Rain Blankenship is a senior at the University of California San Diego, majoring in oceanic and atmospheric sciences. His interests include geochemistry, marine chemistry, glaciology, and climate science. Over the summer, Blankenship worked in the lab of Assistant Professor Sarah Aarons, focusing on characterizing the dust deposition to Southern California's San Jacinto Mountains. In Aarons' lab, Blankenship participated in fieldwork that involved collecting dust samples from the collectors placed along the San Jacinto Peak. Over the summer, Blankenship also worked on characterizing the trends in air and possibly the aeolian (relating to or arising from the action of the wind) dust reaching the dust collector sites. He utilized the web-based version of NOAA's HYSPLIT to create backward air parcel trajectories of the air reaching the dust collector sites. These models were then used to identify possible local sources of dust in the surrounding area, including natural and anthropogenic disturbances in terrestrial features such as dry lake beds, farms, and open-pit mines. His favorite part of the SURF Program was hiking up Mt. San Jacinto to collect samples and learn more about all of the interdisciplinary applications available in the fields of Earth science. Beyond research or school-related activities, Blankenship enjoys walking his dogs, listening to classic rock, and has spent far too much time on Netflix during the quarantine. In his senior year, Blankenship looks forward to continuing his undergraduate research under Aarons and her team with the San Jacinto project. Blankenship appreciated that the SURF program provided workshops on graduate school and graduate research opportunities, and said he’s  now more determined than ever to pursue graduate school and earn a PhD.

Rachel Chen is a senior at the University of California San Diego, majoring in marine biology. Her love for marine science stemmed from childhood visits to the Monterey Bay Aquarium. During the SURF program, Chen worked with postdoctoral researcher Elan Portner in Professor Anela Choy’s lab, studying the temporal variability of cephalopods in the diet of the longnose lancetfish (Alepisaurus ferox). Previous studies have analyzed the cephalopod component of A. ferox stomach contents, but cephalopod hard parts (beaks) were excluded. Chen summarized data of individuals identified from beaks and analyzed variability in the most abundant cephalopods found as beaks versus soft tissue specimens over periods of seasons and years. The SURF program allowed Chen to learn about and participate in data analysis and gain research skills she will apply to a senior thesis project in the fall. After graduation, Chen aspires to pursue a PhD in oceanography or marine biology and to share her love for the ocean with others through education.
