1. 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.

2. 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,

3. 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

5. 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

6. 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
