3. Water mass distribution and circulation west of the Antarctic peninsula and including Bransfield Strait

   Abstract:  Historical hydrographic data from Bransfield Strait and the region west of the Antarctic Peninsula were analyzed to provide a description of water mass distributions and circulation patterns. Circumpolar Deep Water (CDW), which is characterized by temperatures above 1.0°C, salinities of

4. Dynamic model of krill Euphausia superba swarm

   Abstract:  During the Italian Antarctic Expeditions to the Ross Sea, in the years 1989- 1994, using the 38 and 120 kHz BioSonics dual-beam hydroacoustic system, numerous swarms of krill Euphausia superba Dana were registered. Analysis of their physical parameters was carried out. It is known that

5. Environment-krill interactions in the South Georgia marine system

   Abstract:  Interrelations between environmental variables, and between those variables and krill CPUE are discussed. Some reliable relationships is revealed. Based on those of krill abundance interannual fluctuations relationship hypothesis is formulated. Author(s):  Symon, C., Fedoulov, P.P.,

6. Uncertainty in standard sphere calibrations

   Abstract:  In fisheries acoustics, the standard sphere method of echosounder calibration is most commonly used (Johannesson and Mitson, 1983; Simmonds et al., 1984). To investigate the uncertainty in the method, a series of experiments were conducted in a deep tank (Demer and Hewitt, 1993). Results

7. Acoustic survey design to estimate krill biomass in Subareas 48.1, 48.2 and 48.3

   Abstract:  The Scientific Committee has requested advice on the feasibility of conducting a synoptic survey of krill biomass in Statistical Area 48. Example calculations are presented for estimating the amount of survey effort required to achieve a target level of precision using a stratified

8. Uncertainty in acoustic surveys of Antarctic krill

   Abstract:  Studied were four primary sources of uncertainty in krill density estimates from acoustic surveys. The variance in system calibration with a standard sphere was evaluated in relation to sphere material and diameter, water temperature, and pulse length (Demer and Hewitt, 1992).

10. An acoustic estimation of krill densities to the north of South Georgia in January 1994

    Abstract:  Dual frequency (38 and 120 kHz) acoustic surveys were carried out in two regions along the northern coast of South Georgia from RRS lames Clark Ross during January 1994. Difference in signal strength between the two frequencies (δMVBS = MVBS 120 kHz- MVBS 38 kHz) was used to discriminate
