Paleoceanographic records in the sedimentary cores from the middle Okinawa Trough

Two gravity piston cores (Cores 155 and 180) involved in this study were collected from the middle Okinawa Trough. Stratigraphy of the two cores was divided and classified based on the features of planktonic foraminifera oxygen isotope changes together with depositional sequence,millennium-scale climatic event comparison, carbonate cycles and AMS^14C dating. Some paleoclimatic information contained in sediments of these cores was extracted to discuss the paleoclimatic change rules and the short-time scale events presented in interglacial period. Analysis on the variation of oxygen isotope values in stage two shows that the middle part of the Okinawa Trough may have been affected by fresh water from the Yellow River and the Yangtze River during the Last Glacial Maximum (LGM). The oxygen isotope value oscillating ranges of the cores have verified that the marginal sea has an amplifying effect on climate changes.The δ^13C of benthic foraminifera Uvigerina was lighter in the glacial period than that in the interglacial period, which indicates that the Paleo-Kuroshio‘s main stream moved eastward and its influence area decreased. According to the temperature difference during the “YD” period existing in Core 180 and other data, we can reach the conclusion that the climatic changes in the middle Okinawa Trough area were controlled by global climatic changes, but some regional factors had also considerable influence on the climatechanges. Some results in this paper support Fairbanks‘s point that the “YD” event was a brief stagnation of sea level rising during the global warming up procession. Moreover,the falling of sea level in the glacial period weakened the exchange between the bottom water of the Okinawa Trough and the deep water of the northwestern Pacific Ocean and resulted in low oxygen state of bottom water in this area.These procedures are the reasons for carbonate cycle in the Okinawa Trough area being consistent with the “Atlantic type”carbonate cycle.

温压弹 让“九地之下”面临新威胁

阿富汗战争中,美军首次使用了BLU-118B温压炸弹,有效杀伤了阿富汗东部托拉博拉地区山洞中隐藏的恐怖分子。近年来温压弹发展很快,已成为杀伤洞穴和地下工事内人员的杀手锏武器。温压弹又称“热压弹”、“热钡弹”,主要利用温度和压力效应产生杀伤效果,爆炸时产生的高热和冲击波无孔不入,特别适合于杀伤洞穴、地下工事、建筑物等封闭空间内的人员。温压弹已成为美、俄、英等国当前武器装备发展的重点项目之一,目前已研制和装备了温压炸弹、温压导弹、温压火箭弹等不同类型的温压弹。温压弹基本原理温压弹不是燃料空气弹,它们在工作原理、杀…
