(PANGAEA, 2000-06-15)A new generalized schematic map of distribution of recent sediments within Eurasian Arctic shelves is considered. The sediments have accumulated as a result of interaction of various factors and processes specific to high ...
-
(PANGAEA, 1995-11-18)Foraminifera were examined in recent (<100 years) fine-grained glaciomarine muds from surface sediments and cores from Nordensheld Bay, Novaja Zemlja, and Hornsund and Bellsund, Spitsbergen. This study presents the first ...

Recognition of Early Eocene global carbon isotope excursions using lipids of marine Thaumarchaeota. (PANGAEA, 2013-10-06)The Paleocene-Eocene Thermal Maximum (PETM; ~56 Ma) and Eocene Thermal Maximum 2 (ETM2; ~53 Ma) are geological short (<200,000 years) episodes of extreme global warming and environmental change. Both the PETM and ETM2 are ...
-
(PANGAEA, 2003-04-11)Oxygen isotope records, radiocarbon AMS data, carbonate and opal stratigraphy, sediment magnetic susceptibility, tephrachronology, and paleontological results were used to obtain detailed sediment stratigraphy and an age ...
-
(PANGAEA, 2015-01-06)Marine- and terrestrial-derived biomarkers (alkenones, brassicasterol, dinosterol, and long-chain n-alkanes), as well as carbonate, biogenic opal, and ice-rafted debris (IRD), were measured in two sediment cores in the Sea ...
-
(PANGAEA, 2016-05-20)Reliable information of past vegetation changes are important to project future changes, especially for areas undergoing rapid transitioning such as the boreal treeline. The application of detailed sedDNA records has the ...
-
(PANGAEA, 2019-08-16)The Black Sea repeatedly experienced major hydrographic changes during glacial-interglacial transitions, with alternating limnic and brackish stages. While the redox conditions during the present Holocene brackish period ...

(PANGAEA, 2016-09-22)The large amounts of soil organic matter (SOM) in permafrost-affected soils are prone to increased microbial decomposition in a warming climate. The environmental parameters regulating the production of carbon dioxide (CO2) ...
-
(PANGAEA, 2008-09-02)During summer periods of 2003-2005, spatial and vertical distributions of suspended particulate matter and bacteria in stratified and homogeneous waters of the White Sea was studied. Results of the study of various ...
-
(PANGAEA, 2015-06-05)Pollen productivity estimates (PPE) are used to quantitatively reconstruct variations in vegetation within a specific distance of the sampled pollen archive. Here, for the first time, PPEs from Siberia are presented. The ...
