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...

Salinity causes oxidative stress in plants by enhancing production of reactive oxygen species, so that an efficient antioxidant system, of which ascorbic acid (AsA) is a key component, is an essential requirement of tolerance. However, antioxidant responses of plants to salinity vary considerably among species. Limonium stocksii is a sub-tropical halophyte found in the coastal marshes from Guja...

The thermodynamic balance of the Weddell Gyre is assessed from an inverse estimate of the circulation across the gyre’s rim. The gyre experiences a weak net buoyancy gain that arises from a leading-order cancelation between two opposing contributions, linked to two cells of water mass transformation and diapycnal overturning. The lower cell involves a cooling-driven densification of 8.4± 2.0 Sv...

Artificial reservoirs are created by dike construction in coastal areas to secure the agricultural water supply on the west coast of South Korea. These systems are found to retain brackish characteristics until total desalination is achieved. To evaluate the effects of salinity on the organic substances released from the sediment, a laboratory water-sediment column experiment was conducted to a...

Amid an increasing water scarcity in many parts of the world, virtual water trade as both a policy instrument and practical means to balance the local, national and global water budget has received much attention in recent years. Building upon the knowledge of virtual water accounting in the literature, this study assesses the efficiency of water use embodied in the international food trade fro...

Two major reverse osmosis seawater desalination plants are planned for construction in Spencer Gulf and Gulf St. Vincent, South Australia. A state-of-the-art and carefully calibrated hydrodynamic model (COHERENS) is employed to predict the fate of desalination brine in these sheltered inverse estuaries. In this study, we assume that the brine discharged has a salinity being twice that of ambien...

Abstract Seed germination is an important phase of plant development during which soil water availability is crucial. Salinity can affect seed germination in two ways: 1) Change of osmotic potential of available water, 2) toxicity effects. In this experiment, interactive effects of salinity and water deficit on germination criteria of two species of A, littoralis and A. logopoides were...

To trace offshore surface low-salinity water (LSW) in the northeastern Gulf of Mexico, a proxy was developed using the surface water beam attenuation coefficient (cp), and salinity matched with synchronous Seaviewing Wide Field-of-view Sensor (SeaWiFS) satellite data from three annual summer cruises (July 1998–August 2000) using a two-step empirical approach. First, a relationship between in-si...

in order to study the effect of irrigation water salinity on quality and quantity of sugar beet (beta vulgaris) at four growth stages, an experiment was conducted in rudasht salinity and drainage research center from 2004-2006. in this experiment, 11 different water salinity treatments and three sugar beet cultivars (ic, 7233 & 7233-p29*msc2) were considered using split plot design based on ran...

germination stage is an important stage of plant growth stage that often is affected by environmental stress including water and salinity stresses including drought and salinity. in order to study germination characteristics of scrophularia striatain water and salinity stress conditions at different temperatures an experiment was conducted. temperatures regimes included 5, 10, 15, 20, 25, 30 an...
