Investigation of the Geological, Mineralogical, and Geochemical Contents of the Sedimentary Fills in the Northern Area of the Quaternary-Aged Bor Basin (Niğde/Turkey): Implications for Sediment Source and Paleoclimates

Quaternary
In the northern part of the Niğde (Central Anatolian) Quaternary Bor Basin, stratigraphic sections P1 and P2 were sampled, reaching depths of 11 m and 25 m.

Vegetation and environmental dynamics in the Páramo of Jimbura region in the southeastern Ecuadorian Andes during the late Quaternary.

, 2012
The last 15,000 years of vegetation, fire and climate history were reconstructed from the Laguna Natosa Peat bog core (3600 m elevation) in the Páramo of Jimbura region in the Cordillera Real, close to the Peruvian border of southern Ecuador in the ...

Stratigraphic evidence for modern‐like glacier extents in south‐central Alaska within the last glacial period (MIS 3)

Boreas
The last (Wisconsinan) glacial period was punctuated in North America by two glacial maxima, known as the Early and Late Wisconsinan glaciations. In Alaska, these maxima and their subsequent retreats have been the object of dating efforts to reconstruct ...

Climate change in lowland Central America during the late deglacial and early Holocene [PDF]

The transition from arid glacial to moist early Holocene conditions represented a profound change in northern lowland Neotropical climate. Here we report a detailed record of changes in moisture availability during the latter part of this transition (11 ...

Late-Glacial to Late-holocene Shifts in Global Precipitation Delta(sup 18)O [PDF]

, 2015
Reconstructions of Quaternary climate are often based on the isotopic content of paleo-precipitation preserved in proxy records. While many paleo-precipitation isotope records are available, few studies have synthesized these dispersed records to explore

Late glacial environmental history in Lithuania

, 2006
A detailed description of the Late Glacial environment was attempted through an interpretation of pollen data and lithologi-cal records in the sequences with 14C chronologies. Pollen data suggests that during the pre-Allerod time (>11.9I4C kyr. BP) tree-less vegetation flourished in the area where sedimentation in freshwater bodies with a high water ...

Ice sheet extent and early deglacial history of the southwestern sector of the Greenland ice sheet [PDF]

, 2009
The offshore and coastal geomorphology of southwest Greenland records evidence for the advance and decay of the Greenland Ice Sheet during the Last Glacial Maximum.

Glacial-interglacial atmospheric CO2 change: a possible "standing volume" effect on deep-ocean carbon sequestration [PDF]

So far, the exploration of possible mechanisms for glacial atmospheric CO2 drawdown and marine carbon sequestration has tended to focus on dynamic or kinetic processes (i.e. variable mixing-, equilibration- or export rates).
