Observations of changes in surface water over the western Siberia 3 lowland

چکیده
7 [1] We analyse the evolution of the fraction of water 8 surface (FWS), derived by SSM/I between 1988 and 2002 9 over the Western Siberia Lowland. This whole region 10 exhibits an increase in the amount of FWS that is in 11 agreement with the observed trends of the Ob river 12 discharge and precipitation. However, a similar increasing 13 trend is not found over the most important wetland area of 14 Sibirskie Uvaly Hills located in a region of sporadic 15 permafrost. These observations support the hypothesis that 16 climate warming in discontinuous permafrost environments 17 may lead to a reduction of small lakes and wetland areas. 18 Citation: Grippa, M., N. M.

Effects of Wind Erosion and Soil Salinization on Dust Storm Emission in Western Iran
Dust storms are known as hazardous problems in western part of Iran. Iraq is one of the main sources for dust storm arriving to the western part of Iran. The Radial Basis Function Network model (RBFN) has been used to assess wind erosion hazards in the source area of dust storms over several western Iranian cities. Normalized Difference Salinity Index (NDSI) was used to determine the changes in...
متن کاملReport of a Physical Oceanography Research Project over the Southern Continental Shelf of the Caspian Sea
Abstract The study presents monthly variations of seawater properties, monitoring water column stability and stratification over the southern shelf of the Caspian Sea which depends on collecting data. Field measurements were carried out during 13 cruises along the southern boundary of the sea. Spatial and temporal distributions of temperature, salinity and density were investigated. Monthl...
متن کاملComparison of surface salinity of Persian Gulf water using field data and FVCOM numerical model
This paper investigates and estimates the surface salinity changes of the Persian Gulf using the FVCOM numerical model. Sea level salinity (SSS) is one of the important parameters in oceanographic studies. The Persian Gulf is a semi-closed and shallow sea, which is high in the Persian Gulf due to its low rainfall, salinity and water density. One of the limitations of this region is the lack of ...
متن کاملInvestigating Aeolian Deposits in Gavkhouni playa located in central of Iran during Holocene Period
Introduction Identification of the climate changes is important for understanding the paleoenvironmental characteristics. Sedimentary evidence of the closed basins can be one of the most important methods for identifying the climatic periods and changes in the sedimentary environments. Gavkhouni Playa, as the lowland of the ZayandehRud River catchment area is located in an inter-mountainous...
متن کاملWestern lowland gorillas (Gorilla gorilla gorilla) change their activity patterns in response to frugivory.
The most important environmental factor explaining interspecies variation in ecology and sociality of the great apes is likely to be variation in resource availability. Relatively little is known about the activity patterns of western lowland gorillas (Gorilla gorilla gorilla), which inhabit a dramatically different environment from the well-studied mountain gorillas (G. beringei beringei). Thi...
