The acoustic component of this survey was conducted using a scientific echosounder operating at 38 and 70 kHz to estimate the distribution and density of Antarctic krill (Euphausia superba) and ice krill (E. crystallorophias). In addition, the relationship between the vertical distribution of Antarctic krill and the water temperature structure along the 140°E meridian was investigated. Antarctic krill were distributed in the waters of the continental slope at 65–66°S and the maximum value of the mean areal density ρ in 1 nautical mile (nmi) intervals was 4344 inds. m−2. Ice krill were distributed in the neritic waters of the continental shelf to the south of the 66°S and the maximum ρ in 1 nmi intervals was 23,669 inds. m−2. Along the 140°E meridian, Antarctic krill were mainly distributed at the water temperatures below 0.5 °C. Although they were mostly distributed shallower than approximately 100 m, dense aggregations at approximately 180–200 m were also observed, which coincided with a depression of the water temperature structure.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Collaborative East Antarctic Marine

kHzの計量魚群探知機による音響調査を実施した。特に140°Eにおいては，ナンキョクオキアミの鉛直分布と水温構造の関係を調べた。ナンキョクオキアミは65～66°Sの陸棚斜面上に分布し，1マイル毎の平均密度は最大で4,344 inds. m-2であった。コオリオキアミは66°S以南の陸棚上に分布し，平均密度は最大で23,669 inds. m-2であった。140°Eにおいては，ナンキョクオキアミは0.5°Cより低い水温帯に分布していた。そのほとんどは約100 m以浅に分布していたが，約180～200
