1. PROPOSED APPROACH FOR THE IDENTIFICATION OF IMPORTANT MARINE AREAS FOR CONSERVATION: USING ‘MARXAN’ SOFTWARE TO SUPPORT SYSTEMATIC CONSERVATION PLANNING

   Abstract:  We provide a worked example of how a systematic conservation planning methodology (Margules & Pressey, 2000) might be used to identify important areas for conservation of biodiversity in the pelagic environment, using Subarea 48.2 (South Orkney Islands) as a pilot study area. The aim

2. Flexible foraging strategies of gentoo penguins help buffer the impacts of inter-annual changes in prey availability

   Abstract:  Gentoo penguins Pygoscelis papua show considerable plasticity in their diet, diving and foraging behaviors among colonies; we expected that they might exhibit similar variability over time, at a single site, since flexible foraging habits would provide a buffer against changes in prey

3. DOWN-SCALING FOOSA TO MODEL THE ADMIRALTY BAY PYGOSCELID PENGUIN COLONIES: A WORK IN PROGRESS

   Abstract:  We apply Foosa at the scale of interactions among the 3 breeding penguin colonies, krill, and environmental variability at the long-term research site in Admiralty Bay, King George Island. This work-in-progress serves 2 purposes: 1) to use historical data to estimate parameters in a

4. PROPOSAL FOR A JOINT CEP/SC-CAMLR WORKSHOP IN 2009

   Abstract:  At its meeting in 2007 CCAMLR endorsed the proposal from the Scientific Committee for a joint CEP/SC-CAMLR workshop. The CEP discussed this at its meeting in June 2008 and suggested a theme of ‘Opportunities for collaboration and practical cooperation between the CEP and SC-CAMLR’. The

5. PRELIMINARY ESTIMATION OF PENGUIN BREEDING ABUNDANCE AT SPATIAL-SCALES OF RELEVANCE TO CCAMLR: INCORPORATING UNCERTAINTY IN COUNT DATA

   Abstract:  One recommendation from the Predator Survey workshop was the undertaking of some immediate inter-sessional work to be reported to WG-EMM-08. The work to be undertaken included preliminary estimation of SSMU-specific gentoo and Adélie breeding abundance in Area 48, and similar analyses of

6. NET-BASED VERIFICATION OF ACOUSTIC TECHNIQUES USED TO IDENTIFY ANTARCTIC KRILL

   Abstract:  We validate the acoustic target classification protocols developed for the Stochastic Distorted-Wave Born Approximation (SDWBA) model using three frequency acoustic data and concurrent net hauls that were collected during two cruises to the South Georgia region in 1996. For each krill

7. PROPERTIES OF KRILL DISTRIBUTION IN PELAGIC AND COASTAL SSMUs OF THE SOUTH ORKNEY ISLANDS SUBAREA ACCORDING TO THE DATA OF SCIENTIFIC OBSERVATIONS AND FISHERY

   Abstract:  In this paper the krill spatial distribution in the in coastal and pelagic SSMUs of the Subarea 48.2 depending on oceanological factors is considered. Estimates of krill biomass and aggregation characteristics, and krill transport factors according to different modifications of Antarctic

8. Measurements of sound-speed and density contrasts of Antarctic krill (Euphausia superba) on board RV Kaiyo Maru

   Abstract:  In order to calculate the target strength of Antarctic krill (Euphausia superba) using an acoustical scattering model, information on size, morphology, orientation, sound–speed and mass-density contrasts between the animal and the surrounding water are required. Sound-speed and mass

9. RAPID WARMING OF THE OCEAN AROUND SOUTH GEORGIA,SOUTHERN OCEAN, DURING THE 20TH CENTURY: FORCINGS, CHARACTERISTICS AND IMPLICATIONS FOR LOWER TROPHIC LEVELS

   Abstract:  The Southern Ocean is known to have warmed considerably during the second half of the 20th century but there are few locations with data before the 1950s. In addition, assessments of change in this region are hampered by the strong seasonal bias in sampling, with the vast majority of
