A brief increase in wind intensity between 11,100 and 10,700 yr B.P. is recorded by a sharp increase in sediment grain size at eolian sections along the Nenana River in central Alaska. This occurred at the same time as the Younger Dryas climatic
reversal in northern Europe and an increase in the vigor of atmospheric circulation recorded by Greenland ice cores. Climatic fluctuations in high latitude areas during Younger Dryas time may reflect variations in the CO2 content of the atmosphere.

The results presented here confirm the use of the ultrasonic apparatus as a technique for indirectly determining rock strength by determining Dynamic Young's Modulus. The results also indicate that the ultrasonic apparatus can be used as a field

Temporal variations in soil erodibility

the pedostratigraphical record was preserved, the Bt formation can be mainly attributed to the Bolling Inteerstadial. Younger events exist also in the Early Holocene. In most of these sites, Holocene pedogenesis is reduced to an acidification of even a podzolization

and McLean must also be considered younger than previously thought. The persistence of the Laurentide Ice Sheet margin on the central Labrador coast until 7 600 yr ago probably restricted the northward movement of early prehistoric people into northern

The AA. examine paleoclimatic evidence from northeast Asia. The primary data are pollen time-series from three high sedimentation-rate marine cores from which a cooling event described as coeval with the Younger Dryas Chronozone has been identified

This study examines the dichotomy that C 14 ages for noncollagenous fossils are underestimated, whereas ages for collagenous fossil bones are more accurate. There is a high probability that amino acids from poorly preserved fossils will date younger
