Description: Cold seeps are formed in a similar way to hydrothermal vents, but with a slower and cooler leaking of mineral-laden sea water. They also may form rich deep sea habitats fuelled by methane via chemosynthetic bacteria living independently or symbiotically with a variety of invertebrate species such as tube worms. New Zealand’s cold seep ecosystems were first explored and sampled in 2006 with the discovery of one of the largest seep sites in the world containing a variety of sponges, corals, bivalves and tube worms, with some species new to science. All sites surveyed also showed evidence of damage and lost gear from fishing activities. Species found at cold seeps tend to be slower growing than similar species found at hydrothermal vents and seep communities are also at risk from bottom fishing and mining activities. This map includes 44 cold seep locations around New Zealand with information updated from surveys in 2006 and 2007 accessed from the Inter Ridge database.<div><br /></div><div>Locations indicate only known locations and more may be discovered with further exploration.</div><div><br /></div><div>Greinert J, Lewis KB, Bialas J et al (2010) Methane seepage along the Hikurangi Margin, New Zealand: overview of studies in 2006 and 2007 and new evidence from visual, bathymetric and hydroacoustic investigations.
