A new analysis of the topography of the central Andes shows the uplifting of the Earth's second highest continental plateau was driven in part by a huge zone of melted rock in the crust, known as a ma...
Radio echo sounding measurements were collected during two Antarctic expeditions to determine the ice thickness and the sub-glacial morphology of Talos Dome in the region around 72°48'S; 159°06'E (ab...
In the frame of glaciology and palaeoclimate research, Talos Dome (72°48lS; 159°06lE), an ice dome on the East Antarctic plateau, represents the new selected site for a new deep ice core drilling. The...
Numerous observational and modeling studies of ocean circulation surrounding Taiwan have reported occurrences of cold water and doming of isotherms (called the cold dome) that result in the formation ...
An important element of present oceanographic research is the assessment and quantification of uncertainty. These studies are challenging in the coastal ocean due to the wide variety of physical proce...
The "cold dome" off northeastern Taiwan is one of the distinctive oceanic features in the seas surrounding Taiwan. The cold dome is important because persistent upwelling makes the region highly biolo...
In recent decade the edge detection procedure has been of great utility in the modeling and interpretation of self-potential, magnetic and gravity anomalies. This paper applies a precise edge dete...
The exposed Tertiary carbonates of the Dammam Dome present an opportunity to study fractures in outcrops within the oil-producing region of Eastern Saudi Arabia. The study focuses on: 1) the character...
A geomagnetic observatory is a permanent facility where magnetic declination and inclination are recorded in conjunction with the temporal evolution of the magnetic field components. Polar regions are...
We investigated the spatial variability of picocyanobacterial community structure across the Costa Rica Dome(CRD), an offshore upwelling system characterized by high seasonal abundance of Synechococcu...
利用南极中山站至Dome A考察断面上3个自动气象站2005~2007年的观测资料和2008年夏季在中山站附近冰盖获取的湍流观测资料,应用空气动力学方法和涡动相关法计算分析了中山站至Dome A断面上近地层各种湍流参数(感热通量,潜热通量,湍流温度、湿度和速度尺度,地表粗糙度,大气稳定度及动量输送系数)的季节变化、日变化及其空间分布规律.结果表明:感热和潜热均具有明显的季节变化和夏季日变化特征.夏...
利用我国在Dome A 获取的2005~2007 年自动站观测资料, 分析了冰盖近地面3 个高度的气温和近表层4 个深度雪温的季节变化及其差异特征, 并分析了近地面底层逆温及大气稳定状况, 最后对近地面观测气温、10 m 深度雪温以及地面气温的关系作了探讨. 结果表明, Dome A近地面温度变化具有典型的无芯冬季特征, 在长达半年的冬季期间近地面存在强而稳定的逆温. 雪层中季节温度波动的振幅随深...
The Tuztaşı Au-Ag mineralized system was discovered within the Kazdağ dome using BLEG (bulk leach extractable gold) and 180-µm stream sediment geochemical data collected across th...
Dome A(冰穹A)位于东南极冰盖中央, 是南极冰盖最高点. 冰盖演化模式显示, Dome A区域很可能保存了过去超过百万年的地球古气候和古环境记录, 被认为是深冰芯钻孔的理想位置. 冰厚和冰下地形是模式评估冰芯年代尺度和深冰芯钻孔选址的重要依据. 中国第21次和24次南极科学考察(CHINARE 21, 2004/05; CHINARE 24, 2007/08)期间, 车载冰雷达系统被用于Do...
2004/2005年中国第21次南极考察队在南极冰盖最高区域—Dome A(或称Dome Argus)地区, 钻取了一支109.91 m的冰芯. 冰芯CH4浓度测试结果以及粒雪化模型模拟结果一致表明, 该冰芯在约102.0 m处气泡被完全封闭, 并根据粒雪化模型计算气泡被完全封闭处冰的年龄约为4.2 ka. 根据冰芯碎屑样品的氢(δ D)、氧(δ18O)稳定同位素分析资料, 结合东南极冰盖其他内陆...
