The last week has been an eventful one where time has seemed to fly by quickly. We began the week with a ship-wide fire drill where there was a fire in the main lab, our primary muster station. Luckily, common sense prevailed and all of the scientists found the secondary muster area at the CTD hangar. As the week progressed, we began tackling an issue that has been plaguing our XBT (Expendable Bathythermograph – sound speed velocity) data. Multiple XBT probe deployments were showing noisy false data before the probe reached the water so we started troubleshooting. It was noted that the data was normal when the wire for the XBT launcher was not touching the deck so we checked the wire insulation for nicks and we made some repairs. It worked! Scientists were happy and techs felt proud. Truly a terrific moment on the R/V Neil Armstrong followed by a highly entertaining scientific meeting. Arman, a visiting scientist, gave a fantastic no-BS presentation on volcanology pointing out the key ingredients for explosive eruptions which are volatiles. It is not widely known that volatiles in magma, mainly water, cause the explosive eruptions that we envision when we think of volcanoes (or see when we watch Dauntes Peak). Later in the week, we visited the engineering department and got a full tour of their spaces. We also learned how to replace bearings on a CPP (controllable pitch propeller) motor. Overall, a very educational and fun week!
