A Time Wake was an anomaly in the Time Vortex caused by the use of (primitive) time travel technology, (PROSE: Time Wake) although DARDISes and TARDISes also left them. (AUDIO: The Elite)
They were "rather like the wake left behind by a ship at sea." They presented themselves as shimmering blue-white rings that people could step directly through and be transported to wherever the Wake took them. They "healed themselves" after primitive time travel excursions were halted, the circumference of the ring closing in a gradual constriction, proving lethal if one attempted to enter at a point where the circumference could not accommodate their personal size.
The Sixth Doctor told Peri Brown encountered a Time Wake created by Tasq, a Time Engineer from the planet Bestonas, that connected London in January 1986 to London in 1720. (PROSE: Time Wake)
TARDISes left temporal wakes as areas in the vortex where it had recently been or would be, meaning a TARDIS could cross its own wake. (PROSE: Imperial Moon) Ramón Salamander believed he had drifted through the Time Vortex in the wake of the Doctor's TARDIS, arriving on Earth only minutes after him in the 1960s "or perhaps another decade." (COMIC: The Heralds of Destruction, TV: The Web of Fear)
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 Eighth Doctor's TARDIS's time wake as she locked it onto Lucie Miller's DNA. (AUDIO: Worldwide Web)
The ruptured core of a Dalek time machine left a temporal wake that dragged the Fifth Doctor's TARDIS off course. (AUDIO: The Elite)
