Two Norwegian researchers examine the forces alternatively driving and hindering offshore hydrocarbon development in the Russian sector of the Barents Sea. The paper describes exploration activities beginning during the Soviet period and extending to the present, the status of the major development projects financed in part with foreign capital, and conflicting regional and central government interests involved in such development. Coverage includes the emergence of Rosshelf, an oil/gas conglomerate formed to facilitate defense conversion activities of major naval shipyards. Critical to analysis of the projects' potential is assessment of alternative gas supplies and energy development strategies.

The media team on the 2004 Deep Gulf Wrecks mission fulfilled three video-related functions: documentation, preservation,
and outreach. Instead of looking at the media team as witnesses to the scientific events or as video tourists, the mission
leadership integrated the video, backup, and Internet work into the scientific process carried out in the Gulf of Mexico.
While not the first time this kind of cooperation has occurred in deep sea exploration work, the extent of media-scientific
collaboration was exceptional in an age of soundbites and formulaic scientific filmmaking. The key strategic and technical
lessons learned from the mission are summarized. 相似文献

AbstractThe authors review expected water requirements within the Volga-Caspian basin for industry, agriculture, fisheries and municipal uses and plans for the diversion of the streams of northern European Russia to the south to support the level of the Caspian Sea. They suggest that the diversion of part of the flow of the northern streams and isolation of the natural evaporation basin of the Kara-Bogaz-Gol will be sufficient to maintain the Caspian Sea level at ?28 meters. Previous articles on the Caspian problem appeared in Soviet Geography, September 1961, January 1962, and June 1963. 相似文献

"金马碧鸡"是我国西南地区重要的地方传说。关于"金马碧鸡"传说的由来,以往研究者提出的自然现象说、矿产说虽有合理之处,但忽略了地理环境和西汉社会动因对该传说的塑造作用,未能解析这一传说的形成轨迹。笔者从多维贯通的视角出发,研究认为:云南大姚一带山区的云象奇观和丰富的铜、碧矿藏资源是该传说生成的基础,在西汉"崇祥重祀"的社会背景下,望气之术则成为贯通二者的思想纽带,并将之解释为一种"金碧其质、鸡马其形",代表金玉之气的祥瑞吉兆。 相似文献

ABSTRACTThe US Middle Atlantic region, known for its rich archaeological record and diverse topographic settings, is experiencing a range of climate change impacts, most notably: sea level rise and coastal erosion in its tidal zones. Documented palaeostratigraphic and palynological studies throughout the region provide a record of late Pleistocene/Holocene environmental response to changing climate, confirming observations from other disciplines that the magnitude of modern impacts exceeds past temporal and spatial patterns. The corresponding impact on archaeological resources is great, requiring a renewed effort to document threatened sites while also working with local and state governments to develop mitigation strategies. The Middle Atlantic Archaeological Conference (MAAC) created the Sea Level Rise and Storm Surge Committee to promote regional partnerships in site impact assessment and mitigation strategies. The network highlights the predicament of archaeology in this time of climate change: accelerated research and discovery in the face of catastrophic loss. 相似文献
