Salinity stress is a major factor inhibiting cereal yield throughout the world. Tolerance to salinity stress can be considered to contain three main components: Na(+) exclusion, tolerance to Na(+) in the tissues and osmotic tolerance. To date, most experimental work on salinity tolerance in cereals has focused on Na(+) exclusion due in part to its ease of measurement. It has become apparent, ho...

We study the signature of rainfall on S1cm, the sea surface salinity retrieved from the Soil Moisture and Ocean Salinity (SMOS) satellite mission first by comparing SMOS S1cm with ARGO sea surface salinity measured at about 5 m depth in the Intertropical Convergence Zone (ITCZ) and in the Southern Pacific Convergence Zone; second by investigating spatial variability of SMOS S1cm related to rain...

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...

As one of the most important physical parameters seawater, salinity is essential to study climatological change, trace seawater masses and model ocean dynamics. The traditional way conduct measurement in hydrographical observation use a standard conductivity-temperature-depth (CTD) probe where determination based on electrical conductivity. This article describes some developments recent years ...

considering the extent of salinity in soils of iran, abiotic stresses such as salinity are serious threat to agricultural production, yield and essential oil of medicinal plants. recognition of threshold for salt tolerance and determining the slope of yield loss in medicinal plants has an important role in the selection of suitable lands for their cultivation. the effect of salinity stress on s...

Porites coral-based sea surface temperature (SST) reconstructions are obtained from the measurement of skeleton Sr /Ca ratio. However, the influence of salinity in the incorporation of these trace elements in the Porites aragonitic skeleton is still poorly documented. Laboratory experiments indicate that in three different coral species (not including the widely used Porites genus), salinity do...

A passive/active L/S-band (PALS) microwave aircraft instrument to measure ocean salinity and soil moisture has been built and tested. Because the L-band brightness temperatures associated with salinity changes are expected to be small, it was necessary to build a very sensitive and stable system. This new instrument has dual-frequency, dual polarization radiometer and radar sensors. The antenna...

Retracing movements of euryhaline fishes using otolith chemistry analysis is a complex task, requiring detailed knowledge of the relationships between otolith and water chemistry for the target species and how these relationships change across dynamic environmental gradients in estuaries. In a controlled laboratory experiment, we quantified relationships between salinity and Sr:Ca and Ba:Ca rat...
