Chemical Ion Contributing to Seawater Salinity

Seawater Salinity and its effects on earth’s climate

Salinity is the saltiness or dissolved salt content of a body of water. The term salinity describes the level of different salts e.g. sodium chloride, magnesium and calcium sulphates etc dissolved in water.  Sea water has strong salinity due to its higher dissolved salts content. On an average, seawater has a salinity of about 3.5% (or 35 g/L). Sea water has almost all type…

The Shaky foundation of AADHAR

AADHAR project or the UIDAI scheme is a classic example of starting a factory first and then deciding what to produce from it. With no clear objective, the scheme was simply flagged off as a dream project with absolutely no clue as to what it will be used for. The AADHAR or the 12 digit…

Glaciers in India – Are Himalayan Glaciers really melting?

Himalayan glaciers alone supply an estimated 30-40% of the water to the Ganges which is particularly critical in the dry season prior to the Monsoon rains in India. Glaciers…
