The NOSB is an academic competition and program that addresses a national gap in environmental and earth sciences in public education by introducing high school students to and engaging them in ocean science, preparing them for ocean science-related and other STEM careers, and helping them become knowledgeable community members and environmental stewards.

All states are eligible to compete. Contact us to learn more.

Regional NOSB competitions are held at universities, research institutions, laboratories, science centers, and aquaria across the country. Each year, up to 2,000 students from 350 high schools and 1,500 volunteers participate in the program.

2025-2026 Competition Year Information

We’re actively updating this page as regional coordinators confirm their plans. Unfortunately, due to challenges at both the national and regional levels, some regional competitions may not be held this year. At this time, a national Finals competition is also unlikely. If a Finals does take place, it will be held virtually. Please know that NOSB staff and regional coordinators care deeply about providing opportunities for students, and the decision not to hold a competition is never made lightly. Check back here regularly for updates, and be sure to sign up for our newsletter to stay connected and receive the latest program information.

Teams of high school students that do not have a regional bowl happening near them have two options:

  • Coaches can email the National Office with a request to attend another regional bowl in-person.
  • Teams can compete head-to-head virtually on Zoom in the Virtual Sponge Bowl. Coaches can contact the Regional Coordinator to learn more after reviewing the Information for Teams and Competition Rules to ensure eligibility.

Virtual Sponge Bowl

Competition Date:  March 21 and 22, 2026
Location: Virtual
Hosted by: People Making a Difference (PMD). Visit the website for participant information.

Introducing the 2025 NOSB National Champions: Thomas Jefferson High School for Science and Technology

The Center for Ocean Leadership (COL) is thrilled to announce the winners of the highly anticipated 2025 virtual National Ocean Sciences Bowl (NOSB) Finals Competition, which took place this past weekend in an exciting display of ocean science knowledge, teamwork, and passion for our blue planet. An interdisciplinary ocean science education program of COL, the NOSB has tested students’ knowledge of ocean-related topics through buzzer-style multiple choice and longer, critical thinking-based questions for 27 years.
