Recent studies have shown viruses to be abundant (10⁴ to 10⁴ ml^-1) in marine environments (e.g. Torrella & Morita 1979, Proctor et al. 1988, Bergh et al. 1989, Borsheim et al, 1990, Proctor & Furhman 1990, Wommack et al,. 1992, Cochlan et al. 1993, Paul et al. 1993). --Bacterial viruses in coastal seawater: lytic rather than lysogenic production RM WIlcox, JA Fuhrman.
