Growing up in Chicago, Brooke Dolhay ’25 enjoyed reading about the world’s oceans, but her Midwest location never allowed her to take much of a deep dive into them.
That continued into college as she followed her parents, Amy ’95 and Kevin Dolhay ’94, to Kalamazoo College. From a distance perspective, the move got her only marginally closer to making waves along saltwater shores in her chosen field of biochemistry. Then a whale of an opportunity came along for her Senior Integrated Project (SIP).
Influenced by her study abroad experience in Oaxaca, Mexico, Dolhay decided to investigate programs overseas.
“I saw the SIP as an opportunity to do exactly what I wanted to do and create my own experience, so I started randomly Googling phrases like ‘diving internships,’ and I came across the Institute for Marine Research (IMR), which is in the Philippines,” Dolhay said.
She decided to apply to the institute and was accepted into IMR’s summer program, conducting research into the coral reef there and why so many of them are dying. The only issue she needed to resolve in advance was funding an experience in the Philippines, which she discussed with her SIP advisor, Regina Stevens-Truss, a professor of chemistry and department co-chair.
“She said the college actually has a lot of different ways to fund a SIP experience, so I emailed a bunch of people about it,” Dolhay said. “I talked to the Center for Career and Professional Development. They had an unpaid internship stipend, so I applied to tha.t. The Center for International Programs has a list of grants on its website for SIP-related funding, so I also applied for the Hough Grant through the Hough Foundation. That helped me, too, and the experience ended up being fully funded, which was awesome.”
With financing concerns behind her, accepting the one-month opportunity was a no-brainer.
“I was excited because I also traveled to Europe with family, but I’d never been as far away from home as the Philippines,” Dolhay said. “I really loved my study abroad experience, too, so I knew I could travel alone, and I thought ‘why not?’”
IMR is located on the small island of Negros Oriental, which required her to take flights from Chicago to Los Angeles, Los Angeles to the Philippines capital of Manila, and Manila to Negros Oriental. The remote location, where cars are uncommon, forced her to ride around on a moped with the nearest town with a mall being about 40 minutes away.
Once settled, though, Dolhay found her first order of business was to prepare for her research by earning an advanced certification in scuba diving. For her first six days, she completed two dives in the morning and two in the afternoon in a physically demanding process.
Then came her research. Going in, she knew that algae and corals have a symbiotic relationship. Typically, algae provide corals with food and photosynthesis, and the corals give algae access to sunlight and a protected environment. Climate change, however, is warming ocean waters. That causes corals to bleach and then expel algae. The processes are killing off some varieties of fish and are affecting humans, too, as island communities have less fish to eat and less protection from disasters such as hurricanes and tsunamis.
Armed with this knowledge, it was Dolhay’s job to operate a variety of underwater cameras while scuba diving before using software to collect data and analyze the pictures.
“We were looking at the corals, the fish and also the ocean floor,” Dolhay said. “Nearly all of IMR’s methodologies involved a kind of camera. For the fish, we had a long metal bar that had two cameras on either side of it. For the ocean floor, we had a GoPro we used along a transect line where we would take pictures about every meter or so. For the corals, we would swim along a transect line and look for different obstructions.”
IMR will continue the research that she helped start for a few more months yet. But within the data, a variety of scientists like Dolhay are finding reason for hope.
“There are labs at different universities that are trying to genetically modify corals so they can grow in the increasing water temperatures,” she said. “IMR also is growing baby corals under water in a coral nursery and using the larvae to try to respawn areas that haven’t been doing well. There’s a lot of cool science going on between genetic modification and artificial development with scientists dropping cages like the ones fishermen use to replant corals using zip ties. A lot of the fish are attracted to that because it works like a real reef.”
The opportunity in the Philippines, Dolhay said, clearly wouldn’t have been available to her had she decided to attend a school other than K.
“I’ve talked with friends who have gone places like the University of Tampa and the University of Illinois,” she said. “They don’t have this kind of experience at all. They might work in a lab with a professor, but I don’t hear of them speaking about outside opportunities where they can get involved and be supported by the college at the same time. I really love that I could do that.”
And now, she expects the experience will be beneficial as she applies for master’s programs in environmental science at institutions such as DePaul University, the University of Colorado at Boulder, and the University of Illinois Chicago.
“I’m really interested in decarbonization and the chemical side of being a biochemistry major because the CO2 that we emit is directly affecting the oceans and the way that the corals grow,” she said. “I’m also looking into ocean acidification and how we can try to mitigate that because it just keeps happening as a result of our carbon emissions. In the meantime, I’m trying to find ways to educate others on the importance of being aware of your carbon footprint and doing the little things throughout the day that can help the planet.”
