Our primary goal is study CO ro-vibrational lines to distinguish disk winds from Keplerian rotation using spectro-astrometry. Such winds play an important role in disk accretion and protostellar feedback. Whereas broad line profiles suggest the presence of winds in embedded disks, these observations will confirm their existence and also determine their geometry which will help constrain models for their driving mechanism.
