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.

Summer's end  - The Visitor Center switched to its winter schedule starting on Labor Day, Sept. 5. We're open to the public from 10 am to 4 pm Thursdays through Mondays, closed Tuesdays and Wednesdays, until Memorial Day next year.

Note for travelers from the mid-Willamette Valley: A major reconstruction project on Highway 20 between July 16 and Oct 30 will close the highway to traffic from 6:30 p.m. to 4:30 a.m. Sundays through Thursdays between Pioneer Mountain and Eddyville, and may cause travel delays of 20 minutes to two hours during the daylight hours. Consider taking a different route, such as Highway 34 to Waldport or Highway 22/16 to Lincoln City, and bookmark http://us20pme.org/ to check for updates before you travel or to subscribe to email notifications about major delays.

Olson, the giant Pacific octopus

 Welcome Olson., our newest giant Pacific octopus! She just graduated from her quarantine/acclimation period in our animal husbandry wing, and our staff report she is settling in well and "seems to be quite comfortable with all of the strange faces staring at her." The Octocam is back on, but may be dim when we cover the tank to give Olson a chance to rest and get used to her new home.

We've resumed our regular feeding schedule (Thursdays, Saturdays and Mondays at 1 p.m.), with educational presentations around the tank.

We like to keep a second 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.
