Date: Fri, 25 Mar 1994 20:55:45 GMT Lines: 68 On Thursday, March 24 the Boulder Daily Camera ran a story titled "Plan to Measure Temperature Endangers Marine Mammals" in section C. A team at Scripps Institution of Oceanography at UC San Diego plans to take accurate readings of ocean temperatures to measure global warming. They plan to: "...place loudspeakers on the ocean floor off Big Sur, CA, and blast sounds so loud that they could be heard in New Zealand..." Many scientists are concerned that the noise could deafen whales and other marine animals. The sounds "would be broadcast every four hours for 20 minutes until the year 2004 at a volume much loder than sounds known to frighten whales from their normal migratory route. " "The low rumbling sound would be broadcast at 195 decibels - some 10 million times as load as the 120-decibel level known to disturb some whales," "By comparison, humans can suffer ear damage from 120-decibel noises transmitted through the air" - Lindy Weilgart, a Nova Scotia scientist who studies sperm whale vocalizations. A deafened whale would be unable to navigate or find food. I am appalled that the Scripps Institution would consider such an invasive plan to conduct a measurement. "Sponsors of the project ... downplay any serious harm and say the experiment would yield valuable information about ocean temperatures." Since it is admitted that the impact of this disturbance on whales and other marine life is not known, I would expect the researchers to err on the side of caution, but they seem bent on conducting their research regardless of the potential damage they would inflict. ****************************************************************** The director of the project at Scripps is Dr. Walter Munk at UCSD.
