Sea EP is the second EP from Doves. It was self-released on the band's Casino Records label on 24 May 1999 on limited CD and 10" vinyl. The band dedicated the EP to Rob Gretton, who helped fund Doves' early releases as well as when the band played as Sub Sub. Rob died of a heart attack only a few days before the EP was released. In the music video for "Sea Song," the opening title card reads "For Rob."
