Science Challenges at Sea: A Plumbing Story

January 31st, 2017 by Seaver Wang, PhD student, Duke University

This is my instrument, which is designed to measure dissolved gases in seawater to detect the oxygen produced by algae. Sea Sparkle, my trusty green stuffed plankton assistant, is keeping a careful eye on the data we’re collecting!

When people think of science, the first examples that come to mind are often dramatic triumphs—the moon landing, the invention of DNA sequencing, or the discovery of the polio vaccine. Almost every exciting experimental result, however, is the result of an enormous amount of unseen effort. Thorough preparation, resourceful improvisation, success and failure, and improvement through trial and error are all deeply familiar to any researcher!

At sea on the Falkor, the challenges that we face as a part of ocean science are unique. After all, any unanticipated problems must be solved using only the resources on board our two-hundred-foot vessel.

Our first two days at sea have presented their fair share of challenges. Our cruise plans have changed almost daily in order to adapt to weather patterns and the ship’s limits in terms of speed and range. In the “wet” lab, anywhere from six to eight science team members must work elbow-to-elbow with all of their equipment packed into a space little larger than an examination room at the doctor’s office.

For my research, which involves measuring dissolved gases from seawater to detect plankton activity, plumbing has been my biggest enemy so far.

The seawater I am measuring is piped continuously aboard ship via a pump, and this water is available from only two outlets in the already-crowded lab. My original plan to use seawater from one of the two faucets was scuppered when a crucial valve broke, spraying the lab with ocean water like a fire hose! After shutting the faucet and confirming that none of our sensitive electronic instruments had been damaged, we realized that I would now have to take my water from the second outlet—located on the opposite side of the room from where I had set up my seawater supply tubing…! In addition to reorganizing all of my plumbing, I would also have to find materials to connect to the second faucet, which uses a different connection from the first.

Luckily, scientists can be pretty inventive! My seawater supply pipe was moved to hang from the ceiling in order to cross the room, and I borrowed parts from other members of the science team in order to fit my tubing to the new faucet. Sharing the lab space is also an important part of ocean science, and so Ryan, another scientist on board, graciously moved some of his equipment to give me access to the faucet.

When doing science at sea, it’s also important to learn from mistakes and bad luck quickly. This time, we fitted double metal clamps to the faucet connection to reduce the risk of unleashing a second fire hose event. With that final step, my plumbing was finally usable, allowing me to switch on my instrument and start collecting my valuable data!

In the end, we spent several hours fixing this incredibly boring problem—one which has very little to do with actual science. Paradoxically, however, all of our tinkering with tubes and faucets was essential in order to perform my research. This is just one of the many small challenges that we have dealt with as we prepare for one of the busiest parts of our expedition. Even though many of our problem-solving stories will never be mentioned when we publish our research results, they are just as much of a part of our science as designing experiments or picking locations for the Falkor to explore.

It’s little challenges like this that help me remember that every scientific discovery, great or small, is built on a huge foundation of invisible work!
