 note = {In order to clarify the dispersal pattern of Pollen and spores and their transportation mechanism, the surface sediments of Sagami Bay was studied palynologically. In regard to the dispersal and transportation, the following four groups are recognized:\nGroup A: Pollen and spores of this group such as Pinus and Gleichenia have a large buoyancy and are consequently transported by the winds and water currents for a relatively long period. The dispersal pattern of this group is much influenced by hydraulic conditions.\nGroup B: Quercus, Cyclobalanopsis, Alnus and Cryptomeria belong to this group. Although they are same anemophilous flowers as pine, they do not have the same bladders with pine pollen. pollen grains of this group are carried to Sagami Bay by the winds and rivers and deposited within a short period because of a relatively small buoyancy.\nGroup C: Tsuga, Ulmus-Zelkova, NAP(Non Arboreal Pollen) and FS(Fern Spores) of Monolete type belong to this group. Pollen and spores of this group are transported to the bay mainly by the rivers and deposited immediately after the water poured out into the sea.\nGroup D: Keteleeria, Carya and Liquidamber etc. belong to this group. Pollen of this group are reworked fossils from the Pre-Pleistocene sediments. So they are little influenced by the winds in the secondary dispersal process., 紀要論文},
