The main areas of focus will be 1) the measurement and interpretation of global datasets of body-wave attenuation - special emphasis will be on constraint of lateral variations in Q structure which will complement other studies that use surface waves. An attempt will also be made to constrain the form of the absorption band in the earth; 2) the use of body-waveform modeling to handle triplication regions of the seismograms - the method employs a 3-D ray tracer which is also useful for looking at non- linear behavior of travel-time perturbations and 3) modelling of entire global datasets including various geodynamical prejudices. ***
