Concentrations of suspended matter and total particulate fluxes at the Titanic polygon, Northwest Atlantic

Basic parameters of sedimentation environment are considered: the Western Boundary Deep Current that transports sedimentary material and distributes it on the survey area; the nepheloid layer, its features, and the distribution of concentrations and particulate standing crop in it; distribution of horizontal and vertical fluxes of sedimentary material; and bottom sediments and their absolute masses (accumulation rates). Comparison of vertical fluxes of particulate matter and accumulation rates of sediments showed that contemporary fluxes of sedimentary material to the bottom provided distribution of accumulation rates of sediments within the survey area during Holocene.本数据集涵盖沉积环境的基础参数：输送沉积物质并在调查区域内扩散分布的西边界深层流（Western Boundary Deep Current）；雾状层（nepheloid layer）及其特征、雾状层内的浓度与颗粒物现存量（particulate standing crop）分布；沉积物质的水平与垂直通量分布；以及底沉积物及其绝对质量（沉积速率，accumulation rates）。通过对比颗粒物垂直通量与沉积物沉积速率，可发现全新世（Holocene）时期，抵达海底的现代沉积物质通量决定了本次调查区内沉积物沉积速率的空间分布格局。
