Global compilation of confirmed and inferred vent sites

A searchable database for more than 550 confirmed and inferred hydrothermal vent sites is available at http://www.interridge.org/irvents/. The data set was compiled by Stace Beaulieu (WHOI) using lists maintained by Mark Hannington (University of Ottawa, Canada), Ed Baker (NOAA/PMEL, USA), and Sven Petersen (IFM-GEOMAR, Germany).
