The Microbes of the Mississippi River – A Rowing Adventure for Science

For the past four months a crew of four rowers and four shore crew members with OAR Northwest, a not-for-profit adventure education organization, have been on a journey of a lifetime on the Mississippi River. After over 100 days of rowing, the crew has traveled from the headwaters of the River in Minnesota to the Gulf of Mexico. They arrived in Baton Rouge on November 16, 2016 and spent a few days visiting LSU and talking to students about their journey.

Just as the state of Louisiana has a special connection with the “Mighty” Mississippi River, the OAR Northwest rowing crew has a special connection with LSU. This is the second OAR Northwest Mississippi River adventure during which rowers have collected water samples for Dr. Cameron Thrash, an assistant professor in the LSU Biological Sciences department. Cameron’s research focuses on relationships between microorganisms and biogeochemical cycles, particularly in marine systems. Thanks to a relationship with the OAR Northwest team that started when founder Jordan Hanssen met Cameron’s family in Washington, and which has developed into an ongoing citizen science project, the Thrash lab is now building a complete microbial “map” of the Mississippi river…
