Areas where landslides occurred recently tend to have sharply defined surface features, whereas older sites are often smoother because of erosion. So the researchers used the roughness of the ...

The new model now corresponds much more closely to the evidence left on the ground following the retreat of the glaciers and makes it possible to better quantify many natural phenomena, such as ...

We provide thermochronologic evidence of rock cooling and multiple kilometers of exhumation in the Cryogenian Period in support of a glacial origin for erosion contributing to the composite basement ...

EM1 variation was consistent with that of the clay content; both were higher during glacial periods and lower during interglacial periods. A comprehensive study of bulk OC fluxes and geochemical ...

Otsu’s method was utilized to optimize thresholds of NDSI, and three machine learning algorithms [random forest (RF), support vector machine (SVM), and classification and regression tree (CART)] were ...
