The current season (2014/15) is the final one of the first three-season research which began in 2013 in data-poor fisheries. In the present report, the next three-season (2016-18) research plan in Division 58.4.2 was revised using the updated CCAMLR C2 and Observer data.
The stock sizes for a research block (58.4.2_1) were estimated by the Petersen estimator and the CPUE x seabed analogy method using updated CCAMLR C2 data and reference area sizes.
Understanding of the resource structure through clarification of their life history is essential to establish stock assessment and robust stock/ fisheries management of Dissostichus spp. population(s) in data- poor exploratory fisheries. During the second three-season research, we will continue enhanced tagging program, and collection and analysis of biological data including otoliths and gonads to clarify migration route and associated life stages of the fish.
To this end, we propose to follow the current research style in the current research blocks for the second three-season research with the sample sizes estimated following the procedure recommended at the WG-FSA in 2013 in order to maximize the expectation of tag-recapture to the extent possible under the precautionary exploitation rate.
Abstract:
The current season (2014/15) is the final one of the first three-season research which began in 2013 in data-poor fisheries. In the present report, the next three-season (2016-18) research plan in Division 58.4.1 was revised using the updated CCAMLR C2 and Observer data.
The stock sizes for five research blocks (58.4.1_1, 58.4.1_2, 58.4.1_3, 58.4.1_4 and 58.4.1_5) were estimated by the Petersen estimator and the CPUE x seabed analogy method.

Abstract:
In 2014, the Scientific Committee endorsed a proposal from South Africa that the Secretariat be tasked with developing a proposal for funding support from the Global Environment Facility to build capacity among GEF-eligible CCAMLR Member countries to strengthen their participation in CCAMLR (SC-CAMLR-XXXIII, paragraph 10.30). This report updates progress report 1 presented to WG-EMM-15 (WG-EMM-15/15 Rev. 1 – revised text highlighted).
Abstract:
This paper describes the following elements associated with the proposal for a Marine Protected Area in the Ross Sea Region (CCAMLR-XXXIV-29):
a possible procedure for reporting on research and monitoring activities within the proposed Ross Sea Region Marine Protected Area (RSRMPA);
how the Commission might review the extent to which the objectives of the RSRMPA are still relevant and are being achieved; and
the period of designation for the RSRMPA.

Abstract:
Loss of sea-ice, ice shelves and retreat of coastal glaciers around the Antarctic Peninsula in the last few years has exposed new open water, allowing large blooms of phytoplankton to flourish in the newly exposed coastal areas. This new productivity has important consequences as the phytoplankton die and sink to the sea-bed where the carbon is sequestered for thousands of years. This carbon sink acts as a negative feedback to climate change, with an estimated 2.9 million tonnes of carbon drawdown per year on the West Antarctic continental shelf.
Carbon accumulation differs significantly between regions based on specimens collected from the continental shelves of South Georgia, the South Orkney Islands and Bellingshausen, Amundsen and Weddell Seas. The South Orkney Islands are the most productive region per km2 but, at only 4x104 km2, the greatest overall gains are for the larger continental shelves.

Abstract:
The program Integrating Climate and Ecosystem Dynamics, which is a partner program of IMBER and SCAR, will be holding a conference on assessing status and trends of habitats, key species and ecosystems in the Southern Ocean in April 2018. This background paper is an invitation to Members of the SC-CAMLR to participate in working groups on four themes that will be of benefit to SC-CAMLR: (1) Assessments of status and trends in habitats, species and ecosystems, and the causes of change (attribution); (2) Responses of species to changing habitats, including ocean acidification, sea ice and temperature; (3) Modelling and analytical methods to assess status and trends; and (4) Implementation of observing systems to estimate dynamics and change. These themes aim to facilitate contributions of the Antarctic and Southern Ocean marine science community to: the next assessment by the IPCC and recent initiatives to assess status and trends in global ocean ecosystems; the Southern Ocean Observing System; the SCAR Report on Antarctic Climate Change and the Environment; CEP; SC-CAMLR; and IWC-SC.
Abstract:
Part of the remit of WG-SAM includes reviewing and providing advice to WG-FSA and the SC on the experimental design of research plans submitted under CM 21-02, and research proposals submitted under CM 24-01. A total of 34 papers was submitted to WG-SAM-15 for review under this agenda item alone. The large volume of papers, lack of consistent format, lack of clear performance review criteria, and the lack of time available at the meeting made a meaningful review of each plan infeasible. To provide a structure to assist in the review process, WG-SAM requested that proponents compile a self-assessment report card to guide evaluation of the performance of each research plan and/or project. During the review process, several related issues were discussed that are likely to impede or prevent the achievement of the research objectives if not addressed. The purpose of this paper is to provide the structure of the self-assessment to WG-FSA for comment, to characterise some of the issues associated with WG-SAM review of research plans and research proposals, and to suggest a potential mechanism for more streamlined and objective review of progress (to allow standardised, secretariat-generated reports to be produced) for consideration by WG-FSA.
