Time Wakes "healed themselves" after primitive time travel excursions were halted. Until that time, however, they presented themselves as shimmering blue-white rings. People could step directly into the rings and be transported to wherever the Wake took them. The sign of a Wake closing was a gradual constriction of the circumference of the ring. It was possible for Time Wakes to be lethal, if one attempted to enter at a point where the circumference could not accommodate one's personal size. Tasq, for instance, died because he tried to step into a Time Wake that had closed too far. (PROSE: Time Wake)
TARDISes additionally left temporal wakes, which were areas in the vortex where it had recently been or would be, meaning a TARDIS could cross its own wake. (PROSE: Imperial Moon) Because she merged with part of his TARDIS, the Seventh Doctor was able to track the wake of the Timewyrm and follow her. (PROSE: Timewyrm: Genesys) The Headhunter programmed Morbius' stellar manipulator to follow the Doctor's TARDIS's time wake as she locked it onto Lucie Miller's DNA. (AUDIO: Worldwide Web) Similarly, the ruptured core of a Dalek time machine left a temporal wake that dragged the Doctor's TARDIS off course. (AUDIO: The Elite)
Due to his actions in the past on Skaro, the Fourth Doctor caused a "timewave" that interfered with the Time Ring and caused himself, Harry, and Sarah Jane to be scattered across the Adelphine Cluster. (PROSE: A Device of Death)
