2. Penguin foraging behavior in relation to the distribution of prey

   Abstract:  The diving behavior of 7 chinstrap penguins (Pygoscelis antarctica) (N=12,171 dives) was measured concurrently with a hydroacoustic assessment of the vertical distribution and abundance of their primary prey, krill (Euphausia superba) in the vicinity of Seal Island, South Shetland

3. Bias in acoustic biomass estimates of Euphausia superba Dana to diel vertical migration

   Abstract:  The diel vertical migration of Antarctic krill (Euphausia superba) can greatly bias the results of qualitative and quantitative hydroacoustic surveys which are conducted with a down-looking sonar and independent of the time of day. To demonstrate and quantify these negative biases on

4. Acoustic estimates of krill biomass in the Elephant Island area: 1981-1993

   Abstract:  Acoustic estimates of krill biomass in the vicinity of Elephant Island for the years 1981-1993 (with the exception of 1982 and 1986) are presented. Estimates for 1981-1991 are based on previous reports adjusted for the recently proposed definition of krill target strength. Biomass

5. Fishes in pelagic catches in the vicinity of the South Shetland Island during the 6th Antarctic expedition of rv Kaiyo Maru, 1990/1991

   Abstract:  During the 6th Antarctic Expedition of R/V Kaiyo Maru (1990/1991), observations on the occurrence and abundance of fishes in a total of 102 pelagic hauls for the Antarctic krill were made. Of the 102 net hauls, a total of 104 fishes belonging to 4 families and 16 species were captured in

10. Cross-sectional structure and validation of the timing of annulus formation in otoliths of the Antarctic fish Notothenia coriiceps Richardson (Nototheniidae)

    Abstract:  To validate the timing of annuli in otoliths of immature Notothenia coriiceps Richardson. a time-series of samples were taken over a complete year. Light and scanning electron microscopy (SEM) techniques were used to examine the structure of sectioned otoliths. Six growth regions were
