the neogene intrusion masses in the noudeh-enghelab area located to the north of sabzevar ophiolite have cut the late cretaceous ophiolitic rocks, sedimentary- volcanic and eocene volcanic rocks and have been covered by pliocene and quaternary deposits. the margin is of lava with basalt, phyric andesite-basalt and andesite and the central parts (dome shaped) composed of phyric andesite-trachyan...

Current earth observation models do not take into account the influence of water salinity on the evaporation rate, even though the salinity influences the evaporation rate by affecting the density and latent heat of vaporization. In this paper, we adapt the SEBS (Surface Energy Balance System) model for large water bodies and add the effect of water salinity to the evaporation rate. Firstly, SE...

We estimated surface salinity flux and solar penetration from satellite data, and performed model simulations to examine the impact of including the satellite estimates on temperature, salinity, and dissolved oxygen distributions on the Louisiana continental shelf (LCS) near the annual hypoxic zone. Rainfall data from the Tropical Rainfall Measurement Mission (TRMM) were used for the salinity f...

the development of seminal and lateral root system plays a major role in plant access to water and nutrients under abiotic stress, especially salinity. in order to understand the relation between root growth responsesand shoot physiological indices oftwo bread wheat cultivars contrasting in salt tolerance (kavir and shiraz), a greenhouse experiment was conducted with two salinity levels (0 and ...

over the years, there has been an obvious pollution problem in lagos area, nigeria with high population of over eleven million and the near absence of waste management infrastructures. concentrations of some pollution parameters and trace elements (temperature, ph, salinity, so42-, no3-, po43-, f-, do, bod, cod and coliform, cr, co, ni, ag, cd and pb) were determined from water bodies of isolo ...

A change in the cycle of water from dry to wet regions of the globe would have far reaching impact on humanity. As air warms, its capacity to hold water increases at the Clausius-Clapeyron rate (CC, approximately 7% °C-1). Surface ocean salinity observations have suggested the water cycle has amplified at close to CC following recent global warming, a result that was found to be at odds with st...

Physico-chemical factors of river Pumba, Kerala has been analyzed to understand its relationship with the distribution of Giant river prawn, Macrobrachium rosenbergii in the water body. Water samples were taken from two sites on the basis of presence and absence of juveniles. Analysis of temperature, pH, turbidity, dissolved oxygen, dissolved carbon dioxide and salinity of the water samples rev...

Salinity stress is one of the most important problems of arid and semi-arid regions in the world. Based on Food and Agriculture Organization report, more than 40% of Iran’s under Irrigation lands, are against secondary salinity. The effects of salinity stress on some of vegetative traits and water relations on two rangeland plants species of leguminosae family was the main objective of this exp...

Background & Aim: The demand for freshwater resources has led scientists to use saline water and effluents. One of the cost-effective methods is the use of salinity-resistant plants to bioremediate saline effluents. Quinoa is a medicinal plant with high nutritional value that can control salinity stress in various ways. The present study was conducted with the aim of examining bioremediation of...

Phosphorus (P) is a key element in many biological processes of plants and animals. We aimed to investigate the effect of different salinity levels and Ca:Mg ratios of irrigation water arid lands on soil available P, soluble P, and P absorbed by the pistachio plant. For this purpose, a greenhouse experiment was conducted by sowing the seeds of pistachio in a factorial randomized block design wi...
