Using over 1.6 million profiles of salinity, potential temperature, and neutral density from historical archives and the international Argo Program, this study develops the three-dimensional field of multidecadal linear change for ocean-state properties. The period of analysis extends from 1950 to 2008, taking care to minimize the aliasing associated with the seasonal and major global El Niño–Southern Oscillation modes. Large, robust, and spatially coherent multidecadal linear trends in salinity to 2000-dbar depth are found.

Recession of the Himalayan glaciers is a major concern today with IPCC

Radiogenic isotopes (3H and 14C) and stable isotope (18O) together with TDS, EC and salinity of water were used to discriminate qualitative and quantitative groundwater age, probable recharge time, flow respectively in groundwater of Challaghatta valley, Bangalore.

There's no shortage of water on the blue planet

Water characteristics of Kandla creek, monitored seasonally from 2002 to 2006 at four locations (mouth, cargo jetty, oil jetty and junction), indicated significant increases in nutrients, petroleum hydrocarbons (PHc) and phenols from anthropogenic additions, while increases in turbidity, total suspended solids (TSS) and salinity from natural effects.

India has a long coastal line of over 7500 km supporting vast habitats such as lagoons, backwaters, estuaries, coral reefs and mangrove swamps. Among them, the mangrove ecosystem commands the highest importance because of its biological productivity and specialized diversity. After coral reefs, mangrove forests have the highest productivity among the coastal wetlands.

Rajahmundry, March 22: Coastal villages in West Godavari are being plagued by high saline content in their drinking water due to seepage of sea water into the ground water. Sources say that the main reason behind this is excessive quarrying of sand on the Godavari river bed.

Ratan Mondol, 86, is one of the first environmental refugees from the Sunderbans. Old and bent, Mondal recalls how the rising sea destroyed his life.

The above ground biomass (AGB) and carbon stock of Excoecaria agallocha were estimated in western and central Indian Sundarbans for five successive years (2005-2010). The two sectors are drastically different with respect to salinity on account of massive siltation that prevents the flow of fresh water of the River Ganga to the central sector of Indian Sundarbans.

Hambantota District is a major paddy (rice) producing area in the southern coastal region of Sri Lanka. Communities here have been experiencing salt water intrusion into their rice fields, leading to reduced yields. This has been caused largely by seawater contamination of irrigation systems.
