Tina Tennessen has a background in radio journalism and loves hearing a good story. She is a science writer, web editor, and a former radio producer. Before joining the National Museum of Natural History team in early 2011, she held the position of Public Affairs Officer at the Smithsonian Environmental Research Center (SERC) in Edgewater, Md. While at SERC, Tina created and edited a news blog called Shorelines and publicized Smithsonian research and educational programs, generating press coverage and public attention for issues such as ocean acidification, hypoxia, invasive species, sea-level rise, shoreline development, and over-fishing. Tina grew up near five of Minnesota's 10,000 lakes and feels fortunate to be working among marine scientists who have dedicated their lives to understanding the underwater realm and the issues that affect it.
