National Ocean-Science Competition Makes a Splash in Colorado
This Earth Day weekend, over 100 students from 20+ U.S. states, including Alaska and Hawaii, will chart their course to the University of Colorado Boulder, to match wits in the National Ocean Sciences Bowl. The student finalists will put their knowledge to the test—expertly answering Jeopardy-style trivia questions on topics including marine chemistry, policy, biology, and more. CIRES will host the competition here in Boulder—it’s the first time the nationals have been held in a fully landlocked state.
