(PANGAEA, 2014-11-05)The last glacial-interglacial transition or Termination I (T I) is well documented in the Black Sea, whereas little is known about climate and environmental dynamics during the penultimate Termination (T II). Here we present ...
-
(PANGAEA, 2012-05-31)Sediments from the Black Sea, a region historically dominated by forests and steppe landscapes, are a valuable source of detailed information on the changes in regional terrestrial and aquatic environments at decadal to ...
-
(PANGAEA, 2015-02-10)Siberian arctic vegetation and lake water communities, known for their temperature dependence, are expected to be particularly impacted by recent climate change and high warming rates. However, decadal information on the ...

(2002)An abrupt change in the coal-producing plants is established near the boundary between the Tal'bei and Seida formations and their analogs in the Pechora coal basin and the Cis-Urals. Predominant among plant remains of coal ...
-
(PANGAEA, 2019-01-04)Synthetic aperture radar (SAR) applications often require normalization to a common incidence angle. Angular signatures of radar backscatter depend on surface roughness and vegetation cover, and thus differ, from location ...
-
(1998)The results of palynological analysis of a section of unconsolidated deposits in the 12-m-high coastal escarpment of the Baidaratskaya Bay (68°51′N, 66°54′E), the southeastern part of the Yugorskii Peninsula, are outlined. ...

(PANGAEA, 2016-07-18)Palaeoecological investigations in the larch forest-tundra ecotone in northern Siberia have the potential to reveal Holocene environmental variations, which likely have consequences for global climate change because of the ...
-
(1999)The phytomass (the biomass of terrestrial vegetation) is one of the main reservoirs of carbon, as carbon makes up approximately 0.45 of the phytomass by weight [Ajtay, G.L., Ketner, P., Duvigneaud, P., 1979. Terrestrial ...

(1988)In the middle of the 1970's in the Khaydarkan antimony-mercury deposit, Kirgizia, one of the present writers (Volgin) found a new copper-mercury-tin sulfide. It was called velikite after A.S. Velikiy. The composition of ...
-
(2004)The speed of propagation of compressional-wave energy in the subsurface, known simply as "formation velocity," is strongly influenced by compaction, particularly in young clastic basins. Because pore pressures affect ...
-
(1987)The asthenosphere of the Sea of Okhotsk is structurally very complex. The depth of its top edge, its thickness and its dip range, respectively, from 40 to over 250 km, from 35 to 160 km and from zero to 30°. We should ...
