Summit of Escargot

Summit of Escargot

The summit of this hydrothermal chimney, called 'Eascargot', has a striking resemblance to a snail. A 270°C actively venting site (two small white chimneys mid structure) will host a cabled temperature-resistivity sensor there in 2014. This sensor will provide real-time data on the fluid chemistry (chlorinity) -temperature relationships inside the vent. The instrument was designed by Marv Lilley, University of Washington.
