Earth's climate is constantly changing, with alternating cycles of glacial advance
Objective: The Earth s surface has been dominated by cycles of glacial advance
for more than two million years.
They repeat a disproven claim that the Toba eruption 74 ka BP caused a glacial advance
It's also a cautionary tale for those who rely almost exclusively on cycles of glacial advance
and retreat to study sea-level changes.
Cross sections show that nearly similar depositional environments existed before each late Wisconsinan glacial advance
Rampton (1982) assigned the "Buckland Glaciation," the single glacial advance
on the Yukon Coastal Plain that formed the ice-thrust ridge of Herschel Island, to the Early Wisconsinan interval (Fig.
As the woody debris in the present study dates from 30,070 [+ or -] 240 y BP, the Newport sample predates the Wedron Formation and, thus, the glacial advance
of the Late Wisconsinan (i.
However, during times of peak glacial advance
, the inhabitable latitudinal span of North America was tightly constricted.
I write to congratulate you on a very informative article on the real reasons behind glacial advance
and retreat (Sounding the retreat, December 2007).
2005, Younger Dryas glacial advance
in the southern Gulf of Lawrence, Canada; analogue for ice inception?
where some tardigrade xenarthrans have survived at least until the last glacial advance
The age of these Jefferson mammoth remains suggests that this species inhabited the Saginaw Bay region of central Michigan in the interstaclial, icefree interval immediately prior to the late Wisconsin glacial advance
