The Oregon Coast Aquarium is an aquarium in Newport in the US state of Oregon. Opened in 1992, the facility sits on 23 acres (9.3 ha) along Yaquina Bay near the Pacific Ocean. The aquarium was home to Keiko, the orca who starred in the movie Free Willy, from January 1996 until September 9, 1998, when he was shipped to Vestmannaeyjar, Iceland. USA Today considers the Oregon Coast Aquarium world-class and Coastal Living magazine ranks the it among the top ten aquariums in North America.
Newport business leaders proposed building an aquarium beginning in the early 1980s. They proposed a $7 million facility in 1982 as a way to boost the local economy. Two years later they incorporated as a non-profit, and increased fundraising efforts in 1987, collecting $11 million by 1991. Plans to turn 23 acres (9.3 ha) along Yaquina Bay in Newport into a "world class" aquarium were finalized in 1990. The Aquarium was designed by SRG Architects, Portland: BIOS:Inc, of Seattle, and Walker/Macy Landscape Architects, Portland, Oregon.
After early bids were rejected by the aquarium's board of directors, Mountain States Construction was selected to build the first phase for about $12 million in August 1990. Plans for the first phase included construction of a 40,000-square-foot (3,700 m2) building and four acres of outdoor exhibits, with completion expected in spring 1992. Construction began in August 1990 on phase one, with two other phases expected to start three years and eight years later.
On May 23, 1992, the Oregon Coast Aquarium opened with about 5,500 visitors the first day. Those in attendance on the first day included Senator Mark O. Hatfield, Governor Barbara Roberts, and Congressmen Mike Kopetski and Les AuCoin. The opening theme of the aquarium was following the path of a raindrop from the Oregon Coast Range all the way to the Pacific Ocean.
On January 7, 1996, Keiko the killer whale arrived on a United Parcel Service C-130 cargo plane, with freight expenses donated by the company. This move from Reino Aventura, an amusement park in Mexico City, came after fund raising by environmentalists and school children to build a $7.8 million habitat for the movie star in Oregon. Keiko was moved to Iceland in 1998 in an attempt to return him to the wild. For 2012, the aquarium had 450,000 visitors and earned $850,000 on about $7.3 million in revenues.
Exhibits in the main building include four permanent displays: Sandy Shores, Rocky Shores, Coastal Waters, and a changing exhibit area. The first features fish and invertebrates that live either close to shore or in bays such as Yaquina Bay. Progressing, the aquarium displays feature animals further offshore ending in a kelp forest and sea jelly exhibit. Flanking the permanent displays are the changing exhibits.
Secrets of Shipwrecks: Part History. Part Mystery. is the upcoming temporary exhibit that will open on Memorial Day weekend, 2015.
