-
(PANGAEA, 2013-08-16)Mineral composition of recent bottom sediments was studied in the White Sea. A single terrigenous-mineralogical province is defined; it is characterized by a mineral association of amphibole, epidote, garnet, and pyroxene. ...

(PANGAEA, 1983-12-07)The study of lake deposits containing iron-manganese nodules is of significant interest for the understanding of one of the continental manganese and iron concentration processes. In the USSR, much attention has been given ...
-
(PANGAEA, 2018-12-20)We developed a spatial model that combines fine-scale livestock numbers with their associated energy requirements to distribute livestock grazing demand onto a map of energy supply, with the aim of estimating where and to ...
-
(PANGAEA, 2017-09-11)Most northern peatlands developed during the Holocene, sequestering large amounts of carbon in terrestrial ecosystems. However, recent syntheses have highlighted the gaps in our understanding of peatland carbon accumulation. ...
-
(PANGAEA, 2005-07-17)River discharge of Ob and Yenisei to the Kara Sea is highly variable on seasonal and interannual time scales. River water dominates the shallow bottom water near the river mouths, making it warmer and less saline but ...
-
(PANGAEA, 2002-10-14)Studies of the annual pollen and spore deposition in different areas of the Lena Delta were undertaken for the first time in the Asian sector of the Arctic during the Russian-German ''LENA 98'' and ''LENA 99'' expeditions ...

(PANGAEA, 1997-09-25)Sediment samples from the Laptev Sea, taken during the 1993 RV Polarstern expedition ARK IX/4 and the RV Ivan Kireyev expedition TRANSDRIFT I, were investigated for the amount and composition of their organic carbon ...
-
(PANGAEA, 2012-02-13)For the reconstruction of sea-ice variability, a biomarker approach which is based on (1) the determination of sea-ice diatom-specific highly-branched isoprenoid (IP25) and (2) the coupling of phytoplankton biomarkers and ...

(PANGAEA, 2011-05-25)The investigation of the Baikal Lake bottom carried out during summer 2008 by means of the Mir deep-sea manned submersibles resulted in sampling of a series of sediments, ferruginous crusts, and peculiar mineralized tubes ...
-
(PANGAEA, 2010-07-15)Detailed knowledge of the extent of post-genetic modifications affecting shallow submarine hydrocarbons fueled from the deep subsurface is fundamental for evaluating source and reservoir properties. We investigated gases ...
-
(PANGAEA, 2016-03-16)The goal of this study was to examine the potential of a unique X-band SAR dataset to monitor ice phenology and bedfast ice on a number of thermokarst lakes in the Siberian Arctic. Three-year repeat-pass TSX time series ...
-
(PANGAEA, 2002-03-06)According to monitoring data gained between 1982-1992, macrobenthos in the Tiksi Bay is characterized by low indices of the total abundance, biomass and taxonomic diversity. 30 macrobenthic species have been recorded in ...
