During ROPOS Dive R1838, the temperature-resistivity instrument was taken to the seafloor for installation on a follow-on dive. The RAS-PPS-2015 sampler (hydrothermal fluid - microbial DNA sampler) was found after being deployed by the R/V Thompson's trawl wire onto the seafloor. The dive ended with recovery of the mass spectrometer-2014. The tool sled was left on the bottom for recovery on the next dive. Credit: NSF-OOI/UW/ISS; V15.
