Ecologist Pacifica Sommers takes a break from analyzing samples she collected in Antarctica to ponder rivers and water bears in Episode 4. Cryoholes, oceans of suck, Ernest Shackleton's journey, impostor syndrome, tardigrades, microbes and thought piranhas. Pacifica brings her unique perspective on science, life and the outdoors to the River of Suck conversation, to a groove cafe soundtrack of octave mandolin, electric violin, and beatboxing.
