Organic geochemical measurements of the lipid fraction, comparing saturated and aromatic hydrocarbons, fatty acids, alcohols and sterols, have been carried out on six sediments cores collected from the Atlantic shelf, slope and the rise areas to evaluate the cross-shelf transport of the organic carbon. The concentration of most of the organic compound classes studied is correlated with the total organic carbon, which decreases from the shelf through slope to the rise. Terrigenous carbon is recognizable even in the slope and rise sediments, but terrestrial influx decreases relative to marine generated lipids in the slope and rise organic matter. We estimate that approximately 50% of the shelf organic matter is exported to the slope. Data of sediment trap material collected at 1200 m from 1250 m water depth are discussed and compared with that of surface sediment from 1280 m water depth (slope). Fluxes for specific organic compound classes have been computed. The fluxes are of the same magnitude as for equatorial North Atlantic trap particulates at comparable water depth, studied by other investigations.

美国新英格兰南部沿海大陆边缘沉积物的有机地球化学-第二部分。脂质。

已经对从大西洋架，斜坡和上升区收集的六个沉积物岩心进行了脂质部分的有机地球化学测量，比较了饱和烃和芳香烃，脂肪酸，醇和甾醇，以评估有机物的跨架运输碳。研究的大多数有机化合物类别的浓度与总有机碳相关，总有机碳从架子通过斜坡到上升逐渐减少。即使在斜坡和上升的沉积物中也可以识别陆源碳，但是相对于斜坡中的海洋产生的脂质和上升的有机质而言，陆运量减少了。我们估计大约有50％的架子有机物被出口到斜坡。讨论了在1250 m水深处1200 m处收集的沉积物捕集材料的数据，并将其与1280 m水深（坡度）中的表面沉积物的数据进行了比较。已计算出特定有机化合物类别的通量。通过其他调查研究，这些通量与可比水深处的赤道北大西洋圈闭微粒的通量大小相同。
