Are we casting the right net? How sampling device influences our understanding of the open ocean
Science is shaped by the tools we use -- even how we visualize the open ocean.

I am a PhD candidate in Biological Oceanography at the University of Hawaiʻi at Mānoa. I use DNA found in the environment (eDNA), like a forensic scientist, to detect deep-sea animals and where they live. When I am not studying the ocean, I am most likely in the ocean surfing or diving along the beautiful coasts of O‘ahu.
