SG-ASAM-17/01 Подробнее	An outline of the proposed dedicated krill survey for CCAMLR Division 58.4.1 during 2018/19 season by the Japanese survey vessel, Kaiyo-maru H. Murase, K. Abe, T. Ichii and A. Kawabata Резюме: A dedicated krill survey for CCAMLR Division 58.4.1 during 2018/19 season is planned by Japan. No krill biomass has been estimated in the Division since 1996 when Australia carried out BROKE. There are two main objectives of our survey: (1) estimation of krill biomass to update B(0) in the area and (2) oceanographic observations in the area to detect long term changes if any.

SG-ASAM-17/02 Подробнее	Describing krill: swarms or integration intervals? M.J. Cox Резюме: CCAMLR anticipates that acoustic data collected from krill fishing vessels will be incorporated into krill feed back management. Acoustic data collected from fishing vessels may have different characteristics to data collected from research ships. For example, acoustic data collected from fishing vessels may contain seabed aliased echoes and instrument cross-talk.

SG-ASAM-17/03 Подробнее	Evaluation of some processing techniques applied to acoustic recordings from two krill fishing vessels X. Wang, G. Skaret and O.R. Godø Резюме: Acoustic data from krill fishing vessels have the potential to provide useful contributions to assess local krill abundance and distribution, and even as input to the CCAMLR feedback management system under development. The possibility to collect such data from the fleet has been demonstrated through a CCAMLR proof of concept, but processing is in most cases essential before any use of the Read More Представлено (имя): Dr Xinliang Wang (Китай) Утверждено (имя): Dr Xianyong Zhao (Китай) Запросить документ совещания	2, 3
SG-ASAM-17/04 Подробнее	Density and biomass of Antarctic krill around South Shetland Islands using by 2-dB difference method S.-G. Choi, K. Lee and D. An Резюме: The dB-difference and characteristics of krill aggregation inhabiting Subarea 48.1, which includes the Elephant Island peripheries and the west and south of the South Shetland Islands, were estimated to distinguish Antarctic krill, using acoustics. From April 13 to 24, 2016, acoustic data were collected along 24 survey lines using the frequencies 38 and 120 kHz, and midwater trawling was Read More Представлено (имя): Dr Seok-Gwan Choi (Республика Корея) Утверждено (имя): Dr Seok-Gwan Choi (Республика Корея) Запросить документ совещания	3
SG-ASAM-17/P01 Подробнее	A study on calibration for commercial echosounder using bottom backscattering strength in Antarctic S.-G. Choi, H. Lee, K. Lee and J. Lee Резюме: In this study, we calibrated a commercial echosounder (ES70) installed on a krill fishing vessel to use it in estimating biomass of Antarctic krill (Euphausia superba). The method of calibration was to analyze the difference between the bottom backscattering strength of the commercial echosounder (i.e. ES70) and the scientific echosounder (i.e. EK60) at some transects designated by Read More Представлено (имя): Dr Seok-Gwan Choi (Республика Корея) Утверждено (имя): Dr Seok-Gwan Choi (Республика Корея) Публикация: Fisheries Technology in Korea Запросить документ совещания	2
