Coral Reefs and Marine Conservation Insights From Nancy Knowlton

Nancy Knowlton, a marine scientist at the Smithsonian, shares her journey from a general biologist to a dedicated marine biologist, inspired by Dr. Ruth Turner. Her career highlights include studying snapping shrimp, the impact of Hurricane Alan on coral reefs, and the phenomenon of coral bleaching. Nancy emphasizes the importance of conservation and the role of technology in understanding marine ecosystems. She discusses the use of next-generation sequencing to study marine biodiversity and the link between biodiversity and healthy ecosystems. Her career is marked by unexpected discoveries and a passion for marine science.
