1. Temporal changes in sighting density indices of baleen whales in CCAMLR Subareas 48.1 and 48.2 based on three circumpolar sighting surveys

   Abstract:  This paper examines temporal changes in distribution and sighting density indices of krill-eater baleen whales in Subareas 48.1 and 48.2. This paper was prepared in response to a suggestion in EMM-15 that an analysis of historical cetacean surveys in IWC Area II could provide a context

2. Establishing time-limited Special Areas for Scientific Study in newly exposed marine areas following ice shelf retreat or collapse in Subarea 48.1, Subarea 48.5 and Subarea 88.3 – Clarifications and options to further develop the 2015 proposal

   Abstract:  In 2015 the European Union proposed a draft Conservation Measure (CM) with the aim of promoting and facilitating scientific research in newly exposed marine areas following ice shelf retreat or collapse around the Antarctic Peninsula (CCAMLR-XXXIV/21). The proposed CM would establish

3. Using predators and their prey to characterise the status of the marine ecosystem at South Georgia

   Abstract:  Increased awareness about the present status of marine systems, including those where fisheries target the prey of natural predators, has led to recommendations about how information on the status of marine predators might be used to inform ecosystem-based management approaches. In the

4. Monitoring variability and change in the plankton communities of the Scotia Sea through Continuous Plankton Recorder surveys

   Abstract:  The northern regions of the Scotia Sea demonstrate notable variability in environmental conditions, particularly in the location of the Polar Front. This has a strong influence on patterns of productivity and distribution of plankton, with implications to higher trophic levels, including

6. CEMP data inventory and summary analysis

   Abstract:  The CCAMLR Ecosystem Monitoring Program (CEMP) was established to detect changes in krill-based ecosystems to provide a basis for regulating harvesting of Antarctic living marine resources in accordance with the ‘ecosystem approach’.  This report: summarises CEMP data submissions for the

7. An initial examination of using CPUE as a fishery performance index for the krill fishery

   Abstract:  Early analyses of CPUE in the krill fishery concluded that it was not a useful index of krill abundance. However, understanding the factors effecting the operation of the krill fishery and the extent to which these reflect changes in krill abundance are key elements of developing

8. A spatial analysis of CEMP data in Area 48 to support work on feedback management in the krill fishery

   Abstract:  CEMP data from different sites in Area 48 were used to compare patterns of inter-annual variability as a function of the site location to examine the spatial scale over which CEMP data that have been collected at an individual site reflect changes in the marine ecosystem. Correlations

9. A bioenergetics model for estimating prey consumption by an Adélie penguin population in east Antarctica

   Abstract:  We developed a bioenergetics model to estimate prey consumption by the Adelie penguin. The model predicts prey consumption throughout the breeding season and incorporates uncertainty in model parameters using Monte Carlo simulation. The model was parametised with data obtained from the

10. Krill consumption by Adélie penguins in CCAMLR Divisions 58.4.1 and 58.4.2

    Abstract:  We estimate the total abundance of Adélie penguins foraging in Divisions 58.4.1 and 58.4.2 and provide preliminary estimates of krill consumed by breeding Adélie penguins in these Divisions using a newly developed bio-energetics model.  Our estimate of ~6 million Adélie penguins
