| 内容記述 | Kaiyo-mayu, the research vessel of the fishery agency of Japan, made her second cruise of 1968 to the Pacific coast of South America, with the purpose of exploitations of trawl fishery grounds in that sea area and the vicinity. During this cruise, the present author engaged in research of the bottom sediments collected by some dredging equipments for analysis of the environmental factors of the inhabiting fishes in those sea areas, and in this report is outlined the distribution of Foraminifera as well as the geological characteristics at every researching station. 1. The quantity of Foraminifera were more along the Peru coast than elsewhere, and there was a tendency to be distributed on the bottom from the shallow to deep areas according to the characters of adaptation of each species. In general, geographical differentiation of their community was not found in the sea areas investigated during this cruise. 2. The bottom of Mancora bank, north of Peru, consisted of basalt (genbugan in Japanese) and mudstone (deigan). The partly consolidated sediment which occupied the upper part of the continental slope was sandy-shale (sashitsu-sirutogan). Pebbles found near the Chiloe island off Chile consisted of granite (kakogan), quartzite (keigan), andesite (anzangan) and slate (nenbangan). 3. According to Sato's classification of size of the sand particles (1959), the sands of those areas belong to the III1 . ll1 . IlI 2 sand type groups. The most characteristic sediment was the mud that had an odor of hydrogen sulfide; this was distributed in the area between 10°-36° S in latitude. 4. As far as the present studies of the bottom sediments are concerned, the possibility of exploiting of trawl fishery in these sea areas were less than in the areas of the adjacent sea of Japan. | |||||

| 内容記述 | ペルー·チリ沿海の底曳漁場調査(エメラルド調査)で採集した海底の堆積物について一般的特性を明らかにした.1. 有孔虫はペルー海域でとくに多く生息している·浅海のものと深海のものとからなる分布であると思われるが,調査全域を概観すると,地理的な群集の分化はとくに大きいとは思われない.2. ベルー北部のマソコラバソクは玄武岩と泥岩からなっている.また大陸傾斜面上部にある半ば凝固状の泥板は砂質シルト岩である.チリのチロエ島付近の海底で円礫がみられるが,これは花崗閃緑岩·硅岩·粘板岩·安山岩等である.3. 砂泥は佐藤(1959b)の分類によると Ⅲ1·I1·Ⅲ2 sand type を示すことが多い.最も特徴的なのは,10°~36°Sの大陸棚上にみられる硫化水素臭をもつ黒色を帯びた泥の分布である.4. 底曳漁場の底質としては日本近海の以東底曳漁場より操業上の条件が悪いと思われる. | |||||
