However, the analysis the underlying bedrock on which the marine ice sheet of Wilkes Basin stands suggests this is not the case.
Obviously, the amplitudes observed are determined by local attributes of the underlying bedrock so that locations associated with granitic terrain generate the largest medians and highest value tails.
Geologically, a predominant feature of the substrata of Manhattan is that the underlying bedrock base of the island rises considerably closer to the surface near Midtown Manhattan, dips down lower between 29th Street and Canal Street, then rises toward the surface again in Lower Manhattan.
Major factors affecting the initiation of slope failure and subsequent modes of movement appear to be dependent upon the morphology, the nature and degree of weathering of the underlying bedrock, and the moisture status of the loess deposits.
In addition to the chemical concentration of underlying bedrock and soil, the factors affecting element concentrations in peat were the topography of the environment including paludification mode and species composition and the subsiding relations of the peatland and drainage.
However, to obtain first-order estimates of (F_{a}) and (F_{v}) values for the linear response of a given site, the first step is to approximately identify the stiffness of underlying bedrock.
Because the age of underlying bedrock is one factor hypothesized to influence 87Sr/86Sr ratios [36], we predicted a positive relationship between 87Sr/86Sr in feathers (87Sr/86SrF) and bedrock age.
Our study also provides the first test of the hypothesis that 87Sr/86Sr ratios in birds are related to the age of underlying bedrock across large geologic scales.
