Namibian Marine Internship Amplifies Junior鈥檚 Career Plans

Emma Stange 鈥21 spent her summer south of the equator on the coast of Namibia, a country in South Africa. However, it wasn鈥檛 all sunshine and swimsuits.
A majority of the time, Stange was on a boat with a research team collecting photo identification data of dorsal fins, acoustic recordings, behavioral data and occasionally procuring biopsy samples for genetic information on focus groups of Heaviside dolphins, bottlenose dolphins and humpback whales.
鈥淭his internship has checked off a lot of 鈥榝irsts鈥 for me,鈥 Stange said, listing traveling outside of the U.S. by herself, driving a boat, shooting a crossbow to get a biopsy, disentangling a cape fur seal pup from fishing line, encountering dolphins right under her nose, skydiving and somersaulting down a steep sand dune. 鈥淔or the first time ever, I felt like I was actually a part of something very special and very important to the marine mammal community around the world,鈥 said Stange.
As a research intern with the Namibian Dolphin Project, Stange collected photo, audio and behavioral data that was used to identify individual dolphins to track their social relationships.
鈥淭o collect data yourself and then analyze it to find real-time results and conclusions from your own work is one of the most exhilarating feelings,鈥 she said. 鈥淚t just makes you want to get back out and collect more data to see what else you can learn.鈥澨
鈥淏oth at Pelican Point and Cape Cross we used a microphone and a boom system to record mom and seal pup calls. Our goal was to follow a specific pup or mom around and track their vocal calls to develop a catalog similar to that of the dolphins,鈥 Stange said.
Stange, a marine science-biology and environmental science double major, was in Namibia as a recipient of the Timothy M. Smith Inspiration Through Exploration Award.听
The annual grant, which is given to stimulate international travel and writing among Honors Program participants, has given students a variety of experiences, such as researching coral reefs in the Bahamas, studying mixed-ability dance concepts in England and researching homelessness in Dublin. The award was established to honor the life of Smith, a lawyer by trade, whose true passion was traveling the world.

Namibia was the first African country to protect its environment within its constitution. However, the marine life in Namibia is under-researched. Stange鈥檚 team with the Namibian Dolphin Project was primarily researching marine wildlife in Walvis Bay and the Atlantic Ocean.听
On days when she wasn鈥檛 out on the water, the team conducted weekly land surveys. They would travel to Pelican Point, a Namibian peninsula exposed to both the Atlantic Ocean and Walvis Bay, which is home to a substantial cape fur seal population, black-backed jackals and various seabirds.听
鈥淔or every land survey, our team scanned every seal colony for entanglements in plastic or fishing line by taking systematic photos of the colonies. These photos also helped us to build a data log for the compositions of each seal colony including sex ratio, age ratio, etc., in order to observe fluctuations within and between the years,鈥 Stange said.

Stange was drawn to the work the Namibian Dolphin Project was doing because of her both in high school and while a 澳门六合彩app student.听
Marine mammals rely on their auditory systems to communicate with one another. Noise from shipping traffic, sonar systems and oil drilling can interfere with marine mammals鈥 ability to communicate properly. When shipping sounds are at the same frequency level as their communication, it鈥檚 confusing for these animals, often leading to health complications and beaching.
鈥淭his can be dangerous for the health of marine life, because it effects not only their communication but other activities such as mating and forging for food,鈥 Stange said.
Solving noise pollution can get complicated because politics come into play. Stange is hopeful that through education and awareness, there could be a solution in the future.
鈥淔or me it鈥檚 educating the public, getting them involved and getting them emotionally attached to these marine mammals and seeing these pictures of what happens to them, and hopefully that will spark some change,鈥 said Stange, who is vice president of philanthropy for the 澳门六合彩app Diplomats and lab mentor for biology and biostatistics.
鈥淚 learned how to take myself outside of my comfort zone and experience a new way of life,鈥 Stange said. 鈥淚 have a renewed sense of confidence in myself, and I have realized just how strong of a woman I am.鈥
Encouraged by her internship, which helped her build confidence both personally and academically, Stange hopes to pursue a career as a traveling veterinarian and work with wildlife rehabilitation centers around the world.听
