Welcome to OSU's Hatfield Marine Science Visitor Center!

Oregon State University's Hatfield Marine Science Visitor Center creates a unique, dynamic environment for lifelong exploration and discovery. The Visitor Center encourages adults and children to enjoy marine science as they learn more about the natural world.

Our exhibits, programs and classes demonstrate how scientific research enhances our ability to interpret the natural patterns and forces that shape our world, and equips us to better appreciate, manage and sustain coastal and marine resources.

The Visitor Center also provides opportunities for conducting research on devices, methods and concepts for informal science education that will advance the art of lifelong public education.

Opal, the giant Pacific octopusOctopus Updates

Come to the Visitor Center to meet our exhibit octopus, Opal! Join us for our octopus feeding presentations on Mondays, Thursdays and Saturdays at 1:00 p.m. 

We like to keep a backup octopus in reserve for when the tank's occupant needs a break or is ready to be released back into the ocean to breed. We gladly accept live octopus donations from the fishing community, recreational fishers, tide poolers and beach combers in the area. Contact our aquarist if you have an octopus to donate.
