1. Calibration of an acoustic echo-integration system in a deep tank, with system gain comparisons over standard sphere material, water temperature and time

   Abstract:  This paper outlines the theory and procedures for calibrating an echo integration acoustic system with a standard sphere. It presents the results of an extensive calibration of a Simrad EK500 scientific echo sounder with a 120 kHz sprit-beam transducer in a refrigerated 10m deep tank.

2. Definition of the problem of estimating fish abundance over an area from acoustic line transect measurements of density

   Abstract:  The problem of acoustic abundance estimation is briefly reviewed. Under proper conditions, fish density can be measured with high accuracy along line transects. Observed variations in fish density consequently reflect biological variations, or inhomogeneity in spatial distribution. The

5. Oceanic condition and zooplankton distribution/ abundance in Bransfield Strait during austral summer 1989/1990

   Abstract:  To delineate zooplankton distribution and abundance in Bransfield Strait, in relation to hydrographic condition, a total of 29 sampling stations was occupied for the CTD casts and plankton towings in a systematic grid from December 29, 1989 to January 7, 1990. Comparisons of temperature
