Great Lakes Bowl (NOSB)

In June 2022, the national organizers for NOSB decided to put the competition on hiatus while they undergo an administrative transition. Consequently, Michigan Sea Grant does not plan to host a regional Great Lakes Bowl. We will contact teams with any updated information as it becomes available.

What is it?

The National Ocean Sciences Bowl (NOSB) is a national academic competition where teams of high school students compete for the regional and national title. The matches feature quiz-bowl style rounds and challenge questions that test a team’s ocean and Great Lakes knowledge.

The 2022 theme is “Climate Change: Great Lakes Science and Solutions.”

The questions focus on math and science related to ocean and Great Lakes biology, chemistry, geology, physics, technology, history, and economics.

Regional competitions are held throughout the nation in February and March, with the final national competition held between April and early Summer. Michigan Sea Grant hosts the regional Great Lakes Bowl from the University of Michigan.

Where and when?

The NOSB Great Lakes Bowl will be held on Saturday, February 5, 2022. This year, the event will be held virtually.

Who competes?

Teams consisting of four high school students and one alternate compete in question-and-answer matches during the competition.

The competition format is a six-minute buzzer round, then two team challenge questions, followed by another six-minute buzzer round. Team challenge questions require data analysis and synthesis of science and math concepts.

To ensure the safety of our competitors and volunteers, the 2021 Great Lakes Bowl was held virtually. We wanted to ensure that all teams had the same opportunity to showcase their ocean and Great Lakes knowledge, without internet connectivity getting in the way. Thus, the format did not involve head-to-head, direct face-off matchups. Instead, all teams had the opportunity to answer the same number of questions during each round, and their scores determined the winning team. We thank our competitors and volunteers for their patience as we all adjusted to this new, temporary format. The national program organizers will provide information about the 2022 competition format pandemic conditions continue to change. Please direct any questions about the change to

What are the prizes?

The Great Lakes Bowl will award cash prizes, trophies, medals, and other prizes to top finishers.

National prizes have included cruises on aquatic research vessels, visits to research laboratories, computer hardware and software for the winning team’s school, scientific equipment and laboratory supplies, scholarships, endowments, T-shirts, trophies and medals.

How do I compete?

The Great Lakes Bowl is limited to 16 teams. Team entry in the event is approved on a first-come, first-served basis. Teams must submit all required forms to be approved for entry into the event.

How can I volunteer?

Volunteers help the event run smoothly and get to spend time with the next generation of scientists and engineers. No specialized freshwater or marine knowledge is required. Volunteers receive free breakfast, lunch, and event t-shirt.

Note: Because the event involves high school students, the university requires volunteers to pass a background check and complete a brief online training module.
