Abstract

<p>From 16th November to 15th December 2016, hydrothermal field was drilled at Izena Hole in Okinawa Trough using D/V Chikyu. Five sites were drilled along the transect line from the top of the northern mound of the HAKUREI site to the east side, and 1 site about 500 m northwest of the mound as the reference site. From the collected cores, samples for headspace gas measurement and interstitial water extraction were taken on the ship. Regarding the interstitial water extracted from the sample, pH, alkalinity, nutrients and hydrogen sulfide concentration on ship, and main elements concentration and boron isotopic ratio were measured on land. For samples for gas measurement, hydrocarbon and hydrogen concentrations were measured on ship and carbon isotopic ratios of methane on land.</p>
