14 wrz 2018 · Overall, the Mississippi deep-sea fan deposits reveal that glacial-interglacial transitions in North America did modify major river systems over the last 70 ka, that the modern...
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.
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.
15 lut 2022 · These spatiotemporally constrained paleo-glaciers can then, in turn, be used to infer paleoclimate conditions in the northern Rocky Mountains during the last glaciation for which relatively few records exist compared to other regions of western North America.
23 lut 2021 · At present, there are no direct indicators of the size of the ice sheets during the peak MIS 4 glaciation except in northern Europe and in the North American Cordillera (see Supplementary...
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 · We here assess the vegetation dynamics in northwestern North America during the late Pliocene and early Pleistocene (c. 2.8–2.4 Ma) based on a pollen record from a lacustrine sequence from paleo-Lake Idaho, western Snake River Plain (USA) that has been retrieved within the framework of an International Continental Drilling Program (ICDP ...
