The speed of longitudinal sound waves in Antarctic krill has been measured by the time‐of‐flight method. The result of 17 separate measurement series on different assemblages of living krill is that the animal’s sound speed exceeds that of seawater at the same temperature by 2.79±0.24%. The mean lengths vary from 29.4 to 38.9 mm, with overall mean 32.2 and s.d. 2.5 mm. The corresponding density of krill of mean length 31 mm is 1.0647±0.0069 g/cm3 . Measurement temperatures varied from 5.3 to 12.1°C; corresponding salinities varied from 32.5 to 33.87 ppt, which also represent the ambient state. The ambient sea temperature was 2.0±0.3°C.

Distinctions in sound patterns of calls by killer whales (Orcinus Orca) from analysis of computer sound features
Watkins, William A.; Daher, Mary Ann; DiMarzio, Nancy A.; Reppucci, Gina (Woods Hole Oceanographic Institution, 1998-03)Calls of killer whales, Orcinus orca, were analyzed using computed sound features to classify sound patterns and identify call similarties. Calls were classified and separated according to the podfamily group within clans ... -
Differences between sound scattering by weakly scattering spheres and finite-length cylinders with applications to sound scattering by zooplankton
Stanton, Timothy K.; Wiebe, Peter H.; Chu, Dezhang (Acoustical Society of America, 1998-01)A modeling study was conducted to determine the conditions under which fluidlike zooplankton of the same volume but different shapes (spherical/cylindrical) have similar or dramatically different scattering properties. ... -
Hearing abilities and sound reception of broadband sounds in an adult Risso’s dolphin (Grampus griseus )
Mooney, T. Aran; Yang, Wei-Cheng; Yu, Hsin-Yi; Ketten, Darlene R.; Jen, I-Fan (2015-04)While odontocetes do not have an external pinna that guides sound to the middle ear, they are considered to receive sound through specialized regions of the head and lower jaw. Yet odontocetes differ in the shape of the ...
