3. Krill CPUE standardisation and comparison with acoustic data based on data collected from Chinese fishing vessels in Subarea 48.1

   Abstract:  The usability of CPUE data as Antarctic krill abundance index was a widely discussed ... issue. Many studies suggested the CPUE data should be standardized before using as abundance/biomass ... index. We tried to develop general additive models to standardize the CPUE data collected from Chinese ... fishing vessels during 2009/10-2013/14 seasons. We also compared the CPUE data and acoustic data collected ...

4. Abundance and richness of key Antarctic seafloor fauna correlates with modelled food availability

   Abstract:  Most seafloor communities at depths below the photosynthesis zone rely on food that ... sinks through the water column. However, the nature and strength of this pelagic–benthic coupling and ... its influence on the structure and diversity of seafloor communities is unclear, especially around ... Antarctica where ecological data are sparse. Here we show that the strength of pelagic–benthic coupling along ...

6. Near-shore acoustic surveys for Antarctic krill at South Georgia, January 2004

   Abstract:  Dual frequency (120 and 38 kHz) acoustic surveys were conducted around the Willis ... Islands and off the Barff Peninsula, South Georgia, from a 59 foot yacht in January 2004. The purpose of ... the surveys was to determine krill density near shore, in regions that have not traditionally been ... provisioning chicks ashore were foraging. Despite its relatively small size, the yacht (Golden Fleece) proved ...

9. Uncertainty in echosounder calibrations

   Abstract:  Calibration of echo sounders for fish stock assessment are commonly performed using the ... standard sphere method (Johannesson and Mitson, 1983; Simmonds et al., 1984). To determine the accuracy of ... the method, direct measurements of target strength (TS) were made of three standard spheres (Copper ... (Cu)- 23.0 mm and tungsten carbide (WC)- 33.0 mm and 38.1 mm). At the best case range of 5 m, the TS ...
