On 5 July we were in the right place and time to encounter a group of approximately 300, or more Pacific white-sided dolphins. These dolphins remained somersaulting, leaping, porpoising and surfing around the ship for more than 1.5 hours. --Photo by Suzanne Yin, marine mammal observer onboard the TE SubCom Dependable.

The temperature-resistivity instrument measures, in real-time, the temperature of black smoker fluids (>400°C) and the resistivity of the fluids as a proxy for chlorinity. Vents at Axial Seamount are boiling, producing fluids that are very low in chloride content (salts). Boiling is an important processes because it enhances precipitation of precious metals in seafloor black smokers.

crumbly rock and round pink corals
Beautiful soft corals inhabit the hard carbonate substrate of the 60 m tall Pinnacle structure west of the major seep sites at Southern Hydrate Ridge. This site, at a water depth of ~ 550 m, hosts numerous white and orange bacterial mats, marking sites of weak venting of methane-rich fluids. The almost pumice-like structure of the pinnacle provides ample places for animals to live - small shrimp are extremely abundant. The Pinnacle is likely the fossilized 'throa'/plumbing system for a more ancient seep site that once inhabited this area.
