Добрый день, Коллеги. Важное сообщение, просьба принять участие. Музей Ферсмана ищет помощь для реставрационных работ в помещении. Подробности по ссылке
This planet contains so much water that perhaps it should have been better named Oceania. It is the only known body in the solar system that is surrounded by water filled with unique geologic structures and teeming with a staggering assortment of marine life. Some of the strangest creatures on Earth, whose ancestors go back several hundred million years, live on the deep ocean floor.
During the past century, scientists, world statesmen, and international entrepreneurs have become increasingly aware of the potential of the oceans as a source for minerals. This book provides an authoritative picture of the currentstate of marine mineral extraction. A major work of reference, it will be essential reading both for those engaged in maritime studies and for professional organizations involved in the extraction of underwater minerals.
The fragile Antarctic environment consists of a closely linked system of the lithosphere, atmosphere, cryosphere, hydrosphere and biosphere. Changes in this system have influenced global climate, oceanography and sea level for most of Cenozoic time. The geological history of this region therefore provides a special record of important interactions between the various components of the Earth System.
Быть - может, многим из читателей случалось видеть море, то спокойное и блещущее торжественной красой, то бурное, мрачное и угрожающее, и иногда .задуматься о том, что скрывает под собою эта необъятная масса вод. Зто выражение — необъятная, вовсе не преувеличено.
The late Dr. T. Wayland Vaughan, who had long been interested in marine ecology and paleoecology, in 1940 planned and organized a Subcommittee on the Ecology of Marine Organisms as a part of the Committee on Geologic Research (Norman L. Bowen, Chairman) in the Division of Geology and Geography of the National Research Council of the National Academy of Sciences. The members of this Subcommittee were:
Представлены и проанализированы методы дистанционного зондирования, разработанные в западных государственных и частных компаниях, а также советскими специалистами во второй половине прошлого века, для поисков нефти и газа в пределах морей и океанов, в том числе совершенно неизученных территорий.
Подготовка инструкции по составлению проектов и смет на морские геологоразведочные работы осуществлена Экономическим управлением и управлением ресурсов недр шельфа и Мирового океана Роском недра с участием Всероссийского научно-исследовательского института экономики минерального сырья и недропользования (ВИЭМС). ТАО «Океаногеоресурсы», института «Экономика» и организаций Северо-Западного регионального геологического центра.
Basic data on the opening of backarc basin, South China Sea (abbreviated as SCS hereafter) basin, were obtained through a two-year Japan and China cooperative joint marine geophysical survey in 1993 and 1994. Some new gravity, magnetic and seismic structural data by reflection as well as refraction study of SCS were obtained and added to existing data. A systematic three component magnetic measurement was made for the first time in this basin. These data in addition to those of earlier studies are constraints for depicting a thinning of a continental crust and later followed by a backarc basin opening by ocean floor spreading. Gravimetric and magnetic anomalies, heat flow, and ages of drilled rocks from this area are referred to speculating on the opening scheme of SCS. Origin of disoriented and scattered magnetic anomaly lineations is suggested to be due to intermittent activities along opening ridge systems of SCS. <...>
Geologists have always known the importance of investigating the world's vast submerged territory, but until the 1940s it remained virtually a terra incognito. Finally, the world's worst war, along with all its horror, had among a few redeeming features the persuasion of naval scientists and their civilian advisors that naval operations needed a background knowledge of the ocean and its floor.
