Data file presents information on the variation in sea surface temperatures (SST), as well as geochemical (e.g. stable isotope, calcium carbonate), micropaleontological and grain size data from the Gloria Drift (Northwest Atlantic). The data are obtained from the three marine sediment gravity core sections (AMK-4493, AI-3646 and AI-3415) which were formed during Quaternary period. Dataset contains SST values (winter and summer: 0-50 water layer) and ice-rafted debris (IRD) counts, each in 308 samples; stable isotope data (δO and δC) from 235 samples; calcium carbonate content from 351 samples; relative abundance of polar species of planktonic foraminifera (sinistral) (Ehrenberg) in 51 samples, data of grain size analysis in bulk sediments (123 samples) and carbonate-free sediments (664). These data provide information about conditions of sedimentation at the Gloria Drift area.
数据文件展示了海面温度（SST）的变化信息，以及来自格洛丽亚海流沉积（西北大西洋）的地球化学数据（如稳定同位素、碳酸钙）、微古生物学数据和粒度数据。这些数据取自第四纪形成的三个海洋沉积物重力岩芯剖面（AMK - 4493、AI - 3646和AI - 3415）。数据集包含SST值（冬季和夏季：0 - 50水层）和浮冰碎屑（IRD）计数，各有308个样本；235个样本的稳定同位素数据（δO和δC）；351个样本的碳酸钙含量；51个样本中浮游有孔虫极地物种（左旋）（埃伦贝格）的相对丰度、 bulk沉积物（123个样本）和无碳酸盐沉积物（664个样本）的粒度分析数据。这些数据提供了有关格洛丽亚海流沉积区域沉积条件的信息。
