Solar supergranulation plays an important role in generating and structuring the solar magnetic field and as a mechanism responsible for the 11- year solar cycle. It is clearly detected within SOHO/MDI Dopplergrams, from which a variety of properties may be derived. Techniques that extract spatial, temporal, and kinematic characteristics and provide comparisons for the two most recent solar minima are described. Although supergranule lifetimes are comparable between these minima, their sizes may be slightly smaller during the recent minimum.
