冰期

The evolution of tides and tidal currents on the continental shelves of the Bohai Sea, Yellow Sea and East China Sea has deeply influenced the sediment transport and deposition as well as the formation, distribution and evolution of sea bottom topography since the Last Deglaciation.

摘要末次盛冰期结束、海侵开始后渤、黄、东海陆架潮汐、潮流的演变对该区泥沙的输运与沉积，以及海底地貌的形成、分布以及演变等具有深刻影响。

The project team has taken loess, lacustrine and peat sediments and tree ring as the research carrier, a systematic study has been carried on the warm phases of the different period (60-25 ka, last deglaciation, Holocene, the recent e few hundred years) and the last interglaciation on the basis of the extensive field investigation and laboratory analysis.

项目组以黄土、湖沼和树轮等沉积物为研究载体，经过大量的野外考察和实验室分析测试，对我国半干旱带末次间冰期和距今六万年以来不同时间段的温暖期（6万年到2.5万年、末次冰消期、全新世、最近几百年）进行了系统的研究，取得了一批重要的阶段性成果，确认了东亚季风气候和温暖期的不稳定性特征。

The input of light isotope enriched terrestrial carbon causes atmospheric δ^13C to drop by about 0.3‰ at deglaciation,followed by a rapid rise towards a high interglacial value in response to oceanic warming and regrowth on land.

在间冰期，劳伦和芬诺斯堪的亚冰盖融化的大量融溶水注入北大西洋，这种融溶水持续以大约0.1 Sv有规律的释放，已对位于北大西洋大洋传输带循环的"Achmes Heel"构成了威胁。

ABP. Sedimentation rate is very low on the whole core and shows three apparent variations at three phases:① A comparatively high SR during marine isotope stage 3 (MIS3) and LGM, about 7.3 and 14cm/ka respectively;② A very low SR of 1.5cm/ka during the last deglaciation, which is different from the deeper Okinawa Trough with higher SR during the last deglaciation than the last glaciation;③ A negligible sediment accumulation since 6.4 cal.

DOC-42孔沉积速率整体较低，呈明显的阶段性变化：在氧同位素3期和LGM期间沉积速率相对较大，分别为7.3和14cm/ka；末次冰消期以来的沉积速率则显著降低，与冲绳海槽冰后期沉积速率高于末次冰期明显不同；自约6.4 cal。

The river patterns of the study area were analyzed by the latest channel pattern discrimination in the last glacial maximum and deglaciation of the Late Pleistocene. The hydrology, sediment, environment parameters of the ancient channel in the study area, width-depth ratio F =22.22, suspended sediment concentration M =10.10%, channel curvature P =1.52, meander wavelength L =

然后应用最新河型判别方法，分析判别晚更新世末次盛冰期和冰消期研究区埋藏古河道的河流类型为辫状型；并分析得到研究区古河道的宽深比（ F ＝22.22）、悬移质含量（ M ＝10.10％）、河道弯曲率（ P ＝1.52）、河曲波长（ L ＝1 647 m）等古水文泥沙环境参数分类指标。

The results show the mineral taxa, morphological characteristics and the high contents of magnetite and dens revealed the multi-sources and near-derived features of the loess-like loess in Zhifu Island, and the main sources of loess are seabed plain, diluvium and residual sediments in the last glacial period, while thin sediments from Northwest inland desert are rare.

结果表明，芝罘岛黄土状黄土矿物种类、矿物形态特征、磁铁矿和岩屑的高含量等都揭示了黄土来源的多源性和近源性，末次冰期时的海底平原沉积物以及洪积、残积物是芝罘岛黄土状黄土的重要物源，而西北内陆沙漠吹来的细颗粒物质相对较少。

On the eastern plateau platform, haplotype A was commonly fixed in the current disjunct populations, suggesting a common postglacial recolonization and a following founder effect.

我们的研究结果表明祁连圆柏在冰期可能存在多个避难所，瓶颈效应和奠基者效臆造成了这些居群现在的遗传多样性分布式样。

Microfossil assemblages and foraminifer isotopes from the upper part of ODP Hole 807A on the Ontong Java plateau were studied to provide evidence for discussing Late Quaternary productivity variations with glacial cycles in the western equatorial Pacific.

通过研究翁通－爪哇海台ODP 807A孔顶部岩心微体古生物和有孔虫同位素的变化，探讨冰期旋回中赤道西太平洋晚第四纪古生产力的变化。

Almost all of the foraminifera are present in the last glacial loess, but the distribution patterns of foraminifera show significant temporal changes.

冰期黄土中有孔虫化石的这种差别，说明同样是海平面下降，但不同时期海平面下降时可能具有巨大的差别。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
