF of China has some co-funding to support the local accommodations for theinvited speakers, and for the registrations and other conference expenses. IASPEI (InternationalAssociation of Seismology and Physics of the Earth?s Interior), SEG (Society of ExplorationGeophysicists) and EAGE (European Association of Geoscientists and Engineers) have endorsedand listed the Symposium as their formal symposium or workshop.Geophysical imaging is the key for subsurface structural delineation, target detection andproperty inversion. It has a wide range of applications to subsurface resources exploration, crustand mantle structures, earthquake rapture process and fault structure, and shallow targetdetection. Due to the increasingly high complexity of the geological environments for oil/gasexploration and other imaging targets, such as for monitoring CO2 sequestration and pollutioncontrol, and the explosively increased data amount collected by the new acquisition system, highresolution,high-fidelity and high-efficiency imaging methods are highly in demanding. For highresolution,high-fidelity imaging, we need much more phase-space information, such as the maindirection of the local energy flux, instant frequency of the wavefield, rather than a straightforwardspace-domain solution. In other words, we need accurate and efficient propagators with phasespacelocalizations. Such phase-space information is crucial in modern true-amplitude, truereflectionimaging and parameter inversion. With phase-space localized wave propagators, localAVA (amplitude variation with angle), local inversion for reservoir parameters can be performedand the close link between imaging and inversion can be established. Recently emerged seismicimaging methods using fast beam, fast wavepacket and other localized waves, such as beamlet,curvelet, have brought up broad interests in the study of imaging using localized waves. Therelevant researches have been spread to many branches of physics, acoustics, seismology,engineering and mathematics.The symposium is different from othergeophysical conferences and workshops in its broad scope and interdisciplinary interactions. Theintensive invited speeches serves as introductory lectures by the experts of different fields.
