Intermontane basins in the Trans-Pecos region of westernmost Texas and northern Chihuahua, Mexico, are target areas for disposal of interstate municipal sludge and have been identified as possible disposal sites for low-level radioactive waste. Understanding ground water movement within and between these basins is needed to assess potential contaminant fate and movement. Four associated basin a...

Introduction: The dynamics of the crust-mantle interface (Moho) underlying lunar impact basins has received considerable study, particularly those with strong positive free-air gravity anomalies associated with the locations of large basins (" mascons ") [e.g. 1-8]. These gravity anomalies, detected via orbital spacecraft observation, indicate that after surface topography and mare loads are ac...

in the nighttime, drainage flow occurs along the basin sideslope and advects cold air to the boundary layer over the basin bottom (bbl), intensifying the cooling rate of the layer. a nocturnal cold air lake develops in the basin, attaining a depth nearly equal to the topographical depth of the basin. heat budget analysis of the whole basin surface shows that net radiative flux closely balances ...

The Amazon Basin is the largest hydrographic basin on the planet, and the dynamics of its aquatic microorganisms strongly impact global biogeochemical cycles. However, it remains poorly studied. This metagenome project was performed to obtain a snapshot of prokaryotic microbiota from four important lakes in the Amazon Basin.

The evolution of the western Mediterranean of an 'interna1 zone plate' by the mechanism basin is considered. The Provence basin invoked by Karig. Lower or middle Miocene results from the Oligocene migration of Conica squeezing of the interna1 zones against the and Sardinia southeastwards. The North North Afncan platform caused ejection of the African basin was created by the dislocation flysch ...

The first otlicial occurrence of the exotic species Clarias gariepinus (Burchell , 1822) in the Rio Paraopeba (Sao Francisco river basin), the Rio Grande (Parana river basin), and the Rio Doce (Doce river basin), is reported, with comments on the possible ecological consequences and on the conservation of freshwater fish biodiversity due to non-native species introductions.

The Tennessee River Basin is considered one of the most important regions for freshwater biodiversity anywhere on the globe. The Tennessee River Basin currently includes populations of at least half of the described contemporary diversity of extant North American freshwater fishes, crayfish, mussel, and gastropod species. However, comparatively little is known about the biodiversity of this bas...

The Nam Pat Group of the Nam Pat Basin, Uttaradit Province, Thailand is situated in the Nan Suture Zone. Two contrasting tectonic framework models of the Nan Suture have previously been proposed: as a main Paleo-Tethyan suture and as a remnant of a closed back-arc basin. The goal of this study is to analyze the tectonic framework of the Nan Suture and reevaluate the existing tectonic models. Th...
