The capacity of lake sediments to retain phosphorus can provide an important buffer to eutrophication. Concentrations of total phosphorus (TP) in the surface sediment of a shallow calcareous lake (Lough Carra, Ireland) varied significantly across three basins and were correlated strongly with iron and manganese, but correlated inversely with calcium carbonate. The concentrations of phosphorus i...

The climate of the Great Lakes Region is determined by the general westerly atmospheric circulation, the latitude, and the local modifying influence of the lakes. Due to the lake effect, the regional climate alternates between continental and semi-marine. The semi-marine climate is more consistent contiguous to the lakes, but with favorable meterological conditions, it may penetrate deeply inla...

The dynamics of negatively buoyant river plumes in a small multi-basin kettle lake with steep bathymetry (Toolik Lake, AK) are simulated using a Cartesian hydrodynamic model based on the solution of the three-dimensional shallow water equations. To validate the model, model predictions are compared with results from previous analytical and laboratory studies and with field observations. The gri...

Abstract The Urmia Lake National Park (NW Iran) represents a unique ecosystem owing to special ecological conditions prevailing the region. The Urmia Lake National Park comprises a range of normal to extreme environments, with variable range of salinity between 120-300 g/L. The present study was aimed to characterize ascomycetous yeast mycobiota inhabiting hypersaline soils in this region. Soi...

urmia lake is the largest lake in the country which during recent years faces a dramatic reduction in the water level. many reasons such as climate change, continuous droughts, development of cultivation and land use changes as well as construction of dams were mentioned, but the provided reasons have less been well documented by scientific evidences. this study is an attempt to investigate the...

In 2019, excavations of the Nakhchivan Tepe settlement were found a Neolithic layer which characterized ceramic products with impression ornament. Finding allows reviewing connections between cultures Mill Plain, Karabakh and basin Lake Urmia. On basis research, it can be said that Plain Karabakh, are by ornament, contributed to formation Dalma culture. It assumed area culture covered territori...

the purpose of this research was to analyze the impact of agronomic land use change to orchard in the west of urmia lake basin. the target population was about 12000 consisting of all the farmers in the west of urmia lake basin that changed their agronomic land use to orchard. using cochran’s formula and stratified random sampling method, 150 apple and grape growers were chosen. required data w...

Regional differences in clay mineralogy are found in British Lower Palaeozoic slate belts formed during Caledonian terrane amalgamation. Extensional basins in Wales, the northern Lake District and the Isle of Man are characterized by a greater diversity of species in clay mineral assemblages. Slates that evolved in these basins contain both the Kand Na-rich products of the 2:1 dioctahedral reac...
