POTENTIAL PHENOLOGICAL RESPONSES TO ENVIRONMENTAL VARIABILITY AND CHANGE FOR ADÉLIE PENGUINS
Abstract: Phenological changes are touted to be an early indication of species response to environmental change and have been reported for a range of species around the globe. In Antarctica, there is a clear indication of phenological changes for the Adélie penguin (Pygoscelis adeliae) with

A LARGE-SCALE SURVEY OF ADÉLIE PENGUIN BREEDING DISTRIBUTION IN EAST ANTARCTICA
Abstract: A recent gap analysis of knowledge of the breeding distribution of the Adélie penguin across the Australian Antarctic Territory in east Antarctica found that approximately half of the species’ potential breeding habitat had no evidence of ever being searched. With such incomplete

PROPOSAL OF ACOUSTIC SURVEY OF ANTARCTIC KRILL USING FISHING VESSEL
Abstract: Japan is trying to use information obtained through the fishery effectively, and planning an acoustic survey using a commercial krill fishing vessel that enables annual data collection. This proposal focuses on monitoring yearly trend of krill distribution and fishing ground formation.

RESEARCH PLAN AND RESULTS OF PRELIMINARY OBSERVATION ABOUT THE POSSIBILITY OF ANTARCTIC KRILL ESCAPEMENT FROM A TRAWL NET
Abstract: We made a survey plan to observe krill escapement, attached an underwater video camera on a trawl net of a Japanese commercial trawler, and started observation to collect video images of krill passage through the rope and netting parts of the trawl net. Preliminary examination of video

USING AUTOMATED CAMERAS AS A COST-EFFECTIVE MEANS OF EXTENDING LAND-BASED PREDATOR MONITORING
Abstract: Cameras and other optical instruments are increasingly being used as cheap, convenient and reliable tools for surveillance and monitoring. This paper describes (1) the kinds of observations and measurements relevant to CEMP that can be obtained from an automated camera system

SOME POSSIBLE MODIFICATIONS TO CEMP STANDARD METHODS A3A, A3B AND A9 TO ALLOW GREATER FLEXIBILITY IN THE COLLECTION AND INTERPRETATION OF BREEDING POPULATION COUNT DATA
Abstract: At WG-EMM-09 the Working Group noted that the photographic method used in WG-EMM-09/38 could be incorporated as a modification of CEMP Standard Method A3 (penguin breeding population size). This paper reviews aspects of Methods A3a, A3b and related A9 (breeding chronology) in the most

ANALYSIS OF VARIABILITY OF KRILL SIZE AND FISH BY-CATCH IN JAPANESE KRILL FISHERY BASED ON SCIENTIFIC OBSERVER DATA
Abstract: To investigate spatio-temporal variability of krill body length and number of bycatch fish, observer data sets on Japanese krill fishery from 1995 to 2008 were analyzed by using a hierarchical Bayesian model. The model was composed of multistage cluster units (i.e., years, subarea,

ANNUAL CHANGES IN SPECIES COMPOSITION AND ABUNDANCE OF BY-CATCH FISH COLLECTED BY JAPANESE KRILL SCIENTIFIC OBSERVERS IN THE NORTH OF SOUTH GEORGIA (CCAMLR SUBAREA 48.3), DURING AUSTRAL WINTER FROM 2002 TO 2008
Abstract: Species composition and abundance of by-catch fish were analyzed using the fish by-catch samples collected by scientific observers onboard Japanese commercial krill fishing vessels in the north of South Georgia during the austral winter from 2002 to 2008. A total of 19 species belonging

ANTARCTIC PENINSULA DECADAL WINTER TEMPERATURE ANOMALIES AND ANTARCTIC KRILL VARIABILITY IN THE SOUTH ATLANTIC REGION: PRELIMINARY RESULTS
Abstract: The influence of the climate change on krill based Southern Ocean ecosystem is studied intensively last decade. To study the possible connections between Antarctic Peninsula regional climate warming and ecosystem changes the data of Antarctic krill density (KRILLBASE data) and of surface

OPTIMISING THE DESIGN OF LARGE-SCALE GROUND SURVEYS OF ADÉLIE PENGUIN ABUNDANCE USING VIRTUAL SIMULATION IN A GEOGRAPHIC INFORMATION SYSTEM
Abstract: One of the recommendations for future work from the 2008 Predator Survey Workshop was ‘....that alternative census methods for large (penguin) colonies may be helpful. Such methods include the use of satellite imagery and the use of GPS receivers to accurately map colony areas from which
