Released in 1998, Imagined Oceans is an album by WelshcomposerKarl Jenkins. This work was inspired by thirteen lunar mare for which the tracks are titled. The musical style is similar to Jenkins's Adiemus compositions and each track explores the meaning of its Latin name through various musical techniques. Unlike most of the Adiemus pieces, the lyrics for Imagined Oceans consist of syllables from the tracks' titles rather than invented text.
Jenkins has used the theme from several tracks in his other works. "Lacus Pereverantiae" shares its theme with "The Dagda" from Adiemus IV: The Eternal Knot. "Palus Nebularum" shares its theme with "Isle of the Mystic Lake" also from The Eternal Knot.
