A landward movement of the shoreline indicated by a landward migration of the littoral facies in a given stratigraphic unit (Mitchum, AAPG Memoir 26)
A transgression occurs when the rate of sea level rise landward exceeds the rate of sediment input and causes an increase in accommodation, initiating the development of a transgressive surface over which the trangressive sediments of the transgressive systems tract onlap and retrograde.
