Learning From Destruction

“The research is motivated by curiosity,” said Avery Cook Shinneman, a geology and environmental studies lecturer at the University of Washington Bothell. “No one knows what happens after a large eruption like this.” 

During a recent three-day stint in the field, Alex was joined by Avery; Kena Fox-Dobbs, associate professor of geology and environmental policy and decision making at Puget Sound; Jim Gawel, associate professor of environmental chemistry and engineering at University of Washington Tacoma; and Angelica Lucchetto, an environmental studies major from UW Bothell. The group piled into a small rowboat outfitted with an outboard motor. Their destination? Small, white tents floating on top of logs lashed together with rope and eyebolts. 

The manmade log rafts are safer and easier to study than the unpredictable, massive log mat that occupies Spirit Lake, and they serve as floating laboratories where the research team can gather water samples, scrape biofilm from the underside of the logs, and collect insects from the white tent traps. “We’re trying to understand how important the log mat is to life here,” Kena says. “These mats provide a surface for life and give us a fingerprint of what’s going on.”

Alex’s work aims to help identify whether the bacteria that grow on the underside of the floating logs are an important source of nutrients for the lake ecosystem. At each log raft, he gets out of the boat, gains his balance on the logs, and scrapes the slimy greenish bacteria into a test tube that is placed in a cooler. Those samples will later be analyzed by Kena and Avery, who will determine what kind of bacteria is there, what they do, and how they fit into the larger lake system. 

This type of research falls into a field of study called geochemistry, which uses chemistry to investigate Earth and environmental systems. It’s a subject that piqued Alex’s interest early on in his studies. 

“It was so much more interesting than morphology, which is learning about rocks and land forms,” he says. “Geochemistry is the study of processes, and is a lot easier to apply. You can see it happening, and it’s based on research I enjoy doing.”

When the opportunity arose to participate in geochemistry research through one of Puget Sound’s Summer Science Research Grants, Alex jumped at the chance. “I wanted an opportunity to set me up well for writing a thesis and applying to graduate school,” he says. “Summer research wasn’t always something I thought I would do, but I’m really happy I did.”
