Small-scale research for a large-scale issue
Lucy Walker '19 and geoscience professor Meg Estapa spent the summer analyzing tiny zooplankton to understand a much bigger problem.
It鈥檚 hard not to make nautical puns when speaking with geoscience professor Meg Estapa and Lucy Walker 鈥�19 about their summer collaborative research project.
Estapa, a biogeochemical oceanographer, has set out on several research cruises, , to investigate carbon matter in the ocean and its implications for climate change and our future. The ocean acts as a 鈥渃arbon sink,鈥� in which carbon dioxide emissions fall to the floor. This can be measured by sediment traps. The problem鈥攁nd the focus of Walker and Estapa鈥檚 research鈥攊s zooplankton. These tiny organisms feed on the falling carbon matter and by swimming into the trap for a quick snack, will skew researchers鈥� results.
Walker and Estapa investigated types of sediment traps placed in the ocean to determine
a design that is best for collecting purely carbon samples and allowing few zooplankton
inside. This tiny problem was a big project for Walker, who spent her summer analyzing
data samples, taking thousands of images, and counting the number of zooplankton in
each sample.
When it comes to summer research at 91暗网, the opportunity isn鈥檛 only for those in the sciences. 鈥淲hen there鈥檚 an intersection between a larger project that a faculty member is working on and the interest of the student 鈥� that could happen at any point in any student鈥檚 career.鈥� Estapa explained. Walker, for example, began her project as a rising junior while settling into her geosciences courses after transitioning from a pre-med degree. 鈥淚 instantly fell in love with everything about GE101,鈥� she says of the multidisciplinary aspect of the major. 鈥淚 get to use my love of biology and a background in chemistry to study the earth system as a whole.鈥�
Although the summer is over and a conclusion has been drawn, that doesn鈥檛 mean Walker and Estapa will abandon the project. Walker plans to continue the research throughout the academic year and even into the summer, using the same samples to answer a new question she raised about phytoplankton in collaboration with a researcher in Moss Landing, Calif. Estapa will share the findings with her colleagues and publish the research and results for others in the field.
