Atlantis project

From Memory Alpha, the free Star Trek reference

The Atlantis Project was a project initialized in 2367 as a way of creating a new continent in the Atlantic Ocean on Earth.

Jean-Luc Picard was offered the job of head director by his childhood friend Louis, a supervisor for the project, shortly after Picard's rescue from the Borg. Picard turned down the offer, preferring to return to the USS Enterprise-D. Having kept up with the project through journals, he wondered how they planned to accelerate the build-up on the underside of the mantle without increasing the stress on the tectonic plates, and suggested to Louis to use harmonic resonators to relieve the tectonic pressures.

According to the non-canon novel "Stone and Anvil", it already existed as a vital project in the 2350s.
