AB: We use SWAMIS, a freely available magnetic feature tracking suite, to analyze the destruction of solar small-scale magnetic flux. We track a sequence of high resolution MDI magnetograms to find the destruction rates in a patch of quiet sun. We state criteria for defining the individual magnetochemical destruction mechanisms of merging, cancellation, and disappearance, and determine the contribution of each process to the removal of detected flux from the photosphere. Destruction mechanisms are important to determine because, together with formation mechanisms, they provide information as to the nature of the small-scale dynamo. We present preliminary results and discuss the implications of these rates on models of quiet-sun magnetic flux generation.
