Sedimentary geolipid records of historical changes in the watersheds and productivities of Lakes Ontario and Erie
The organic matter contents of sediments deposited in Lakes Erie and Ontario contribute to the record of changes in the lake watersheds and aquatic ecosystems which have resulted from European settlement and cultural eutrophication of these systems over the past two centuries. Compositions of n-alkanes and n-alkanoic acids extracted from lake sediments track the clearing of the original natural...
متن کاملApplication of SAR DATA to the Study on the Characteristics of Sedimentary Environments in a Tidal Flat
In this study, comparisons of the backscattering coefficients and the coherence values which had been extracted from SAR (Synthetic Aperture Radar) images such as JERS-1, ENVISAT and ALOS satellites with surface roughness, surface geometric and soil moisture content were carried out. As the results of analysis using the backscattering coefficient and coherence values from SAR images, the cohere...
متن کاملDecay factors and patterns of stones in open-air historical sites built of carbonate sedimentary stones
The number of historical open-air sites built of stone are relatively limited in comparison to the other historical artificial in Iran, but these sites include great significance in terms of value, historic and their knowledge of past. Since these stone poen-air sites are generally about two thousand years old, they have been exposed to decay factors for a long time. Many information and data o...
متن کاملSedimentary polycyclic aromatic hydrocarbons: the historical record.
Polycyclic aromatic hydrocarbons in three sections of a dated sediment core from Buzzards Bay, Massachusetts, have been analyzed by gas chromatographic spectrometry. This historical information suggests that sedimentary polycyclic aromatic hydrocarbons, at least at this location, result primarily from the anthropogenic combustion of fossil fuels.
متن کاملPond fractals in a tidal flat.
Studies over the past decade have reported power-law distributions for the areas of terrestrial lakes and Arctic melt ponds, as well as fractal relationships between their areas and coastlines. Here we report similar fractal structure of ponds in a tidal flat, thereby extending the spatial and temporal scales on which such phenomena have been observed in geophysical systems. Images taken during...
