Some components of uncertainty in the CCAMLR 2000 acoustical survey of krill
Abstract: Quickly studied and quantified were sources of uncertainty in the CCAMLR 2000 ... acoustical estimate of krill abundance in FAO statistical area 48. The variance in system calibration was ... evaluated in relation to the effects of variant water temperature and salinity on sound speed, sound ... absorption, and beam characteristics.
