EOI scientists are participating in a deep-sea expedition to the Lost City hydrothermal vent field in September 2018. The Lost City is a beautiful seafloor formation whose unique scientific and cultural value has brought it under consideration for special protection by the UNESCO World Heritage Centre and International Union for Conservation of Nature. The Lost City is also featured in many studies on the origin of life and the search for life in the solar system. This will be the first US expedition dedicated to the Lost City since 2003-2005.
