6. Supervised and unsupervised (RapidKrill) estimates of krill density from DY098

   Abstract:  We compare supervised, using the interactive software Echoview™, and unsupervised, using python,  processing  of acoustic  data  collected  during  the  UK  cruise  DY098.  The  same  data processing procedures are applied in both methods, and we show that the unsupervised method comes

7. Preliminary biomass estimation of Antarctic krill based on the swarm-based method for CCAMLR Division 58.4.1 in 2018/19 using data obtained by Japanese survey vessel Kaiyo-maru

   Abstract:  Biomass (B 0) of Antarctic krill for CCAMLR Division 58.4.1 in 2018/19 was preliminarily estimated as 4.349 million ton (CV=54.8 %) based on the swam based method using data obtained by Kaiyo-maru. The point estimate was comparable with the estimate in 1996 by BROKE (4.83 million ton

8. Density estimation of Antarctic krill (Euphausia superba) around South Shetland Island and Elephant Island (Subarea 48.1) using two frequencies with 38 and 120 kHz

   Abstract:  The density of Antarctic krill swarm inhabiting the Subarea 48.1, which includes the Elephant Island peripheries and the west and north of the South Shetland Island, was estimated using an acoustics survey. Acoustic data were collected using two frequencies with 38 and 120 kHz from March

9. Biomass results from the International Synoptic Krill Survey in Area 48, 2019

   Abstract:  Results from the International Synoptic Krill Survey in Area 48, 2019, are presented. This survey covered both the strata occupied during the CCAMLR 2000 acoustic survey and the strata that comprise the regular AMLR survey. Acoustic transects (10534 n.mi), oceanographic measurements (253

10. Time series of Antarctic krill estimates around the South Shetland Islands from 2013 to 2019

    Abstract:  Metadata for krill biomass time series obtained by Chinese krill fishing vessel in Subarea 48.1 is submitted with accompanying description of the acoustic survey and data analysis. Distribution of Antarctic krill for the 2013/14 to 2015/16 and the 2017/18 to 2018/19 fishing seasons were
