The features of water body of the Tomie Bay is affecting by the inflow of the branch of the warm Tsushima Current. The bottom sediments consist of mostly sandy clastics which are rich in calcium carbonate. More or less muddy sediments are distributed in the restricted area of bay-head and also in he deeper part of eastern entrance of the bay. The bay sediments are classified into three main sediment types according to the grain size distribution, namely, &quat;coarse shell sand"(V), "well-sorted sand" (II) and "silty sand" (IIIa) . There is no distinct relationship between the median diameter of sediments and the depth of sampling station in the Tomie Bay, however, a part of IIIa-type sediments are occurred in deep bottom which has a range in depth from 52 to 59 meters in the eastern entrance of the bay. The average content of organic carbon, total hydrogen and total nitrogen in 27 bottom sediment samples of the Tomie Bay are 0.295, 0.059 and 0.041%, respectively. The C/N ratio ranges from 5.58 to 8.94 with average of 7.04., 長崎大学教育学部自然科学研究報告. vol.33, p.77-91; 1982}, pages = {77--91}, title = {五島列島福江島富江湾の底質とCHN組成}, volume = {33}, year = {1982} }
