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.

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.

Montgomery, a giant Pacific octopus


Montgomery, the giant Pacific octopus that resided in our central tank and has been the star of the popular Octocam, was released into Yaquina Bay the morning of May 13, 2016. 

Giant Pacific octopuses breed only once before they die. When we notice behavior or feeding changes, we start planning the animal's release back to the wild. Montgomery's time at the Visitor Center has been educational and entertaining for the staff, volunteers, visitors and webcam viewers from all over the world.

We are always on the lookout for a new giant Pacific octopus. 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.

While we wait to find a new octopus, we have moved our female wolfeel to the exhibit. Scheduled presentations and feedings will continue. The wolfeel is a very engaging animal and seems to enjoy visitors. Come see her!
