we quantified the distribution, abundance and assemblage structure of macrofauna at 22 stations in gorgan bay, seasonally in 2012-2013. also, depth, temperature, salinity, do, tom and sediment particle size were measured in each station. the highest concentration of tom was measured near the western littoral zone (10.22) while the mouth part and north-eastern area was characterized by the lowes...

introduction temporal and spatial change of meteorological and environmental variables is very important. these changes can be predicted by numerical prediction models over time and in different locations and can be provided as spatial zoning maps with interpolation methods such as geostatistics (16, 6). but these maps are comparable to each other as visual, qualitative and univariate for a lim...

in this paper the minimum temperatures of 54 weather stations collected for a 31-year period were analyzed for zoning the frost regions in iran. the results of this study show that the average of the number of frost days per year was 62, and the average temperature was 3 degrees of centigrade below zero. dey the tenth month in the iranian calendar, december 22-january 20 with an average of 28, ...

The morphological states of Guyana’s coastal system, at various spatial and temporal scales, are found to be influenced by the formation and migration of mudbanks. Stationary and propagating mudbanks along the coast are investigated with the use of multiple data sources, including aerial photographs, satellite imagery, GPS measurements, and a time series of coastal profile data (1941-1987...

      Aridity as a spatial concept and drought as a temporal concept have always been studied in different aspects as two distinct categories. However, both concepts indicate anomalies from normal condition. Several indices have been introduced to examine each of these concepts using one or more hydrological cycle’s components. Meanwhile, soil moisture and changes in its spatial and temporal va...
