AAA-04北极油气区（一）——巴伦支海石油地质：巴伦支海陆架潜在石油资源评价     

Timothy  R.  Klett  Donald  L.  Gautier  Janet  K.  Pitman  吴峧歧 《海洋地质》2008,24(3)

2008年,美国地质调查局（USGS）完成了对巴货仓支海陆架未发现的、技术上可采的（假定存在海冰）原油、天然气、液态气（总体上被称为石油）的潜在资源评价。如同美国地质调查局环北极油气资源评价（CARA）项目中已评估的其它地方一样,这个地区与许多北极盆地的特点相同,但是与石油相关的资料很少。  相似文献   

A STUDY OF THE SURFACE EMERGING PALAEOCHANNELS ON THE SOUTH COAST PLAIN OF LAIZHOU BAY     

HAN Mei  LI Dao gao  ZHAO Ming hua  JIANG Ai xia 《中国地理科学(英文版)》2000,10(3):245-253

The South Coast Plain of Laizhou Bay adjoins southward the mountains and hills of the Central Shandong Province, extends eastward to the Jiaolai Plain, reaches northward to Laizhou Bay of the Bohai Sea and westward to the Yellow River Delta. All the lower reaches of the Mihe River, the Weihe River and the White wave River are so apt to deposit, burst and move that widespread palaeochannels have taken form,which have rarely been studied(JIA,1985). It is the purpose of this paper to …  相似文献   

STUDY ON FLUXES OF CH4 EMISSION FROM PADDY FIELDS IN CHANGCHUN AREA   总被引：1，自引：0，他引：1  

YAN Min hua  MA Xue hui  WANG De xuan 《中国地理科学(英文版)》2000,(3)

CH4 is a kind of important greenhouse gases in atmosphere. The current atmospheric concentration of CH4 is about 1.7ppmv and is increasing at almost 2％ per year. The sources of CH4 include paddies, wetland and tundra, insects, the digestive tracts of ruminants, coal mining, biomass burning, and the leakage of natural gas. The total input to the atmosphere lies in the range 300－ 550Tg per year. CH4 from paddy fields is about 10％ － 20％ of total source of atmospheric CH4 (DING, 1997). …  相似文献

第四纪地质研究进展     

Graham  R 高莉玲 《海洋地质前沿》1999,(10):6-7

第四纪地质学家们正在继续探寻表示出２．４Ｍａ以来古气候和其它环境变动的沉积记录。在过去１０年,利用加速器质谱仪能够对极小样品作精确的测年,这有助于对一些含碎屑有机质的第四纪沉积记录进行再分析。１　冰心和海洋记录近年来,取自格陵兰的冰心记录和北大西洋的沉积岩心提供了揭示气候变化的地球化学代用资料,反映了急剧的气候波动（通常所说的Ｄａｎｓｇａａｒｄ－Ｏｅｓｃｈｇｅｒ和Ｈｅｉｎｒｉｃｈ事件）,尤其是在冰期及其过渡期。在过去一年,南极冰心测年所取得的进展使得这样的问题再次提出：北半球和南半球气候变化是否…  相似文献
