1. A multi-frequency method for improved accuracy and precision of in situ target strength measurements

   Abstract:  The effectiveness of a split-beam echosounder system to delineate single scatterers and accurately measure in-situ target strengths (TS) is dramatically enhanced (98.2-99.4%) by combining synchronized signals from two or more adjacent split-beam transducers of different frequencies. The

3. Identification of squid echoes in the south Atlantic

   Abstract:  During a research cruise of the British Antarctic Survey ship RRS James Clark Ross in February 1996, a substantial number of the ommastrephid squid, Martialia hyadesi, were caught in a pelagic trawl, near the Antarctic Polar Frontal Zone in CCAMLR Subarea 48.3. This paper describes

5. Important aspects of prey distribution for the formation of foraging areas of chinstrap penguins and Antarctic fur seals at Seal Island

   Abstract:  Variables of prey availability between inshore and slope/offshore foraging areas were compared to evaluate important factors for the formation of foraging areas of Chinstrap penguins (Pygoscelis antarctica) and Antarctic fur seals (Arctocephalus gazella) at Seal Island. Advantages of

6. Krill density, biomass, proportional recruitment and recruitment index in the elephant island region during the period 1977 to 1997

   Abstract:  The Elephant Island long-term data set was updated for krill density and proportional recruitment. Krill biomass (from net sampling surveys) and absolute recruitment are introduced as additional indices for this time series. New survey results of the past two seasons indicate a very

8. Escapement of elephant seal prey in the Heard Island fishery for Dissostichus eleginoides

   Abstract:  The Patagonian toothfish, Dissostichus eleginoides, has been reported as prey of Elephant seals in the Heard Island region. A question was raised at SC-CAMLR-XV concerning what affect the fishery for toothfish in Division 58.5.2 might have on the abundance of the age classes of toothfish

9. A comparison between the estimated density of krill from an acoustic survey with that obtained by scientific nets on the same survey

   Abstract:  This work presents the initial comparative analysis of acoustic and net haul krill density estimates for the RMT 8 oblique (0 to 200m depth) trawls conducted during January-March 1996 as part of a hydroacoustic biomass survey for Antarctic krill in CCAMLR Division 58.4.1. The acoustic
