[3] On July 23, 2006, Isis performed Oceanic in its entirety at KOKO, Camden Town, London as part of the All Tomorrow's Parties curated Don't Look Back series.

[4] This performance was recorded and eventually released in 2009 as Live V. The track "Weight" was used in the 20th episode of the 1st season of the 2007 television series Friday Night Lights.

[6] The album’s style marks a distinct departure from their previous sound; up until this point, Isis had been characterised by crushing, distorted guitars and a coarse, unforgiving tone.

With this album came the introduction of lengthy periods of clean guitar, large amounts of ambient noise and female vocals; a notable post-rock influence, first hinted at on SGNL>05 and Celestial.

[20] The change of style proved trying for some long-standing fans, but beneficial in garnering a greater fanbase and the Neurosis-Godflesh comparisons began to weaken.

The band itself cites Isis as an influence, and a review in Terrorizer posits that Oceanic covered "fairly similar aquatic terrain" as their release Salvation.

[29] The album was remixed in a series of four vinyl EPs, named Oceanic Remixes/Interpretations Volumes I-IV and released on Robotic Empire Records in 2004 and 2005.
