The Laurentian Abyss is an underwater depression off the eastern coast of Canada in the Atlantic Ocean.^[1] Not a trench, but more of an "underwater valley", it is estimated to be at most ~6,000 meters in depth. The Laurentian Abyss is a product of glaciation and water currents from the Saint Lawrence Seaway.^[2]

The trench is populated by hydrothermal vents with their own ecosystems independent of sunlight.^[3]

[edit] In popular culture

The Laurentian Abyss has been a feature of at least three pieces of fiction media.

• It was featured as the covert rendezvous point for Soviet and American submarines in the 1990 technothriller film The Hunt for Red October. The location, however, was not used in the original 1984 novel by Tom Clancy.

• In the 2007 film Transformers, the remains of Megatron, Blackout, Brawl and the other defeated Decepticons are dropped into the abyss. It is theorized that the pressure and extremely low temperatures at this depth would crush and bury the evil alien robots. However, the film erroneously states that the abyss is the deepest point on Earth; the actual deepest point is the Challenger Deep, a section of the Mariana Trench in the Pacific Ocean.

• In the 2009 film Transformers Revenge of the Fallen, the remains of Megatron and the other decepticon remains are found at the bottom of the Abyss, by his Decepticon comrades and then he is reactivated. Also Ravage is also seen jumping out of the Abyss and The Decepticon Protoforms and The Fallen are seen climbing up a sinking destroyed ship that is about to sink into the Abyss waters.
