Mission India: Energy Security now and for the future

The signing of Paris agreement by India, concomitant with its submission for Intended Nationally Determined Contribution (INDC), has charted out the path that India plans to adopt for energy security. While India’s plan in the past has always looked good on the paper, how far India would be able to meet the target leaves a big question mark. In addition, India’s submission to INDC fails to address how India would meet its energy security in the transportation sector.

NASA Researchers Discover 7 Earth-Sized Exoplanets Nearby

With the discovery of seven Earth-sized planets orbiting a dwarf star, we are on the right track to find another habitable system! What makes this discovery by NASA’s Spitzer Space Telescope special is that this is the first time that a series of Earth-sized planets have been found around a single star, hence setting a new record for seemingly habitable planets around a single star outside our solar system. All seven planets may have water in the liquid state and be habitable in the future with...

Barren Island volcano in the Andaman basin is active

Barren Island volcano, located 140 km Northeast of Port Blair, is active and spewing smoke and lava again as reported by a team of scientists from CSIR-National Institute of Oceanography (CSIR-NIO), Goa. The scientific team led by Chief Scientist Dr Abhay V Mudholkar, on board CSIR-NIO’s research ship RV Sindhu Sankalp were busy collecting sea floor samples in the Andaman Basin near the Barren volcano when they witnessed the sudden spewing of ash on January 23,2017. The team immediately sprang...

Zealandia- The discovery of earth’s hidden continent

A group of scientist in Australia who have been working and gathering data for the past twenty years claim that New Zealand sits atop a previously unknown continent which is 94% underwater. Eight GNS Science geologists headed by Nick Mortimer along with colleagues from Victoria University, the Geological Survey of New Caledonia, and the University of Sydney summarize the evidence that 4.9 million square kilometers of the South West Pacific Ocean is underlain by a submerged continent. The lead...

Breaking Records – The ISRO Way

With the successful launch of 104 satellites from a single rocket on February 15, 2017 at  9:28 AM IST, ISRO has managed to once again prove to the world that no matter what goals are set for it, ISRO manages to blow them all to smithereens. By effectively managing the launch of 104 satellites in one go, and by one rocket, ISRO has beaten every other space agencies record by a large margin. For comparison, now the second place for most satellites in one go goes to the Russian Space Agency. The Russian...

Kashmir Valley Snow- A blessing for all

Snowfall recorded in Kashmir Valley in the last few days has broken previously held records at some of the stations. The snowfall has been described as ‘above normal’ rainfall by Sonam Lotus, Director MeT Department, Srinagar. In a conversation with GnY, he said, “Snowfall at some of the stations have broken records as old as 30 years. But not all stations have broken records. There is no doubt that we have seen very good snowfall this year and though it has caused inconvenience to many,...


Seabed Mining

The limited opportunities to mine for minerals on land is making the world consider deep seabed mining as an alternative. But this can pose major destruction to marine biodiversity, given our limited knowledge of the effects of disturbing the high seas, especially in oxygen-minimum zones.


An Ocean at Risk

Climate change and anthropogenic factors, are causing many marine species to die out, resulting in a devastating impact on coastal populace. Replenishing mangrove ecosystems can provide a viable solution to tackle this problem.

Analyzing past monsoons with foraminifera

Stable oxygen isotopic composition (δ18O) of foraminifera from the sediments of the Northern Indian Ocean has been used to decipher past changes in the intensity of the South Asian Monsoon. The interpretation of planktonic foraminifera δ18O is mostly based on a combination of sea surface temperature, monsoon runoff and the global ice-volume effect. During summer, the eastward flowing summer monsoon current carries the high salinity water from the Arabian Sea to the Bay of Bengal, whereas the Bay of Bengal...


Coral Reefs in India: Status Report

The study of coral reefs have had a late beginning.  Earlier studies had accounted for only 218 species. Successive surveys made between 2008 and 2013 have reported the occurrence of 519 hard corals in India. Among the four major reefs in India, Andaman and Nicobar Islands are rich in coral as compared to the relatively poorer Gulf of Kachchh.  The isles of Lakshadweep, similarly,  have more species than the Gulf of Mannar.  Among the deepwater (ahermatypic) corals, 227 species have been reported...
