A cold seep (sometimes called a cold vent) is an area of the ocean floor where hydrogen sulfide, methane and other hydrocarbon-rich fluid seepage occurs, often in the form of a brine pool. "Cold" does not mean temperature of seepage is lower than surrounding sea water. On the contrary, its temperature is often slightly higher. Cold seeps constitute a biome supporting several endemic species.
Cold seeps develop unique topography over time, where reactions between methane and seawater create carbonate rock formations and reefs. These reactions may also be dependent on bacterial activity. Ikaite, a hydrous calcium carbonate, can be associated with oxidizing methane at cold seeps.

Famous quotes containing the words cold and/or seep:
“I have been told, that in some public discourses of mine my reverence for the intellect has made me unjustly cold to the personal relations. But now I almost shrink at the remembrance of such disparaging words. For persons are love’s world, and the coldest philosopher cannot recount the debt of the young soul wandering here in nature to the power of love, without being tempted to unsay, as treasonable to nature, aught derogatory to the social instincts.”
—Ralph Waldo Emerson (1803–1882)
“Pushkin’s composition is first of all and above all a phenomenon of style, and it is from this flowered rim that I have surveyed its seep of Arcadian country, the serpentine gleam of its imported brooks, the miniature blizzards imprisoned in round crystal, and the many-hued levels of literary parody blending in the melting distance.”
—Vladimir Nabokov (1899–1977)
