-
(2000)The presence of inhomogeneous sedimentation is acknowledged as being an important problem in palaeolimnological studies. Sediment records can be disturbed by erosional and redepositional events, which redeposit microfossils ...

CLIMATE DURING PERMIAN-TRIASSIC BIOSPHERE REORGANIZATIONS, ARTICLE 1: CLIMATE OF THE EARLY PERMIAN (2002)The Permian was marked by transition from the glacioera to the thermoera, the last one in the geo- logical history. This global climatic reorganization followed the significant paleogeographic changes related to Pangea ...
-
(2003)The Late Permian-initial Triassic was a period of the Earth climate change, as the glacial climate of the Late Paleozoic was replaced by the non-glacial one of the Mesozoic. The intricate trend of this process is reconstructed ...
-
(2003)We have revisited the climate friction scenario during the Earth's major glacial episodes of the last 800 Myr: the Late Pliocene-Pleistocene $(~0-3 Ma)$, the Permo-Carboniferous $(~260-340 Ma)$ and the Neoproterozoic $(~750 ...
-
(1999)Using a climatic calibration based on the scores of the plant functional types (PFTs) calculated for 1245 surface pollen spectra, the climate at 6 ka BP has been reconstructed for a set of 116 pollen spectra from the former ...
-
(2001)In this paper we discuss some theoretical results obtained for climate models (theorems for the existence of global attractors and inertial manifolds, estimates of attractor dimension and Lyapunov exponents, symmetry ...

-
(2000)Temperature changes at the Earth's surface propagate downward into the subsurface and impart a thermal signature to the rocks. This signature can be measured in boreholes and then analyzed to reconstruct the surface ...
-
(2005)Life at the Permian-Triassic boundary (ca. 251 Ma) underwent the largest disruption in Earth's history. Paleoclimatic data indicate that Earth was significantly warmer than present and that much of the ocean was anoxic or ...
-
(1996)The similar temporal behaviour of climate parameters and the Earth's rotation leads to the assumption that there exists a relation between both phenomena. As is well known, the relationship between atmospheric dynamics and ...
-
(2004)Existing methods for determining paleoelevation are primarily limited by (1) large errors (±450 m), (2) a reliance on incorrect assumptions that lapse rates in terrestrial temperature decrease with altitude in a globally ...
-
(1997)The climate of the Holocene is not well suited to be the baseline for the climate of the planet. It is an interglacial, a state typical of only 10% of the past few million years. It is a time of relative sea-level stability ...
-
(1999)A palynological analysis of the Baikal sediments from a 200 m deep borehole permitted tracing continuous climatic and vegetation changes in the Baikal region for the last 5 Ma (from the Early Pliocene). The sediment age ...

(PANGAEA, 2005-12-22)A Marine Isotope Stage (MIS) 3/early MIS 2 section from a structural high along the east coast of the North Basin of Lake Baikal was analysed for diatoms, C/N ratios, and organic carbon isotope ratios. Diatoms were present ...

-
(1988)As far as the climatic history of the Late Cenozoic is concerned, the second half of the Pliocene is especially interesting because during that comparatively short time interval there were many important paleogeographic ...
-
(PANGAEA, 2001-10-29)Plant macrofossil investigations were carried out on Late-Quaternary deposits at Cape Sabler (NW shore of Lake Taymyr, Siberia). Four dated samples (three Late Pleistocene, one Holocene) rich in plant macrofossils were ...
