Tessa competed at the Quahog Bowl from 2015 to 2018 and now works at the Florida Fish and Wildlife Research Institute as a phytoplankton taxonomist, identifying harmful algal species in Florida waters! Tessa credits her NOSB coach and teacher for encouraging her to study the ocean, saying, "After all, my first science fair project was about phytoplankton thanks to his advice, and now my entire career is about phytoplankton."

Calling all NOSB coaches and educators! In this free, virtual workshop, NSF NCAR & UCAR Science Education partners with the UCAR Center for Ocean Leadership (home of the NOSB) and the Integrated Ocean Observing System (IOOS) Association to share resources and classroom investigations that foster deeper understanding of the ocean's role in our Earth system.

We’ll hear stories of IOOS research and learn how scientists around the world collect data to observe and monitor the ocean. Discover classroom activities from the IOOS K-12 Education Toolkit and UCAR SciEd to help your students explore topics such as coastal hazards, ecosystem changes, and food security. You’ll also learn about an exciting opportunity for your students to join a nationwide community of ocean enthusiasts by competing in the annual National Ocean Sciences Bowl.

Cost: FREE!

The 2027 National Ocean Sciences Bowl (NOSB) competition year theme is: “From Source to Sea: Understanding Marine Debris."

Marine debris is a persistent pollution problem that reaches throughout the entire ocean and the Great Lakes. Students will explore the origins, movement patterns, impacts, solutions, and eventual fate of marine debris through an interdisciplinary and holistic lens.

The theme influences competition questions, professional development webinars, regional enhancement activities, and other special events. Teams can expect at least one theme-related question in every round. Themes are chosen based on input from students, coaches, and volunteers in our post-regional bowl surveys.

Have you ever thought, “I could write a better question than that?” Well, now’s your chance! We are crowdsourcing questions from our amazing ocean science community on a volunteer basis to help augment our competitions. This is a great way to engage with the NOSB on your own time, but please note that to ensure fairness, current participating students and coaches are not allowed to submit questions.

Learn more and submit questions by August 30: https://forms.gle/Cw6FiHHExvpJeKb56

IT'S WORLD OCEAN DAY! Did you know that for many years, the official name used by the United Nations was World Oceans (plural) Day? It was changed to World Ocean (singular) Day
because there is only one ocean with many features. Our global ocean is one living, connected system that powers our climate, sustains life, and unites us all. How are you celebrating the ocean today?

The National Ocean Sciences Bowl (NOSB) would not be possible without the incredible generosity of our sponsors.

In 2026, our sponsors helped support 15 regional competitions, serving 176 teams, 874 brilliant students, and 192 dedicated coaches from 123 schools/affiliations across 26 states. This massive effort was also powered by the in-kind support of 748 volunteers, half of whom were new to the NOSB community this year!

It takes a diverse ecosystem of partners to successfully sustain the NOSB program and its integrated activities year after year. From corporations and government agencies to regional businesses and nonprofits, every level of funding is absolutely vital. Our sponsors are essential pillars of the NOSB community and key to preserving our 25+ year legacy. By investing in these students, our sponsors are directly shaping the future of STEM and ocean stewardship.

To our 2026 sponsors: Thank you for your unwavering belief in this program and its students!

In honor of National Volunteer Week (April 19-25), we want to take a moment to acknowledge our incredible NOSB volunteers! This year, 748 volunteers supported 15 regional competitions across the U.S., ensuring 176 teams of high school students had the opportunity to showcase their ocean science knowledge. Our NOSB volunteers do a lot to make this program happen. From writing and reviewing competition questions to serving as competition officials, volunteers are a keystone species in the NOSB ecosystem. Please join us in saying THANK YOU, VOLUNTEERS!
