We describe a spatially and temporally dynamic food-web model of the region surrounding the Western Antarctic Peninsula that can be used to evaluate the potential impacts of various marine protected area (MPA) scenarios. We evaluate four MPA scenarios, including two representing portions of the General Protection Zone presented by the Delegations of Argentina and Chile (SC-CAMLR- XXXVI/18). Our results indicate that protecting regions where krill are anticipated to concentrate in the future could positively affect biomass accumulation of krill and some krill predators. Additionally, protecting areas around Elephant Island seems to benefit chinstrap penguins. We conclude that the most southern areas proposed for protection might positively impact the biomass of krill and krill predators. Protection of these southern areas may be particularly important for ensuring a positive outcome from the D1MPA.

Abstract:
We consider how to advance the development of the concept of an experimental approach to management for the Antarctic krill fishery. We therefore propose a geographic identity matrix and a suitability decision matrix which could help underpin progress towards future implementation. We welcome comments and suggestions to help improve both matrices and their implementation. We also highlight gaps in understanding where we believe new management information is vital and ask the Scientific Committee to consider if these, or other areas of management, are most pressing.
Abstract:
This paper proposes amendments to Conservation Measure (CM) 10-02 and CM 10-09 to strengthen the monitoring and control of transhipments in the Convention Area. The amendments would apply the requirements of CM 10-02 to the carrier vessels of Contracting Parties, establish a CCAMLR Record of Carrier Vessels under CM 10-09 for carrier vessels flagged to non-Contracting Parties, and allow for the monitoring of these vessels as they operate in the Convention Area.
Abstract:
CCAMLR has established a comprehensive set of conservation measures to prevent significant adverse effects of fishing on vulnerable marine ecosystems (VMEs). The United States undertook a spatial analysis to examine whether bottom longline fishing activities took place within VME Risk Areas and in relevant VMEs as a step toward reviewing the effectiveness of relevant conservation measures in protecting VMEs from significant adverse impacts. We found several instances between 2011 and 2017 where longline fishing gear was set inside a VME Risk Area. These findings raise questions about the level of compliance with CCAMLR’s scheme to protect VMEs and VME Risk Areas from bottom fishing impacts. As a result, the United States wishes to provide recommendations increasing the effectiveness of measures to protect VMEs from significant adverse impacts.
Abstract:
The document contains information about two marine scientific research expeditions (PS 117 and PS 118) with the German RV Polarstern, which have some relevance for CCAMLR and which are planned to be carried out in the wider Weddell Sea area south of 60° S in the 2018/19 Antarctic season.
The document also provides advice on how further and more detailed information about these planned expeditions and previous Polarstern cruises can be obtained from the AWI home page (www.awi.de).

Abstract:
The Ukraine submitted to WG SAM 2018 a proposal for a new toothfish research program in Subarea 48.1 (see document WG-SAM-18/11). The research area, which Ukraine intends to use for the new fisheries research program, is located within CCAMLR Subarea 48.1. Detailed analyses of the sea ice concentration and the repeated accessibility of this research area were carried out using the method presented at SAM 2018 (WG-SAM-18/01). The results demonstrate that in the months from January to April (when the survey proposed by Ukraine is to be carried out), difficult sea ice conditions prevail especially the southern parts between 64° S and 65° S of the suggested research area. Here, the mean sea ice concentrations range from 50 to 100 % and mean repeated accessibility is low (between 0 and max. 60 %), even for vessels able to operate under 60 % sea ice concentration.
