Tim Crone (standing on the Jason elevator) prepares his camera to be launched. The camera was deployed during J2-516 next to a hydrothermal vent in ASHES. The camera will be left on site for a few days and will be used to determine the flow rate of the vent it is aimed at. Photo by Carlos Sanchez

The Jason crew lowers Jason on to the drill sled that will be used to drill into a black smoker. Sensors will be placed into these drill holes in order to monitor temperature of the system and microbial communities within the walls of the vent. Photo by Carlos Sanchez

The red plumes of healthy tube worms wave in the warm, nutrient-rich fluids within the International District Hydrothermal Field.

A combination of satellite imagery and weather forecasts are critical information in our cruise planning.  

Sarah has spoiled all of us on the R/V Thompson with excellent food! and humor. Today, with calm seas and blue skies, she with help from  many of the crew took special effort to treat us to a barbacue.

Collapse basin, which once contained molten basalt, host a small colony of tube worms. Molten 1200°C, basaltic melt commonly forms pools in the subsurface. The top of the lava-filled pool "freezes" and crusts over with crystalline material as it rapidly cools against the overlying 2°C ocean water. Bathtub-like rings form when the melt drains out to other areas on the seafloor. Following drain-backs the roof is not strong enough to support its weight and the roof collapses to the floor of the basin.

An ~ 7 m-tall, diffusely venting chimney in the International District Hydrothermal Vent Field supports dense biological communities of tubeworms, limpets and scale worms.
