Student spotlight: Sidney Yazzie

Sidney Yazzie and her sister Maddy are enrolled at Prince William Sound College (PWSC) for their second semester. Originally from Arizona, Sidney is experiencing Alaska for the first time and is in awe of its natural beauty. She has transitioned from the Marine Natural Resources Technology (MNRT) program to the Natural Resource Technology (NRT) program.

Through her coursework and research projects, Sidney has developed a strong interest in ocean and marine science, particularly seaweed and ocean acidification.

Sidney is involved in two research projects: one focused on environmental DNA (eDNA) sampling and preservation methods and the other on monitoring ocean acidification. Both projects are conducted in collaboration with the Alutiiq Pride Marine Institute (APMI).

Environmental DNA (eDNA) is a non-invasive method that allows scientists to study ecosystem biodiversity and changes. This technique helps detect rare, elusive, or endangered species. Additionally, eDNA can help monitor invasive species, assess the health of aquatic ecosystems, and identify harmful algal blooms. Overall, environmental DNA serves as an effective tool for conservation efforts. Sidney's sampling involves deploying customized devices in the Valdez Boat Harbor to collect water samples over 24 to 48 hours, which are then preserved and analyzed.

Ocean acidification is a long-term process in which the ocean absorbs carbon dioxide from the atmosphere, decreasing its pH and carbonate ion concentration. This phenomenon can harm marine life and ecosystems and is sometimes called the "osteoporosis of the sea."

Sidney's ocean acidification project involves biweekly plankton tows and the collection of blue mussel samples, which are sent to APMI for analysis.

Sidney is considering staying in Alaska for the next semester and potentially for the summer to continue her education and research opportunities.
