Welcome to OSU's Hatfield Marine Science Center 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 life-long public education.

Olson, the giant Pacific octopusOctopus Updates

It is time to say farewell to Olson the octopus!  Olson has been with us since the beginning of summer and delighted thousands of visitors over her stay in the Visitor Center.  We wish her well and are excited for our newest octopus to join the HMSC staff!

Visitor Center octopuses only spend a few months with us before being released to the ocean to grow large and reproduce.

Join us in the Visitor Center for Olson’s last public feeding this Saturday, December 3, 2016 at 1:00pm.

*There will be no public octopus feeding on Monday, December 5 or Thursday, December 8 while our new octopus adjusts to its new home.

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.
