The study area, located in the southern section of the Central Iranian volcano–sedimentary complex, contains a large number of mineral deposits and occurrences which is currently facing a shortage of resources. Therefore, the prospecting potential areas in the deeper and peripheral spaces has become a high priority in this region. Different direct and indirect methods try to predict promising a...

Abstract The aim of this work is to develop a hybrid computational method that combines the grid-characteristic on regular structured grids with discontinuous Galerkin unstructured tetrahedral grids. proposed makes it possible describe integration domains complex-shaped boundaries and contact calculate seismic fields taking into account topography Earth’s surface, while saving resources. This m...

The general focus of this work is to explore, better understand, model and predict the interactive dynamics and variability of sub-mesoscale and mesoscale features and processes in the Philippine Straits region and their impacts on local ecosystems through i. physical-biogeochemical-acoustical data assimilation of novel multidisciplinary observations, ii. adaptive, multi-scale physical and biog...

This paper by Lawson and coworkers reports very interesting results with regard to low molecular weight DOC (LMW-DOC) speciation and abundance in basal ice from glaciers that have different organic and lithological substrates and thermal regimes. The case is made that these LMW-DOC compounds may support and/or be a product of biogeochemical activity beneath glaciers with consequence to regional...

Contributions in biogeochemical research have immensely benefited humankind, including enhanced food production and the quality of our environment. This overview paper focuses on recent breakthroughs in elucidating biogeochemical processes in soils and other natural materials and delineates frontiers for the present decade and beyond. Frontiers will undoubtedly involve multiple spatial and temp...

Deltas – landforms created where sediment is deposited at the mouth of a river – bury vast amounts of organic carbon, thereby playing a central role in the biogeochemical carbon and sulphur cycles (Fig. 1). Delta sediments are highly heterogeneous, varying over space and time, with important consequences for the interaction of sediments with biogeochemical processes. Understanding this complexi...

The group selection debate of the 1960s made it clear that evolution does not necessarily increase population performance. Individuals can be selected to have traits that diminish a common good and make population persistence difficult. At the extreme, the discrepancy between levels of selection is predicted to make traits evolve towards values at which a population can no longer persist (evolu...

There has been considerable recent interest in the ecosystem consequences of global and regional shifts in biogeochemical cycling and the loss of species diversity. Since biogeochemical cycling is the result of an interaction of numerous organisms, the link between diversity and biogeochemistry is a natural one. changes in either diversity or biogeochemiical &ling can dramatically influence one...
