Probabilistic source-to-sink analysis of the provenance of the California paleoriver: implications for the early Eocene paleogeography of western North America
The Latest Paleocene to Early Eocene Colton and Wasatch Formations exposed in the Roan Cliffs on the southern margin of the Uinta Basin, UT make up a genetically related lobate wedge of dominantly fluvial deposits. Estimates of the size of the river that deposited this wedge of sediment vary by …

Joint routing protocol and image compression algorithm for prolonging node lifetime in wireless sensor network
… of node lifetime and network connectivity due to limited power resource of the node. The conventional data routing protocols do not consider the power available at the node on the path from source to sink, thus they result in the exhaustion and eventual death of nodes surrounding the sink node, …

Signatures of land-ocean interactions in coastal morphology
Studying coastal and island evolution in response to environmental drivers offers numerous scientific and societal benefits, as coasts are among the most densely populated regions on Earth. Quantifying surface processes is essential for understanding large-scale landscape development and …

Interrelationships between Soybean Seed Quality Characteristics
… acids supplied in the lowest quantity relative to the animal’s requirement limit growth. Examination of soybean protein across genetic sources and environments has indicated that the abundance of potentially limiting amino acids within soybean protein may be influenced by the seed protein …

Holocene Palynology of the Gulf of Papua, Papua New Guinea: Using Modern Palynomorph Distribution to Better Constrain Paleoenvironmental Changes
… NSF (National Science Foundation)-funded MARGINS Source-to-Sink cruises were conducted in the Gulf of Papua (GoP), Papua New Guinea (PNG), from 2003 through 2005 to better understand how sediment is created, transported, and deposited. Although much work has been done on the data collected during …

Deep-marine depositional systems of the western North Atlantic: Insights into climate and passive-margin evolution
… sedimentary rocks represent an important repository for signals pertaining to the history and evolution of Earth. Whereas the specific processes reflected by the stratigraphic record differ with respect to a given depositional environment, deposits in deep-marine settings, particularly passive …

Sedimentology of the lower Uitenhage Group in the Middle to Late Mesozoic Oudtshoorn Basin, South Africa
… the sedimentary basins that have been linked to the break-up of southern Gondwana. Filled by the continental lower Uitenhage Group, which for the most part is sparsely fossiliferous, difficult to correlate on a regional scale and void of non-renewable natural resources, the Oudtshoorn Basin is …

Isotopic characterization of bedrock, sediments, and minerals as provenance tools: Examples from an inselberg in the Mojave Desert of SE California
… of the processes which shape the landscape. The source, formation, and transport pathways of sediment are critical components to understanding crustal processes and changes and are often grouped under the broad scope of provenance analysis. Much of what we know of how sediments evolve and shape …

Multi-scale deep-marine stratigraphic expressions in the Cretaceous Magallanes Basin, Chile: Implications for depositional architecture and basin evolution
… on Earth and one of the final segments in source-to-sink routing systems. As such, they serve as conduits as well as intermediate or final storage for large volumes of sediment, paleoenvironmental signals, and pollutants on their way to the deep ocean. Over the years, these systems have …

Stable Carbon and Nitrogen Isotopes of Shell Bound organic Matter, Implications for Modern and Ancient Food Web Dynamics
<p>Stable isotopes are an important tool for solving biogeochemical problems and have been increasingly applied in ecosystem studies because of their utility as source-to-sink tracers and for ecological information. Elements like C and N have more than one stable isotope, and their isotopic …

Heterogeneous Strain Distribution & the Effects of High Frequency Climate Change on the Evolution of Early-Stage Rift Systems: Case Studies from Lakes Tanganyika and Malawi (Nyasa), East Africa
… rift basins is a fundamental aspect of plate-tectonics and the first step that ultimately leads to plate-spreading, new continent formation, and the creation of ocean basins. Within continental rifts, processes associated with extensional faulting drive uplift and subsidence of the landscapes …
