1. Improvements to the multiple-frequency method for in situ target strength measurements

   Abstract:  Refinements have been made to the multiple-frequency method that was recently developed to improve the accuracy and precision of in-situ target strength (TS) measurements using split-beam echosounders (Demer et al., J. Acoust. Soc. Am. 105(4) 2359:2376 (1999)]. The multiple-frequency

4. Effect of orientation on broadband acoustic scattering of Antarctic krill Euphausia superba: implications for inverting zooplankton spectral acoustic signatures for angle of orientation

   Abstract:  Acoustic scattering experiments involving simultaneous acquisition of broadband echoes and video footage from several Antarctic krill were carried out to determine the effect of animal orientation on echo spectral structure. A novel video analysis technique, applied to extract krill

5. Effects of orientation on acoustic scattering from Antarctic krill at 120 kHz

   Abstract:  Backscattering measurements of 14 live individual Antarctic krill (Euphausia superb a) were made at a frequency of 120 kHz in a chilled insulated tank at the Long Marine Laboratory in Santa Cruz, CA. Individual animals were suspended in front of the transducers, were only loosely

6. Supplement to the krill synoptic survey design in Area 48 (with participation of a Russian scientific research vessel)

   Abstract:  The necessity of synoptic survey covering the South Sandwich Islands that are an integral part of Area 48 is discussed. It is shown that in this case there shall be obtained for the first time for the recent twenty years the material which allows to have an idea of krill simultaneous

7. Fatty acid signature analysis from the milk of Antarctic fur seals and southern elephant seals from South Georgia: implications for diet determination

   Abstract:  Fatty acid signature analysis (FASA) makes use of specific fatty acids, as well as entire profiles, to study dietary relationships at different trophic levels. Previously, FASA has been used in marine ecosystems in which diet determination by more direct methods is difficult and

8. An examination of variance and sample size for female Antarctic fur seal trip durations

   Abstract:  This paper uses power analysis and bootstrap functions to examine the importance of sample size in detecting differences between two years of fur seal trip duration data. Female foraging trip duration for the first six trips to sea for 1997/98 (n = 30) and 1998/99 (n = 31) at Cape

9. The effect of different methodologies used in penguin diet studies at three US AMLR predator research sites: Admiralty Bay, Palmer Station and Cape Shirreff

   Abstract:  Diet studies are a key component of the CCAMLR predator monitoring program as they provide direct assessments of the prey types and amounts of import to predators, which, in turn, are hypothesized to influence variability in related parameters such as breeding success, foraging trip
