The cabled digital still camera streams images of Jason (Dive J2-932) live back to shore in real time as the vehicle works at the active hydrothermal vent called 'El Gordo' in the International District Hydrothermal Field - depth is 1500 m, and >300 miles offshore. The hydrothermal fluid sampler, called the RAS, is shown to the left, which allows fluid samples and temperature to be taken for a year. The instrument can be run in "mission mode" where samples are preprogrammed, or in "sponse mode" where missions are interrupted by operators to take samples - such as was done during the eruption of Axial Seamount in 2015.
