14 wrz 2018 · Often occurring over geologically short (<10 4 years) time scales, large-scale paleo-geographic changes related to Pleistocene ice sheets significantly affected the evolution and migration ...
16 sie 2019 · These spatial patterns in Late Pleistocene ice extent suggest that glaciation may be initiated in the Pacific region, before spreading to the North Atlantic region.
The Quaternary glaciation, also known as the Pleistocene glaciation, is an alternating series of glacial and interglacial periods during the Quaternary period that began 2.58 Ma (million years ago) and is ongoing.
23 lut 2021 · We present a global ice sheet reconstruction for the past 80 000 years, called PaleoMIST 1.0, constructed independently of far-field sea level and δ18 O proxy records. Our reconstruction is ...
15 lut 2022 · Reconstructions of Pleistocene glaciers in the northern Rocky Mountains of western Montana are limited (Pierce, 2003), and relatively little work has been done inferring past climate in the region from paleo-glacier characteristics.
Laurentide Ice Sheet, principal glacial cover of North America during the Pleistocene Epoch (about 2,600,000 to 11,700 years ago). At its maximum extent it spread as far south as latitude 37° N and covered an area of more than 13,000,000 square km (5,000,000 square miles).
7 sty 2021 · Augmented by quantitative pollen-based climate estimates, it provides new insight into the characteristics of climate and terrestrial ecosystem variability in northwestern North America during the intensification of Northern Hemisphere glaciation.
