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.

The Visitor Center will be getting some exciting upgrades this year.  The center will be closed for several weeks sometime late this fall, and then partially open until spring.  Check the website for closure and construction updates before you visit.

Octopus Updates

Our newest octopus is here! While the new male Giant Pacific octopus gets used to his new home the tank will have a few curtains to make it darker.  As he adjusts the curtains will be removed and the lights turned on. We will resume public octopus feedings Thursday, September 21. You can also check out our smaller, native Pacific red octopus currently on exhibit.

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.
