Volcano May Change Research Ship's Plans
Research plans may have to be changed somewhat for Stanford University's research vessel, the 135-foot schooner, Te Vega, because of recent volcanic eruptions in the Galapagos Islands. Just back from the Galapagos, the Te Vega has been in home port in Monterey tor two weeks undergoing minor repairs and refitting for her nineteenth expedition under National Science Foundation sponsorship. She is scheduled to sail for the islands again on Friday, June 28. Since the ship's return, news has come that Isla Isabels, one of the five larger islands of the Galapagos group, has been spouting hot lava. Prof. Malvern Gilmartin of Stanford's Hopkins Marine Station, director of the Te Vega program, said he does not expect the eruptions will cause any drastic change in plans, however. While the eruptions may prevent investigations in Isla Isabela, the other major islands should not be seriously affected. There are also more than a dozen smaller islands in the group. Three coeds are among the 11 graduate students in biology who have won berths on Expedition 19. Dr. W. Jan Newhouse of the University of Hawaii will head a faculty of five planning to study marine life in the vicinity of the islands. The ship will stop at Acapulco en route to the Galapagos, and the expedition is scheduled to end Sept. 11 at Guayaquil, Ecuador. A professional captain and crew of 15 sail the steelhulled schooner, permitting research and teaching to proceed full time.
