- Abstract
- The paper deals with the seasonal and spectral dependence of volume scattering strength throughout that area of the Gulf of Alaska that is bounded by 150 degrees west longitude, 48 degrees 30' north latitude and the coasts of Canada and Alaska. Two cruises were carried out, in September 1971, and April 1972. Each cruise comprised more than 30 stations which were alternated between midday and midnight, as permitted by weather. Measurements of integrated scattering-strength versus depth were obtained at each station, using the well known technique in which surface-fired 1-lb explosive charge is used in conjunction with a nearby near-surface hydrophone. Selected samples are presented to illustrate the depth behaviour of integrated scattering-strength in the four octave bands between 1.25 and 20.0 kHz. Column scattering strengths taken from such data are exhibited to show the geographical, seasonal, and diurnal variability. TRUNCATED
