What’s happening today?
ROV Jason continues with the last stages of the pressure dive and has resumed collecting fluid samples where hydrothermal vents are near pressure benchmarks. AUV Sentry continued mapping the caldera, then was recovered at this afternoon.

|Same plot as above with deflation pressure data that was recorded during the 2015 eruption by an instrument on the Ocean Observatories Initiative Cabled Array network (in orange). We are collecting data during the Axial Seamount 2015 expedition that will more closely tie data recorded during the April 2015 eruption to the previous time-series.
