A new approach has been applied to studying marine sedimentation using dispersed sedimentary material in sediment traps compared to the surface layer of bottom sediments. Based on long-term studies of a small sea of the Arctic Ocean, it was possible to establish new sedimentary patterns in the conditions of the Subarctic and Arctic zones. The monthly, seasonal, and long-term dynamics of the main components of fluxes of dispersed sedimentary material have been studied. The marine stage of sedimentation of the main components of dispersed sedimentary material over time is discussed; it is shown that the biogenic component of the flux decreases by an order of magnitude when passing from dispersed to concentrated forms. The average values of the vertical fluxes are calculated: the total and those of the contributions of the main biogenic and terrigenous components per 1 m2 of the bottom and over the entire deep sea area of the White Sea.

白海沉积物的形成:悬浮颗粒物的垂直通量和底部沉积物的绝对质量

与底部沉积物的表层相比,一种新的方法已被用于研究利用沉积物捕集器中分散的沉积物材料进行的海洋沉积。根据对北冰洋小海的长期研究,有可能在亚北极和北极地区的条件下建立新的沉积模式。研究了分散沉积物通量主要成分的每月,季节性和长期动态。讨论了随时间推移而分散的沉积物主要成分在海洋中的沉积阶段;结果表明,当从分散形式转变为浓缩形式时,焊剂的生物成分降低了一个数量级。垂直通量的平均值计算如下:底部的2个,覆盖白海的整个深海区域。
