ＮＰ９３－２柱样采自南极普里兹湾陆架区域，具有明显的冰海沉积作用特征，受冰川和海洋共同作用。粒度参数、矿物组成、微体古生物和地球化学等资料揭示了该区１２９３７ａ以来的沉积作用特征和沉积环境与气候变动的信息。大约在１０ｋａ，气候波动突然明显回暖，冰筏源碎屑物质增加，晚期还有一个短暂气候波动。 The NP93-2 column sample is collected from the Prydz Bay shelf area of ​​Antarctica and has obvious ice-sea sedimentary characteristics, which are affected by glaciers and oceans. Particle size parameters, mineral composition, microfacies paleontology and geochemistry data reveal the sedimentary characteristics and sedimentary environment and climate change information since 12937a in this area. At about 10 ka, the climate suddenly and obviously warmed up, the detrital matter in the raft source increased, and there was also a brief climate change in the late stage.
