I just wrapped up my first week with the Alvin Team, and it’s been amazing in more ways than one. Upon arriving in Oregon, I finally got to meet the team in person. Everyone has been wonderfully patient and kind, showing me the ropes of both their operations and, of course, the engineering behind Alvin. I also met the crew of the RV Atlantis during a Labor Day picnic and cookout they hosted on the dock before we set sail.
This week, I was introduced to the sub and its critical systems. Since Alvin hadn’t been operated for about a month, we spent three days on maintenance, which I was able to observe and help with when possible. Some of the tasks I participated in included ensuring pressure compensation in the junction boxes and tubing that house communication cables, pressure testing the check valves on the main and variable ballast systems, and installing the seawater filter for the variable ballast. I also learned how the team inventories and stores spare parts, as well as the strict protocols for replacing them. Their attention to detail is remarkable—every component must meet precise standards, and even the slightest thread damage can make a part unsuitable for dive operations. I also witnessed the installation process of the batteries; they provide 120 volts to the sub. We rolled out Alvin to expose a hatch between the tracks in the hangar that allows access to the hold where the batteries are stored and maintained. The batteries were lifted into the sub using hydraulics.
In preparation for the first engineering dive, I helped remove the coral-cutting claw from the robotic arm and replace it with a three-pronged gripper more suitable for this expedition, collecting high-temperature water samples at hydrothermal vents. We also held the “weight party,” where we stacked steel plates to aid Alvin’s descent on the Juan de Fuca Ridge. Unfortunately, our first dive was canceled after a recovery buoy detached from a Canadian mooring line. Since we were nearby, the RV Atlantis was asked to recover it, which we did.
Even so, I’ve already learned so much about plumbing and mechanics in just one week, and I’m excited to see the data and pictures that Alvin collects after all our dives are complete!
