A buried paleovalley system, up to 2 km wide and exceeding 50 m in relief, made up of multiple cross-cutting depressions incised into the Lower Pleistocene bedrock, is reported from the central Adriatic coastal plain at the mouth of Biferno River.
The rate of physical weathering or lowering of the bedrock surface is represented as an exponential decline with soil thickness.
But the Federal Reserve Bank of New York holds the prize as the world's biggest known stockpile of gold, some 550,000 glistening bars of the stuff buried deep into the bedrock of lower Manhattan.
The methodology presented here will facilitate new discoveries in the fluvial environment that have historically been difficult due to access and imagery resolution issues, and provide greater perspective on channel signatures and responses to a host of landscape forcings, especially in tectonically active bedrock and lower order drainage systems.
"The actual bedrock is much lower," Cowan told me.
The Spence School has turned a landmark mansion at 56 East 93rd Street into its new lower school, burrowing deep into bedrock -- as noise-bedeviled neighbors can attest -- to create a subterranean gymnasium.
The bedrock is mainly Lower Cambrian sandstone and phyllite.
Therefore, it is expected that these areas have higher concentrations of phosphorous than lower areas dominated by schistose bedrocks, where soils are often thicker, older and more rich in organic matter.
The latter result, however, is not valid for profile sets NP and TP, because of the uniformity of bedrock velocity, which lowers the relative importance of C v compared to V S30.
Hence, scatter in plots of soil production as a function of soil depth are to be expected in many landscapes, and if the landscape is in geomorphic steady state, this scatter reflects the stochastic nature of the block release mechanism by which the bedrock interface is lowering.
