Working with NASA is a dream for most scientists. And it’s something a group of University of the Fraser Valley (UFV) students were able to experience during a recent research trip to south central B.C.
The group spent two days at Kelly Lake, near Clinton, in late July, collecting data to learn more about the lake’s history.
The lake is of interest to NASA as it contains unique rock formations called microbialites, which are considered to be rare carbonate rock structures formed by microorganisms.
The four students associated with UFV were joined by UFV Geography instructor Olav Lian, and two students linked with NASA Ames Research Center. With the help of University of Northern British Columbia (UNBC) Geography instructor Brian Menounos, and his master’s student, the group used a boat and special equipment to carry out their research.
The expedition’s purpose was to core the lake’s bottom to collect sediment that has accumulated over time.
NASA’s Darlene Lim explained the coring process as similar to putting a straw in a glass of coke, capping the top, and then bringing the straw upwards.
“The coke that’s trapped in the straw is essentially your sample,” she said, adding that in the lake’s case, the sample at the bottom is the oldest, and the top is the youngest.
“So to understand the history of this aquatic system, you can tap into that sediment as a record, or historical book, of what’s happened to this environment over long periods of time,” said Lim. “That’s essentially what we’re interested in — that history of accumulation, and what’s happened surrounding the lake, and also within the lake, over long periods.”
While NASA has been working in the Kelly Lake area since 2004 with the Pavilion Lake Research Project, learning more about the microbialites, Lian has been conducting geology research in the area for nearly 20 years.
The collaboration is important to NASA in determining the region’s history, which they believe will assist them in understanding more about the formations, such as how they’re created and why they are here.
Another key aspect in the collaboration is involving the students.
“We always try to bring as many students with us as we can,” said Lian. “We’re not the type of scientists that like to work in isolation — mentorship of students is incredibly important to us.”
