New paper reports chimneys from 5700m deep in Mariana forearc

New co-authored, open-access paper published in the journal Geochemistry, Geophysics, Geosystems! [Link]

This study reports three types of brucite-carbonate chimneys from the deepest known serpentinite-hosted vent in the world, the 5700 m deep Shinkai Seep Field in Mariana forearc. Although mainly a geochemistry/geology paper, the chimneys are inhabited by some megafaunal animals and brief descriptions of the colonies are included. Molluscs are also present, such as Provanna snails. The paper is open-access so anyone can read it for free!
