In the coming years the Atacama Large Millimeter Array (ALMA) will provide a new window into the physics of protoplanetary disks and Gas Giant Planet (GGP) formation. We use a 3D, non-LTE, microturbulent radiative transfer code coupled with recent 3D hydrodynamic simulations of gravitationally unstable protoplanetary disks to predict spectral signatures of disk dynamics and planet formation detectable with ALMA. The radiative transfer code can rotate the hydrodynamic protoplanetary disk model and simulate line-of-sight spectra for different viewing geometries. By using the high density tracer HCO+ J=7-6, we find that ALMA will be able to detect massive, infalling protoplanetary clumps and disentangle motions associated with spiral density waves within a protoplanetary disk. In our talk we will present results from the simulations and further discuss the sensitivity of ALMA to these features.
