 note = {The grain size construction of the bottom sediment on the Prawn Fishing ground was
researched, making use of the samples of bottom sediments collected by the Ekman Verge
bottom sampler at the 195 sampling points, fixed at the off sea of Izumi City, with the
following results obtained.
(1) Generally the bottom sediment of this off sea seems to be divided into the two kinds,
namely, the one consisting of sand, and the other consisting of silty sand. The formations of
the sand parts are noted scatteringly in the following three sections, namely the tideland
section, Western section, and Eastern section. The formations of the silty sand parts are
dispersed widely off the land, while, a part of them is stretched itself in a shape of tongue
towards the tideland section.
(2) Medium diameter shows nearly the value of 1~4φ, sorting is also excellent and this
result suggests that the bottom sediment dispersion in this off sea is of inner-gulf-propensity.
(3) The positions of the average distinguished currents were researched by means of the
value of median diameter, with the obtained assumption that there are two kinds of
distinguished current, the one running from the Western section toward the tideland, and the
other running from the Eastern section towards the tideland., 出水市沖合海域に195点の採泥点を設け,エクマンバージ採泥器により底質試料を採取し粒度組成を求めた。その結果(1) 中央粒径値(Mdφ)は略1~4φの値を示し,淘汰も良好であり,内湾的性格の強い底質分布となっている。(2) 底質は砂質とシルト質砂に概ね2分される。砂質部は干潟域,西部海域及び東部海域に夫々形成されている。シルト質砂部は沖合から干潟域にむかって舌状に南下し張り出している。(3) 中央粒径値の等値曲線図より平均卓越流の存在を検討すると,西部及び東部海域から夫々干潟域にむかう2つの卓越流の存在することが推定され,この流れが当海域におけるクルマエビ類の漁場形成に大きな影響を与えているものと考えられる。},
