The ongoing changes affecting Lake Urmia (NW Iran) are revealed by the lake water level decrease (~7 m in last 20 yr) that was attributed to natural and anthropogenic causes but exact impact of these factors on state is still not identified. Indeed, lack detailed record environmental evolution past limits understanding actual future processes. Our project aims obtain a high-temporal resolution ...
In order to understand the pattern and trends of environmental evolution Lake Urmia (Iran), one largest terminal lakes in Western Asia before its level drop over past two decades, sediment cores (Golman 6, 8.0 m; Golman 7, 12.5 m) were collected from recently dried-out southwestern part lake. These represent a continuous sedimentary sequence, composite core, that was extensively studied for gra...
Recent improvements in earth observation technologies and Geographical Information System (GIS) based spatial analysis methods require us to examine the efficiency of different data-driven decision rules for soil salinity monitoring degradation mapping. The main objective this study was analyze environmental impacts Lake Urmia drought on risk plains surrounding hyper-saline lake. We monitored l...
Halophiles are in all three domains of life: Archaea, Bacteria and Eucarya. Halophilic microorganisms in addition to form major part of life biodiversity can have many biotechnological applications. The objective of this research is isolation and identification of halophilic bacteria from Urmia Lake in Iran and the study of its bacterial biodiversity. After sampling of brines from Urmia Lake fr...
