[1] Particulate organic carbon (POC) export fluxes were estimated in the shelf-slope region of the Chukchi Sea using measurements of Th U disequilibria and the POC/Th ratio in large (>53-mm) particles. These export fluxes were used in conjunction with rates of primary productivity and benthic carbon respiration to construct a POC budget for this shelf-slope region. Samples were collected along ...

Sediment samples were collected to delineate the distribution of contaminants along the central California coast. Sampling included a variety of Canyons and shelf/slope areas to evaluate contaminant transport patterns and potential delivery to Canyons and the continental slope to a depth of 1200 m. Sediments were collected and analyzed for organic contaminants using standard techniques of the N...

The present study focuses on facies analysis and the reservoir characteristics of the Asmari Formation in the Aghajari oilfield (located in the Zagros fold-thrust belt, southwest Iran), and how they are linked to depositional environments and reservoir characteristics. This formation consists of about 380 m carbonates with some siliciclastic intercalations. Based on the integration of 1200 m of...

managers always consider the precise estimation of sediments in watersheds due to various conditions, such assoil and water resources management, construction, infrastructure and economical and social issues. in this condition,an optimized determination of sediment rating equation (typical method until now for sediment yield estimation) isessential to investigate sediment yield in rivers. in th...

The Pacific Rim Complex is exposed in a fault-bounded slice along the west coast of Vancouver Island. It is divided into two parts: (I) the Ucluth Formation, a basement unit composed of lower Mesozoic arc-volcanic rocks, and (2) a suprajacent sedimentary se­ quence, more than 2 km thick, composed of Lower Cretaceous olistostromal melanges. An unconformity is present, at least locally, at the Uc...

stars valley is one of the tourism areas in the qeshm island and is located at the southwest of qeshm city, south eastern corner of the island. sediments forming this unique landscape are not completely lithified and is composed of marl and marly limestone which is formed by erosional and weathering processes. deposits of stars valley contain diverse assemblages of echinoids, bivalves, gastropo...

small precipitation with temporal and spatial variation of rainfall is the main responsible factors on flood occurrence in arid and semi arid regions. floods in their regions usually contain high concentration of sediments which when they are deposited on the surface of lands, they change the properties of soils of the area. in this research, the effect of floodwater spreading on physic-chemica...
