Zooplankton target strength: volumetric or areal dependence?
MHz and the dependence of these data on animal volume versus cross-sectional area was explored The 420 ... kHz and I MHz data were collected with a dual-beam sonar system and the 200 kHz data with a split-beam ... seawater. The data were compared to both empirical and theoretical models of reduced target strength (TS ... normalized by the square of the animal length) versus ka (the product of wave number and equivalent ...
