Revised research plan for the exploratory fisheries for Dissostichus spp. in Division 58.4.1 in 2014/15
Abstract: The stock sizes for five research blocks (5841_1, 5841_2, 5841_3, 5841_4 and 5841_5) were estimated by the Petersen estimator and the CPUE x seabed analogy method using updated CCAMLR C2 data and reference area sizes. The stock size using the Petersen estimator was generally different

Joint CEP/SC-CAMLR workshop (2016) on climate change and monitoring
Abstract: The Committee on Environmental Protection and SC-CAMLR have endorsed the proposal to hold a second Joint CEP/SC-CAMLR Workshop in 2016. The agreed general scope of the workshop is to identify the effects of climate change that are considered most likely to impact the conservation of the

Comparing two and three frequency dB window identification techniques for estimating Antarctic krill density
Abstract: Three surveys of acoustic data from around South Georgia, collected using a four frequency echosounder (38, 70, 120 and 200 kHz), were used to characterise Antarctic krill. Identification of krill targets was carried out using different permutations of two and three-frequency windows.

An outline of narrowband echosounder survey methods to estimate biomass of Antarctic krill in CCAMLR Division 58.4.1 during 2018/19 season by the Japanese survey vessel, Kaiyo-maru
Abstract: Japanese multidisciplinary survey with a focus on biomass estimation of Antarctic krill will be conducted in CCAMLR Division 58.4.1 during 2018/19. The biomass estimation will be conducted according to the up-to-date CCAMLR standard protocol. The first standardized survey was conducted

A plan for Antarctic krill survey with a scientific broadband echosounder onboard R/V Kaiyo-maru in the CCAMLR Division 58.4.1 during 2018/19 season
Abstract: To investigate the utility of broadband sound for Antarctic krill acoustic surveys, we will conduct echo sampling with a scientific broadband echosounder EK80 (Simrad-Kongsberg) during a dedicated krill survey for CCAMLR Division 58.4.1 during 2018/19 season by Japanese research vessel,

Predicting fishing ground accessibility in the Antarctic Weddell Sea
Abstract: Sea ice is a major constraint of fishery performance in the Southern Ocean seasonal sea ice zone. We use sea ice concentration data from 2002-2017 that cover the wider Weddell Sea to establish statistical models of (i) accessibility, i.e. the probability that a particular area is

Estimating nest-level phenology and reproductive success of colonial seabirds using time-lapse cameras
Abstract: We wish to draw the attention of Members to an online application of the R code published in the attached paper. The web-based app ‘photoR’ (https://jefferson.shinyapps.io/photor2) implements the methods of the paper and provides summary outputs for direct input to CEMP A6b and A9

Impacts of rising sea temperature on krill increase risks for predators in the Scotia Sea
Abstract: Climate change is a threat to marine ecosystems and the services they provide, and reducing fishing pressure is one option for mitigating the overall consequences for marine biota. We used a minimally realistic ecosystem model to examine how projected effects of ocean warming on the

Continuation of multi-Member research on the Dissostichus eleginoides exploratory fishery in 2018/19 in Division 58.4.3a by France and Japan
Abstract: In Division 58.4.3a, since 2012, research fishing has been conducted in the research block by three vessels using longline: “Shinsei Maru No. 3” (Japan), “Saint André” (France) and “Mascareignes III” (France). The first Franco-Japanese exploratory longline fishery research plan for

The winter pack-ice zone provides a sheltered but food-poor habitat for larval Antarctic krill
Abstract: A dominant Antarctic ecological paradigm suggests that winter sea ice is generally the main feeding ground for krill larvae. Observations from our winter cruise to the southwest Atlantic sector of the Southern Ocean contradict this view and present the first evidence that the pack-ice
