East Siberian Sea
The East Siberian Sea ( rus, Восто́чно-Сиби́рское мо́ре, r=Vostochno-Sibirskoye more) is a marginal sea in the Arctic Ocean. It is located between the Arctic Cape to the north, the coast of Siberia to the south, the New Siberian Islands to the west and Cape Billings, close to Chukotka, and Wrangel Island to the east. This sea borders on the Laptev Sea to the west and the Chukchi Sea to the east. This sea is one of the least studied in the Arctic area. It is characterized by severe climate, low water salinity, and a scarcity of flora, fauna and human population, as well as shallow depths (mostly less than 50 m), slow sea currents, low tides (below 25 cm), frequent fogs, especially in summer, and an abundance of ice fields which fully melt only in August–September. The sea shores were inhabited for thousands of years by indigenous tribes of Yukaghirs, Chukchi and then Evens and Evenks, which were engaged in fishing, hunting and reindeer husbandry. ...

Lava Flow
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is also often called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. The word ''lava'' comes from Italian and is probably derived from the Latin word ''labes'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Russian Hydrographic Service
The Russian Hydrographic Service, full current official name Department of Navigation and Oceanography of the Ministry of Defence of the Russian Federation ( rus, Управление навигации и океанографии Министерства обороны Российской Федерации), is Russia's hydrographic office, with responsibility to facilitate navigation, performing hydrographic surveys and publishing nautical charts. Since the Russian state is of such a vast size and nature that it includes many different seas, long and indented coastlines and a great number of islands, as well as a complex system of waterways and lakes, surveying has been an indispensable activity for the Russian Navy since its modernization at the time of Czar Peter the Great in the 17th century. The hydrographic service has been historically attached to the Russian Navy and the agents and supervisors of hydrographic works have been largely naval officers throughout its history ...

Arctic Ocean Hydrographic Expedition
The Arctic Ocean Hydrographic Expedition (GESLO) (1910–1915) was a scientific expedition organized by Russia for the purpose of the development of the Northern Sea Route. This expedition accomplished its goal of exploring the uncharted areas of the continental side of the Northern Sea Route in what was seen as the culmination of the Great Northern Expedition, an ambitious enterprise initially conceived by emperor Peter I the Great to map the whole of the northern coast of Russia to the east. Expedition Two icebreaking steamers Vaigach and Taimyr were used for the venture. The plan of the expedition was developed with the active participation of A.V. Kolchak and F. A. Matisen. The 32 man expedition was headed by Boris A. Vilkitsky and was staffed with military seamen and hydrographers, such as Konstantin Neupokoev. The biological and geological collections were performed by military doctors L. M. Starokadomsky on icebreaker "Taimyr" and E. E. Arnold on icebreaker "Vay ...

Icebreaker Vaygach
Icebreaker ''Vaygach'' (russian: Вайгач) was an icebreaking steamer of moderate size built for the Russian Imperial Navy at St. Petersburg in 1909. She was named after Vaygach Island in the Russian Arctic. ''Vaygach'' and her sister ship ''Taymyr'' were built for the purpose of thoroughly exploring the uncharted areas of the Northern Sea Route. This venture became known as the Arctic Ocean Hydrographic Expedition. The first of a series of surveys began in the autumn of 1910, when ''Vaygach'' and ''Taymyr'' left Vladivostok. They entered the Chukchi Sea with scientists on board and began their exploration. For the next five years, these icebreakers went on sounding and carrying on vital surveys during the thaw. Before every winter, when ice conditions became too bad, they returned to Vladivostok and waited for the spring. In 1911 the scientists and crew aboard ''Vaygach'' and ''Taymyr'' made the first Russian landing on Wrangel Island. In 1914, led by Colonel I. Sergeev, ...

Megaannum
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year (the mean yea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lherzolite
Lherzolite is a type of ultramafic igneous rock. It is a coarse-grained rock consisting of 40 to 90% olivine along with significant orthopyroxene and lesser amounts of calcic chromium-rich clinopyroxene. Minor minerals include chromium and aluminium spinels and garnets. Plagioclase can occur in lherzolites and other peridotites that crystallize at relatively shallow depths (20 – 30 km). At greater depth plagioclase is unstable and is replaced by spinel. At approximately 90 km depth, pyrope garnet becomes the stable aluminous phase. Garnet lherzolite is a major constituent of the Earth's upper mantle (extending to ~300 km depth). Lherzolite is known from the lower ultramafic part of ophiolite complexes (although harzburgite is more common in this setting), from alpine-type peridotite massifs, from fracture zones adjacent to mid-oceanic ridges, and as xenoliths in kimberlite pipes and alkali basalts. Partial melting of spinel lherzolite is one of the primary sou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xenolith
A xenolith ("foreign rock") is a rock fragment (country rock) that becomes enveloped in a larger rock during the latter's development and solidification. In geology, the term ''xenolith'' is almost exclusively used to describe inclusions in igneous rock entrained during magma ascent, emplacement and eruption. Xenoliths may be engulfed along the margins of a magma chamber, torn loose from the walls of an erupting lava conduit or explosive diatreme or picked up along the base of a flowing body of lava on the Earth's surface. A xenocryst is an individual foreign crystal included within an igneous body. Examples of xenocrysts are quartz crystals in a silica-deficient lava and diamonds within kimberlite diatremes. Xenoliths can be non-uniform within individual locations, even in areas which are spatially limited, e.g. rhyolite-dominated lava of Niijima volcano (Japan) contains two types of gabbroic xenoliths which are of different origin - they were formed in different temperature and ...
