R/V ALPHA HELIX  

Definition

  • The R/V Alpha Helix was designed by Glosten Associates and constructed by J. M. Martinac Shipbuilding Corporation in Tacoma, Washington. It was launched in 1965. The vessel is 133 ft long with a 31-foot beam. It is 433 gross tons based on the International admeasurements system. The National Science Foundation (NSF) is its owner and also funded the vessel’s construction. Scripps Institution of Oceanography, University of California in San Diego, initially operated the vessel under agreement with NSF. The vessel was originally designed to meet the needs of experimental marine biology and was specifically built to conduct this research along the Australian Great Barrier Reef, the Amazon River and Bering Sea. To meet the latter requirement, the vessel’s hull was ice strengthened to allow it to operate around the ice edge and in ice conditions. In 1966 and 1967, the vessel operated in tropical waters of the Great Barrier Reef and Amazon River. In 1968 it proceeded to the Bering Sea for operations. It was soon learned that the vessel lacked the power to penetrate deeply into the ice pack unless escorted by icebreaker. Its shortcomings pointed out the need for a larger more capable icebreaking research and this was the initial impetus to the design of the ARRV. (en)
